Degenerative Joint Disease (DJD)/Osteoarthrosis(OA), which is also known as osteoarthrosis, is a progressive disorder of the joints caused by gradual loss of cartilage and resulting in the development of bony spurs and cysts at the margins of the joints. The name osteoarthritis comes from three Greek words meaning bone, joint, and inflammation.
Osteoarthritis is a multifactorial process in which mechanical factors have a central role and is characterized by changes in the structure and function of the whole joint. [Rx] There is no cure, and current therapeutic strategies are primarily aimed at reducing pain and improving joint function. We searched Medline for relevant articles (1966 to January 2006) and the Cochrane library (to first quarter of 2006) and consulted experts in rheumatology to produce a narrative review with an update on management for primary care doctors. We concentrated on osteoarthritis of the knee as this is associated with the greatest public health burden.
Osteoarthritis (OA) a common disease of an aged population and one of the leading causes of disability. The incidence of knee OA is rising by increasing average age of the general population. Age, weight, trauma to joint due to repetitive movements, in particular, squatting and kneeling are common risk factors of knee OA. Several factors including cytokines, leptin, and mechanical forces are pathogenic factors of knee OA. In patients with knee pain attribution of pain to knee OA should be considered with caution. Since a proportion of knee OA is asymptomatic and in a number of patients identification of knee OA is not possible due to the low sensitivity of radiographic examination. In this review data presented in regard to prevalence, pathogenesis, risk factors.
Epidemiology /Etiology of Osteoarthritis of knee
Knee osteoarthritis is classified as either primary or secondary, depending on its cause. Primary knee osteoarthritis is the result of articular cartilage degeneration without any known reason. This is typically thought of as degeneration due to age as well as wear and tear. Secondary knee osteoarthritis is the result of articular cartilage degeneration due to a known reason.
Osteoarthritis is the most prevalent form of arthritis and occurs especially in the knee joint. It affects nearly 6% of all adults, but more women are affected than men.“According to a number of published reports, anywhere from 6% to over 13% of men, but between 7% and 19% of women, over 45 years of age are affected, resulting in a 45% less risk of incidence in men (Coleman, et al).
Possible Causes of Secondary Knee OA
Congenital or malformation of the limb
Sickle cell disease
Causes of Osteoarthritis (OA) of Knee
Articular cartilage increased the water content
- Alterations in proteoglycans eventual decrease in the number of proteoglycans
- Collagen abnormalities organization and orientation are lost
- Binding of proteoglycans to hyaluronic acid
Synovium and capsule
An early phase of OA
- Mild inflammatory changes in the synovium
The middle phase of OA
- Moderate inflammatory changes of the synovium
- Synovium becomes hypervascular
Late phases of OA
- The synovium becomes increasingly thick and vascular
- Subchondral bone attempts to remodel forming lytic lesion with sclerotic edges (different than bone cysts in RA) bone cysts form in late stages
- Proteolytic enzymes matrix metalloproteases (MMPs)
Responsible for cartilage matrix digestion
- Aggrecanase-1 (ADAM-TS-4)
Tissue inhibitors of MMPS (TIMPs)
- Control MMP activity preventing excessive degradation
- The imbalance between MMPs and TIMPs has been demonstrated in OA tissues
Secreted by synoviocytes and increase MMP synthesis, examples
Genes potentially linked to OA
- vitamin D receptor
- estrogen receptor 1
- inflammatory cytokines
- leads to the catabolic effect
- BMP-2, BMP-5
Age is not the only factor that plays a role in the evolution of OA. Other risk factors are
- Joint hypermobility or instability
- Sports stress with high impact loading
- Repetitive knee bending or heavy weight lifting
- Specific occupations
- Peripheral neuropathy
- Injury to the joint
- History of immobilization
- Family history
Occupation – prolonged standing and repetitive knee bending
Muscle weakness or imbalance
Health – metabolic syndrome
Gender – females more common than males
How does a normal knee work?
- Your knee joint is where your thigh bone (femur) and your shin bone (tibia) meet. It allows the bones to move freely but within limits.
- Your knee is the largest joint in the body and also one of the most complicated. It needs to be strong enough to take our weight and must lock into position so we can stand upright. But it also has to act as a hinge so we can walk, and it must withstand extreme stresses, twists, and turns, such as when we run or play sports.
When your knee has osteoarthritis its surfaces become damaged and it doesn’t move as well as it should do. The following happens:
- The cartilage becomes rough and thin – this can happen over the main surface of your knee joint and in the cartilage underneath your kneecap.
- The bone underneath the cartilage reacts by growing thicker and becoming broader.
- All the tissues in your joint become more active than normal as if your body is trying to repair the damage.
- The bone at the edge of your joint grows outwards, forming bony spurs called osteophytes.
- The synovium may swell and produce extra fluid, causing the joint to swell – this is called an effusion or sometimes water on the knee.
- The capsule and ligaments slowly thicken and contract.
These changes in and around your joint are partly the result of the inflammatory process and partly an attempt by your body to repair the damage. In many cases, your body’s repairs are quite successful and the changes inside your joint won’t cause much pain or, if there is the pain, it’ll be mild and may come and go.
However, in other cases, the repair doesn’t work as well and your knee is damaged. This leads to instability and more weight being put onto other parts of the joint. This can cause symptoms to become gradually worse and more persistent over time.
Risk Factors can be Classified into Primary & secondary
- A number of studies have shown that there is a greater prevalence of the disease among siblings and especially identical twins, indicating a hereditary basis. Although a single factor is not generally sufficient to cause the disease, about half of the variation in susceptibility has been assigned to genetic factors
- As early human ancestors evolved into bipeds, changes occurred in the pelvis, hip joint, and spine which increased the risk of osteoarthritis. Additionally, genetic variations that increase the risk were likely not selected against because usually problems only occur after reproductive success.
- The development of osteoarthritis is correlated with a history of previous joint injury and with obesity, especially with respect to knees. Since the correlation with obesity has been observed not only for knees but also for non-weight bearing joints and the loss of body fat is more closely related to symptom relief than the loss of body weight, it has been suggested that there may be a metabolic link to body fat as opposed to just mechanical loading.
- Changes in sex hormone levels may play a role in the development of osteoarthritis as it is more prevalent among post-menopausal women than among men of the same age. A study of mice found natural female hormones to be protective while injections of the male hormone dihydrotestosterone reduced protection.
This type of osteoarthritis is caused by other factors but the resulting pathology is the same as for primary osteoarthritis:
- Older age – The risk of osteoarthritis increases with age.
- Sex – Women are more likely to develop osteoarthritis, though it isn’t clear why.
- Obesity – Carrying extra body weight contributes to osteoarthritis in several ways, and the more you weigh, the greater your risk. Increased weight puts added stress on weight-bearing joints, such as your hips and knees. In addition, fat tissue produces proteins that may cause harmful inflammation in and around your joints.
- Joint injuries – Injuries, such as those that occur when playing sports or from an accident, may increase the risk of osteoarthritis. Even injuries that occurred many years ago and seemingly healed can increase your risk of osteoarthritis.
- Certain occupations – If your job includes tasks that place repetitive stress on a particular joint, that joint may eventually develop osteoarthritis.
- Genetics – Some people inherit a tendency to develop osteoarthritis.
- Bone deformities – Some people are born with malformed joints or defective cartilage, which can increase the risk of osteoarthritis.
- Inflammatory diseases – (such as Perthes’ disease), (Lyme disease), and all chronic forms of arthritis (e.g., costochondritis, gout, and rheumatoid arthritis). In gout, uric acid crystals cause the cartilage to degenerate at a faster pace.
- Diabetes doubles – the risk of having a joint replacement due to osteoarthritis and people with diabetes have joint replacements at a younger age than those without diabetes.
- Congenital disorders of joints
- Ehlers-Danlos Syndrome
- Hemochromatosis and Wilson’s disease
- Injury to joints or ligaments (such as the ACL), as a result of an accident or orthopedic operations.
- Ligamentous deterioration or instability may be a factor.
- Marfan syndrome
- Joint infection
The symptom of Osteoarthritis (OA) of Knee
- Pain (particularly when you’re moving your knee or at the end of the day – this usually gets better when you rest)
- Stiffness (especially after rest – this usually eases after a minute or so as you get moving)
- Crepitus, a creaking, crunching, grinding sensation when you move the joint
- Hard swellings (caused by osteophytes)
- Soft swellings (caused by extra fluid in the joint).
- Loss of flexibility – You may not be able to move your joint through its full range of motion.
- Grating sensation – You may hear or feel a grating sensation when you use the joint.
- Bone spurs – These extra bits of bone, which feel like hard lumps, may form around the affected joint.
Other symptoms can include
- your knee giving way because your muscles have become weak or the joint structure is less stable
- your knee not moving as freely or as far as normal
- your knees becoming bent and bowed
- the muscles around your joint looking thin or wasted.
It’s unusual, but some people have pain in their knee that wakes them up at night. This generally only happens with severe osteoarthritis.
- You’ll probably find that your pain will vary and that you have good days and bad days, sometimes depending on how active you’ve been but sometimes for no clear reason.
- Some people find that changes in the weather (especially damp weather and low pressure) make their pain and stiffness worse. This may be because nerve fibers in the capsule of their knee are sensitive to changes in atmospheric pressure.
Diagnosis of Osteoarthritis (OA) of Knee
During the physical examination, your doctor will look for:
- Joint swelling, warmth, or redness
- Tenderness about the knee
- The range of passive (assisted) and active (self-directed) motion
- Instability of the joint
- Crepitus (a grating sensation inside the joint) with movement
- Pain when weight is placed on the knee
- Problems with your gait (the way you walk)
- Any signs of injury to the muscles, tendons, and ligaments surrounding the knee
- Involvement of other joints (an indication of rheumatoid arthritis
For the grading of osteoarthritis in the knee, the most reliable systems are the International Knee Documentation Committee (IKDC) system and the Ahlbäck system, which have been found to be superior to for example systems by Kellgren-Lawrence, Fairbank, Brandt, and Jäger-Wirth. These findings refer to posteroanterior weight-bearing projection radiographs made with the knee in 45° of flexion.
|I||Joint space narrowing, with or without subchondral sclerosis. Joint space narrowing is defined by this system as a joint space less than 3 mm, or less than half of the space in the other compartment, or less than half of the space of the homologous compartment of the other knee.|
|II||Obliteration of the joint space|
|III||Bone defect/loss <5 mm|
|IV||Bone defect/loss between 5 and 10 mm|
|V||Bone defect/loss >10 mm, often with subluxation and arthritis of the other compartment|
For the patellofemoral joint, a classification by Merchant 1974 uses a 45° “skyline” view of the patella
|1 (mild)||Patellofemoral joint space > 3mm|
|2 (moderate||Joint space < 3 mm but no bony contact|
|3 (severe)||Bony surfaces in contact over less than one-quarter of the joint surface|
|4 (very severe)||Bony contact throughout the entire joint surface|
Goldberg RJ recommends the following as a common approach to the examination of all joints
Make sure the area is well exposed—no clothing covering either side. Patient gowns come in handy
Carefully inspect the joint or joints in question – Are there signs of inflammation or injury (swelling, redness, warmth)? Deformity? Because many joints are symmetrical, compare it with the opposite side
Understand normal functional anatomy – What does this joint normally do?
Observe the joint – while the patient attempts to perform the normal activity. What can’t the patient do? What specifically limits him/her? Was there a discrete event (eg, trauma) that caused this? If so, what was the mechanism of injury?
Palpate the joint in question – Is there warmth? Point tenderness? If so, over what anatomic structures?
Assess the range of motion – both active (patient moves it) and passive (you move it). If the active range of motion is limited, determine causes of pain
Perform strength and neurovascular assessments
Perform specific provocative maneuvers related to pathology occurring in that joint (Goldberg[Rx])presents some for each joint)
In the setting of acute injury and pain, it is often very difficult to assess a joint because the patient “protects” the affected area, limiting movement and thus your examination. It helps to examine the unaffected side first. This will help to set the patient at ease and will help the physician to gain a sense of the patient’s normal range of motion.
Laboratory tests and x-rays are often used in addition to these criteria.
- Osteoarthritis of the hand can often be diagnosed on the basis of these criteria alone, and laboratory tests and x-rays may be unnecessary. But in some cases it needed.
- A normal erythrocyte sedimentation rate (ESR)
- The presence of bony outgrowths (osteophytes) on x-rays
- The presence of joint space narrowing on x-rays, indicating a loss of cartilage
The number of characteristics associated with knee pain varies depending on whether a diagnosis is being made using clinical criteria only, using clinical and radiographic criteria, or using clinical and laboratory criteria, as follows
Crepitus on active joint motion
Morning stiffness less than 30 minutes’ duration
AQge older than 50 years
Bony enlargement of the knee on examination
Bony tenderness of the knee on examination
No palpable warmth.
Crepitus on active motion
Morning stiffness less than 30 minutes’ duration
Age older than 50 years.
Crepitus on active joint motion
Morning stiffness less than 30 minutes’ duration
Age older than 50 years
Bony tenderness to palpation
No palpable warmth
Erythrocyte sedimentation rate below 40 mm/h
A rheumatoid factor less than 1:40
Synovial fluid is consistent with OA (white blood cell count < 2000/μL).
Laboratory tests may be recommended to help diagnose OA by ruling out conditions with similar symptoms.
- X-rays are often helpful for tracking the status of OA over time, but x-rays may appear normal during the early stages.
- Other types of imaging tests, such as ultrasound and magnetic resonance imaging (MRI), may be used to detect damage to cartilage, ligaments, and tendons, which cannot be known by the following an investigation
- Muscle atrophy
- Normal quadriceps circumference >10 cm (VMO), 15 cm (quadriceps)
- Stride length
- Muscle weakness
Standing limb alignment
- Neutral, varus, valgus
- Joint line tenderness
Tenderness over soft tissue structures
- Pes anserine bursae
- Patellar tendon
- Iliotibial band
Point of maximal tenderness
- Patella balloting
Active and passive
Flexion/extension normal range
- 10° extension (recurvatum) to 130° flexion
Rotation varies with flexion
- In full extension, there is ma inimal rotation
- At 90° flexion, 45° ER and 30° IR
- In full extension, essentially 0°
- At 30° flexion, a few degrees of passive motion possible
- Medial thigh – obturator
- Anterior thigh – femoral
- Posterolateral calf – sciatic
- Dorsal foot – peroneal
- Plantar foot – tibial
- Thigh adduction – obturator
- Knee extension – femoral
- Knee flexion – sciatic
- Toe extension – peroneal
- Toe flexion – tibial
- Dorsalis pedis
- Posterior tibial
- ABI < 0.9 is abnormal
- Large hemarthrosis
- Quadriceps avoidance gait (does not actively extend knee)
- Extension to flexion: reduces at 20-30° of flexion
- The patient must be completely relaxed (easier to elicit under anesthesia)
- Mimics the actual giving way event
- Useful to quantify anterior laxity
- Measured with knee in slight flexion and 10-30° externally rotation
Posterior sag sign – The patient lies supine with hips and knees flexed to 90°, examiner supports ankles and observes for a posterior shift of the tibia as compared to the uninvolved knee
Posterior drawer (at 90° flexion) – With the knee at 90° of flexion, a posteriorly directed force is applied to the proximal tibia and posterior tibial translation is quantified & the medial tibial plateau of a normal knee at rest is ~1 cm anterior to the medial femoral condyle
Most accurate maneuver for diagnosing PCL injury Quadriceps active test– attempt to extend a knee flexed at 90° to elicit quadriceps contraction positive if the anterior reduction of the tibia occurs relative to the femur
Valgus instability = medial opening
- 30° only – isolated MCL
- 0° and 30° – combined MCL and ACL and/or PCL
- Grade I: 0-5 mm opening
- Grade II: 6-10 mm opening
- Grade III: 11-15 mm opening
Anterior Drawer with tibia in external rotation
- grade III MCL tears often associated with ACL and posteriomedial corner tears
- pthe ostive test will indicate associated ligamentous injury
Varus instability = lateral opening
- 30° only – isolated LCL
- 0° and 30° – combined LCL and ACL and/or PCL
- Varus opening and increased external tibial rotatory instability at 30° – combined LCL and posterolateral corner
Varus thrust or hyperextension thrust
Varus stress test
- Varus laxity at 0° indicates both LCL & cruciate (ACL or PCL) injury
- Varus laxity at 30° indicates LCL injury.
- > 10° ER asymmetry at 30° only consistent with isolated PLC injury
- > 10° ER asymmetry at 30° & 90° consistent with PLC and PCL injury
Reversed pivot shift test
- With the knee positioned at 90°, ER and valgus forces are applied to tibia as the knee is extended, the tibia reduces with a palpable clunk tibia reduces from a posterior subluxed position at ~20° of flexion to a reduced position in full extension (reduction force from IT band transitioning from a flexor to an extensor of the knee)
External rotation recurvatum test
- positive when the leg falls into ER and recurvatum when the lower extremity is suspended by the toes in a supine patient
- Peroneal nerve assessment injury present with altered sensation to foot dorsum and weak ankle dorsiflexion
- Joint line tenderness
- Flex the knee and place a hand on the medial side of knee externally rotate the leg and bring the knee into extension
- A palpable pop or click is a positive test and can correlate with a medial meniscus tear
- The absence of swelling supports ligamentous laxity and habitual dislocation mechanism
- Medial-sided tenderness (over MPFL)
- Increase in passive patellar translation
- Measured in quadrants of translation (midline of the patella is considered “0”) and should be compared to the contralateral side
- Normal motion is <2 quadrants of patellar translation
- Lateral translation of medial border of patella to the lateral edge of the trochlear groove is considered “2” quadrants and is an abnormal amount of translation
- Patellar apprehension
- Increased Q angle
- Excessive lateral translation in extension which “pops” into the groove as the patella engages the trochlea early inflection
- Associated with patella alta

History and Physical
- Patients typically present to their healthcare provider with the chief complaint of knee pain. It is essential to obtain a detailed history of their symptoms. Pay careful attention to history as knee pain can be referred from the lumbar spine or the hip joint. It is equally important to obtain a detailed medical and surgical history to identify any risk factors associated with secondary knee OA.
The history of the present illness should include the following
Onset of symptoms
The specific location of pain
Duration of pain and symptoms
Characteristics of the pain
Alleviating and aggravating factors
Any radiation of pain
The specific timing of symptoms
Severity of symptoms
The patient’s functional activity
Clinical Symptoms of Knee OA
Typically of gradual onset
Worse with prolonged activity
Worse with repetitive bending or stairs
Worse with inactivity
Worsening over time
Better with rest
Better with ice or anti-inflammatory medication
Decreased ambulatory capacity
Physical examination of the knee should begin with a visual inspection. With the patient standing, look for periarticular erythema and swelling, quadriceps muscle atrophy, and varus or valgus deformities. Observe gait for signs of pain or abnormal motion of the knee joint that can be indicative of ligamentous instability. Inspect the surrounding skin for the presence and location of any scars from previous surgical procedures, overlying evidence of trauma, or any soft tissue lesions.
Range of motion (ROM) testing is a very important aspect of the knee exam. Active and passive ROM with regard to flexion and extension should be assessed and documented.
Palpation along the bony and soft tissue structures is an essential part of any knee exam. The palpatory exam can be broken down into the medial, midline, and lateral structures of the knee.
Areas of focus for the medial aspect of the knee
Vastus medialis obliquus
Superomedial pole patella
A medial facet of the patella
Origin of the medial collateral ligament (MCL)
Midsubstance of the MCL
Broad insertion of the MCL
Medial joint line
Pes anserine tendons and bursa
Areas of focus for the midline of the knee
Superior pole patella
Areas of focus for the lateral aspect of the knee
Lateral facet patella
Lateral collateral ligament (LCL)
Lateral joint line
A thorough neurovascular exam should be performed and documented. It is important to assess the strength of the quadriceps and hamstring muscles as these often times will become atrophied in the presence of knee pain. A sensory exam of the femoral, peroneal, and tibial nerve should be assessed as there may be concomitant neurogenic symptoms associated. Palpation of a popliteal, dorsal pedis, and the posterior tibial pulse is important as any abnormalities may raise the concern for vascular problems. Other knee tests may be performed, depending on clinical suspicion based on history.
Special knee tests
Patella apprehension – patellar instability
J-sign – patellar maltracking
Patella compression/grind – chondromalacia or patellofemoral arthritis
Medial McMurray – a medial meniscus tear
Lateral McMurray – lateral meniscus tear
Thessaly test – a meniscus tear
Lachman – anterior cruciate ligament (ACL) injury
Anterior drawer – ACL injury
Pivot shift – ACL injury
Posterior drawer – posterior cruciate ligament (PCL) injury
Posterior sag – PCL injury
Quadriceps active test – PCL injury
Valgus stress test – MCL injury
Varus stress test – LCL injury
Any potential cause of local or diffuse knee pain should be considered in the differential diagnosis of knee osteoarthritis.

Treatment of Osteoarthritis (OA) of Knee
Treatment for knee osteoarthritis can be broken down into non-surgical and surgical management. Initial treatment begins with non-surgical modalities and moves to surgical treatment once the non-surgical methods are no longer effective. A wide range of non-surgical modalities is available for the treatment of knee osteoarthritis. These interventions do not alter the underlying disease process, but they may substantially diminish pain and disability.
The non-pharmacological approach includes
- Education –Encourage patients to participate in self-management programs (such as those conducted by the Arthritis Foundation in the United States and Arthritis Care in the United Kingdom), and provide resources for social support and instruction on coping skills.
- Weight loss – Encourage overweight patients with osteoarthritis of the hip and knee to lose weight through a combination of diet and exercise.[Rx]
- Exercise – increases aerobic capacity, muscle strength, and endurance and also facilitates weight loss. All people capable of exercise should be encouraged to take part in a low impact aerobic exercise program (walking, cycling, or swimming or other aquatic exercise). Exercises to strengthen the quadriceps lead to reductions in pain and improvements in function.
- Physical therapy – consists of several strategies to facilitate the resolution of symptoms and improve functional deficits, including a range of motion exercise, muscle strengthening, muscle stretching, and soft tissue mobilization.
- Knee braces and orthotics – For those with the instability of the knee and varus misalignment, valgus bracing and orthotics shift the load away from the medial compartment and, in doing so, may provide relief of pain and improvement in function.[Rx] Though some research has shown that heel wedges can reduce medial compartment loads, there is no evidence that used alone, they improve knee symptoms.[Rx] Appropriate supportive footwear should be worn by people who have osteoarthritis of the knee and hip.
- Shoe inserts – Consider trying splints, braces, shoe inserts or other medical devices that can help reduce your pain. These devices can immobilize or support your joint to help you keep pressure off it.
The first-line treatment for all patients with symptomatic knee osteoarthritis includes patient education and physical therapy. A combination of supervised exercises and a home exercise program have been shown to have the best results. These benefits are lost after 6 months if the exercises are stopped. The American Academy of Orthopedic Surgeons (AAOS) recommends this treatment.
Treatment of Osteoarthritis (OA) of Knee
The goal of treatment is to decrease pain and increase mobility.
- Analgesics – Paracetamol (up to 4 g/day) is the oral analgesic of choice for mild to moderate pain in osteoarthritis. NSAIDs should be added or substituted in patients who respond inadequately and are sometimes the first choice because of greater efficacy and patients’ preference.[rx] There are, however, certain disadvantages of routinely using NSAIDs—for example, all NSAIDs (non-selective and COX 2 selective) are associated with potential toxicity, particularly in elderly people. COX 2 selective inhibitors have also been associated with an increased risk for cardiovascular disease. Rofecoxib, a COX 2 selective inhibitor, was recently withdrawn because of such concerns. In people with an increased gastrointestinal risk, nonselective NSAIDs plus a gastroprotective agent or a selective COX 2 inhibitor should be used. Opioid analgesics are useful alternatives in patients in whom NSAIDs are contraindicated, ineffective, or poorly tolerated. Topical formulations of NSAIDs and capsaicin may be helpful.
- Antidepressants – A Drugs that block pain messages from your brain and boost the effects of endorphins (your body’s natural painkillers).
- Nonsteroidal anti-inflammatory drugs (NSAIDs) Common pain remedies such as aspirin, acetaminophen, ibuprofen, and naproxen can offer short-term relief. All are available in low doses without a prescription. Other medications, including muscle relaxants and anti-seizure medications, treat aspects such as muscle spasms and damaged nerves.
- Corticosteroid injections – Your doctor will inject a steroid such as prednisone into your thumb joints. Steroids make the inflammation go down. However, because of side effects, they are used sparingly
- Anesthetics – Used with precision, an injection of a “nerve block” can stop the pain for a time.
- Muscle Relaxants – These medications provide relief from spinal muscle spasms.
- Neuropathic Agents – Drugs(pregabalin & gabapentin) that address neuropathic—or nerve-related—pain. This includes burning, numbness, and tingling.
- Opioids – Also known as narcotics, these medications are intense pain relievers that should only be used under a doctor’s careful supervision.
- Topical Medications: These prescription-strength creams, gels, ointments, patches, and sprays help relieve pain and inflammation through the skin.
- Calcium & vitamin D3 – to improve bones health and healing fracture.
- Glucosamine & diacerein– can be used to tightening the loose tension and regenerate cartilage or inhabit the further degeneration of cartilage.
- Muscle relaxants – such as cyclobenzaprine might be prescribed to relieve the discomfort associated with muscle spasms. However, these medicines might cause confusion in older people. Depending on the level of pain, prescription pain medicines might be used in the initial period of treatment.
- Over-the-counter – non-narcotic pain relievers and anti-inflammatory medications are usually the first choices of therapy for arthritis of the knee. Acetaminophen is a simple, over-the-counter pain reliever that can be effective in reducing arthritis pain that is following
- Glucosamine compounds – in particular, have attracted a great deal of attention, mostly in the lay press. Possibly as a function of this publicity, osteoarthritis is the leading medical condition for which people use alternative therapies. Glucosamine and chondroitin seem to have the same benefit as a placebo,[Rx]and there is controversy over whether they also have structure modifying benefits.
- COX-2 inhibitors
- Glucosamine and chondroitin sulfate
- Corticosteroid injections
- Hyaluronic acid (HA)
Viscosupplementation with hyaluronic acid (HA) – Injection into the knee with HA (similar to the main component in cartilage) has been reported to provide temporary pain relief for up to three months. Evidence to date on the use of HA has been contradictory, and recommendations regarding its use remain inconclusive[,Rx ]Currently, the American Academy of Orthopaedic Surgeons does not recommend using hyaluronic acid for patients with symptomatic end-stage osteoarthritis (OA) of the knee.
There are no existing data that any of the HA injections – will cause regression of osteophytes, subchondral bone remodeling, or regeneration of cartilage and meniscus in patients with substantial, irreversible bone and cartilage damage. Further investigations are required to determine whether high-molecular-weight and cross-linked preparations of HA have superior efficacy compared with other HA preparations or other currently available treatments.
In addition, studies involving long-term outcomes of efficacy – safety, and economic cost-benefit analyses are needed.Rx Because of the paucity of data supporting the effectiveness of HA injections to justify their cost, careful patient selection and decreasing the use of HA among patients with end-stage knee OA may represent a substantial cost reduction without negatively affecting the quality of health care.Rx
Intra-articular corticosteroids – Intra-articular injections of corticosteroids have long been used to try to relieve symptoms from knee OA, but studies addressing their efficacy have been contradictory. The American Academy of Orthopaedic Surgeons guidelines for nonoperative treatment options for patients with OA of the knee does not recommend for or against the use of intra-articular corticosteroids into the knee.Rx Furthermore, a recent Cochrane systematic review concluded that clinically important benefits of one to six weeks remain unclear because of the overall quality of the studies, the heterogeneity between trials, and the presence of small-study effects.Rx
- Intra-articular hyaluronan – Though the meta-analyses reviewing the efficacy of intra-articular hyaluronan are not in complete agreement, mainly because of variation in study methods, most suggest that the effect size is relatively small and the placebo response is significant.Rx
- Cortisone shots – Injections of corticosteroid medications may relieve pain in your joint. During this procedure, your doctor numbs the area around your joint, then places a needle into space within your joint and injects the medication. The number of cortisone shots you can receive each year is limited because the medication can worsen joint damage over time.
- Lubrication injections – Injections of hyaluronic acid derivatives (Hyalgan, Synvisc) may offer pain relief by providing some cushioning in your knee. These agents are similar to a component normally found in your joint fluid.
- Realigning bones – During a surgical procedure called an osteotomy, the surgeon cuts across the bone either above or below the knee to realign the leg. Osteotomy can reduce knee pain by shifting your body weight away from the worn-out part of your knee.
Cell-based therapies – Cell-based therapies for knee OA are in development stages. A recent systematic review suggested that intra-articular cellular injections for OA and focal cartilage defects in the human knee had positive results and seemed safe. However, improvement in patient symptoms was modest and a placebo effect could not be disregarded. The overall quality of the literature was poor; therefore, accurate assessment and optimization of these therapies will require further research. Rx Most of the studies analyzed reported on the use of autologous cellular therapies. Bone marrow-derived cells were the source chosen more often, followed by adipose-derived cells and blood stem cells.
Platelet-rich plasma – Multiple studies and systematic reviews have reported on the use of intra-articular PRP for the treatment of knee OA.Rx Initial observations support an inference that PRP appears to be safe. Although some transient pain or swelling has been reported after its use, these symptoms typically resolve within two to three days, and no long-term side effects have been reported.
Use of PRP – especially a lower leukocyte concentration known as leukocyte-poor PRP, showed improved results compared with HA and placebo, showing beneficial effects of amelioration in pain and improvement in function about two months after application and lasting up to a year. Rx–Rx On the basis of the current evidence, although PRP injections have been demonstrated to more effectively reduce pain and improve overall physical function compared with control studies, the quality of evidence is lacking, and further research is required to establish the efficacy of using PRP as a treatment option.
Glucose Amaine with Chondroitin Sulphate – Glucosamine and chondroitin have been widely promoted as a treatment for OA. Glucosamine, an amino sugar, is thought to promote the formation and repair of cartilage. Chondroitin, a carbohydrate, is a cartilage component that is thought to promote water retention and elasticity and to inhibit the enzymes that break down cartilage. Both compounds are manufactured by the body. Glucosamine supplements are derived from shellfish shells; chondroitin supplements are generally made from cow cartilage.
Duloxetine – This antidepressant, which was evaluated for OA for the first time in these guidelines, may help with chronic pain. However, side effects like nausea, dry mouth, fatigue, constipation, and increased sweating may keep some people from taking it. Duloxetine is appropriate for people with OA of the knee and other joints. Whether people with knee-only OA and coexisting health conditions should take it is uncertain.
Capsaicin – This analgesic, which is derived from chili peppers, is better than a placebo at reducing pain, but it can cause side effects such as a burning sensation or skin redness. It’s appropriate for knee-only OA in people without existing health conditions, but uncertain in people with multi-joint OA and those with health conditions.
Opioid and narcotic analgesics – A review of 18 randomized controlled trials showed a significant reduction in pain and some improvement in physical function with the use of these strong pain relievers. However, these benefits were countered by significant side effects, including nausea, constipation, dizziness, sleepiness, and vomiting. Overall, about a quarter of patients treated with opioids—and particularly with strong drugs like oxycodone and oxymorphone—dropped out of studies because of side effects. The recommendation on both oral and patch forms of opioid pain relievers is “uncertain.”
Corticosteroid injections – Injecting corticosteroid compounds directly into affected joints can be useful for decreasing pain in the short term, although the effect tends to wear off after a few weeks. To maintain relief, you may need to have corticosteroid injections in the same joint every few months or use another treatment.
Hyaluronic acid injections – Hyaluronic acid is meant to supplement a natural substance that gives joint fluid its viscosity. Most of the studies conducted have been in patients with knee OA. Although the study outcomes differ, some do find the treatment relieves pain. Hyaluronic acid injections seem to reach their peak benefit 8 weeks after the shot is given, and the effect lasts for about 24 weeks. Side effects were minimal, including temporary pain and swelling at the injection site. Because of inconsistent study results, hyaluronic acid injections are “not appropriate” for people with OA of the hip and other joints, and “uncertain” for those with knee-only OA.
Risedronate (Actonel) – This bisphosphonate drug is better known for treating osteoporosis, but it may also reduce cartilage degeneration. More studies are needed to determine whether risedronate helps with symptoms, function, or OA disease progression. For now, the drug is deemed “not appropriate.”
Bracing – Knee braces are available for the treatment of medial compartmental osteoarthritis (arthritis on the inside of the knee joint). These braces work by unloading the medial (inside) portion of the knee. These braces need to be custom made and therefore can be expensive.
Duloxetine – Normally used as an antidepressant, this medication is also approved to treat chronic pain, including osteoarthritis pain.
Disease-modifying anti-rheumatic drugs (DMARDs) – are used to slow the progression of rheumatoid arthritis. Drugs like methotrexate, sulfasalazine, and hydroxychloroquine are commonly prescribed. In addition, biologic DMARDs like etanercept and adalimumab may reduce the body’s overactive immune response. Because there are many different drugs today for rheumatoid arthritis, a rheumatology specialist is often required to effectively manage medications.
Glucosamine and chondroitin sulfate – substances found naturally in joint cartilage, can be taken as dietary supplements. Although patient reports indicate that these supplements may relieve pain, there is no evidence to support the use of glucosamine and chondroitin sulfate to decrease or reverse the progression of arthritis.
Avocado-soybean unsaponifiables – This nutritional supplement — a mixture of avocado and soybean oils — is widely used in Europe to treat knee and hip osteoarthritis. It acts as an anti-inflammatory, and some studies have shown it may slow down or even prevent joint damage.
Alternative therapies – Many alternative forms of therapy are unproven but may be helpful to try, provided you find a qualified practitioner and keep your doctor informed of your decision. Alternative therapies to treat pain include the use of acupuncture and magnetic pulse therapy.
Your doctor may recommend surgery if your pain from arthritis causes disability and is not relieved with nonsurgical treatment. As with all surgeries, there are some risks and possible complications with different knee procedures. Your doctor will discuss the possible complications with you before your operation.
- Arthroscopy – During arthroscopy, doctors use small incisions and thin instruments to diagnose and treat joint problems. Arthroscopic surgery is not often used to treat arthritis of the knee. In cases where osteoarthritis is accompanied by a degenerative meniscal tear, arthroscopic surgery may be recommended to treat the torn meniscus.
- Cartilage grafting – Normal, healthy cartilage tissue may be taken from another part of the knee or from a tissue bank to fill a hole in the articular cartilage. This procedure is typically considered only for younger patients who have small areas of cartilage damage.
- Synovectomy – The joint lining damaged by rheumatoid arthritis is removed to reduce pain and swelling.
- Osteotomy – In a knee osteotomy, either the tibia (shinbone) or femur (thighbone) is cut and then reshaped to relieve pressure on the knee joint. Knee osteotomy is used when you have early-stage osteoarthritis that has damaged just one side of the knee joint. By shifting your weight off the damaged side of the joint, an osteotomy can relieve pain and significantly improve function in your arthritic knee.
- Total or partial knee replacement (arthroplasty) – Your doctor will remove the damaged cartilage and bone, and then position new metal or plastic joint surfaces to restore the function of your knee. (Left) A partial knee replacement is an option when damage is limited to just one part of the knee. (Right) A total knee replacement prosthesis.
Surgical Treatment Options
Unicompartmental knee arthroplasty (UKA)
Total knee arthroplasty (TKA)
A high tibial osteotomy (HTO) may be indicated for unicompartmental knee osteoarthritis associated with malalignment. Typically an HTO is done for varus deformities where the medial compartment of the knee is worn and arthritis. The ideal patient for an HTO would be a young, active patient in whom arthroplasty would fail due to excessive component wear. An HTO preserves the actual knee joint, including the cruciate ligaments, and allows the patient to return to high-impact activities once healed. It does require additional healing time compared to an arthroplasty, is more prone to complications, depends on bone and fracture healing, is less reliable for pain relief, and ultimately does not replace cartilage that is already lost or repair any remaining cartilage. An osteotomy will delay the need for arthroplasty for up to 10 years.
Indications for HTO
Young (less than 50 years old), active patient
Healthy patient with good vascular status
Pain and disability interfering with daily life
Only one knee compartment is affected
A compliant patient who will be able to follow the postoperative protocol
Contraindications for HTO
Knee flexion contracture greater than 15 degrees
Knee flexion less than 90 degrees
If the procedure will need greater than 20 degrees of deformity correction
A UKA also is indicated in unicompartmental knee osteoarthritis. It is an alternative to an HTO and a TKA. It is indicated for older patients, typically 60 years or older, and relatively thin patients; although, with newer surgical techniques the indications are being pushed.
Indications for UKA
Older (60 years or older), lower demand patients
Relatively thin patients
Contraindications for UKA
Fixed varus deformity greater than 10 degrees
Fixed valgus deformity greater than 5 degrees
Arc of motion less than 90 degrees
Flexion contracture greater than 10 degrees
Arthritis in more than one compartment
Younger, higher activity patients or heavy laborers
A TKA is the surgical treatment option for patients failing conservative management and those with osteoarthritis in more than one compartment. It is regarded as a valuable intervention for patients who have severe daily pain along with radiographic evidence of knee osteoarthritis.
Indications for TKA
Symptomatic knee OA in more than one compartment
Failed non-surgical treatment options
Contraindications for TKA
Active or latent knee infection
Presence of active infection elsewhere in the body
Incompetent quadriceps muscle or extensor mechanism
Poor soft tissue coverage
Noncompliance due to major psychiatric disorder or alcohol or drug abuse
Insufficient bone stock for reconstruction
Poor health or presence of comorbidities that make the patient an unsuitable candidate for major surgery and anesthesia
Patient’s poor motivation or unrealistic expectations
Severe peripheral vascular disease
Advantages of UKA vs TKA
Faster rehabilitation and quicker recovery
Less blood loss
Preservation of normal kinematics
Less postsurgical pain and shorter hospital stay
Advantages of UKA vs HTO
Faster rehabilitation and quicker recovery
Higher initial success rate
Fewer short-term complications
Easier to convert to TKA
Straightening the knee against resistance will strengthen the quadriceps muscles at the front of the thigh. This can be achieved in a number of ways, including using ankle weights and resistance machines. One of the easiest ways involves using a resistance band
- The patient sits on a chair with one end of the band tied around their ankle and the other end around one of the chair legs.
- The band should be taut when the knee is bent at 90 degrees. The patient straightens the knee before slowly bending it and returning the foot back to the floor.
- Perform 10-15 repetitions and repeat this 2-3 times.
Still using the resistance band
- The patient lies on the floor with the band tied around one ankle and the other end attached to something sturdy, close to the floor. The band should be taught when the knee is straight
- The patient bends the knee to bring the heel towards the buttock as far as possible, and then slowly straightens the knee back again.
- Perform 10-15 repetitions and repeat this 2-3 times.
Calf raises are good for strengthening the Gastrocnemius muscle which is one of the two main calf muscles, but the only one which crosses the knee joint.
- The patient stands with the feet should width apart and close to a wall or chair which can be held for balance if required.
- The patient rises up on to the toes, keeping the knees straight, before slowly lowering the heels back to the floor.
- Perform 10-15 repetitions and repeat this 2-3 times.
- This exercise can be progressed by performing on one leg only.
Squats are really good exercises for strengthening all the main muscle groups of the legs and buttocks. They can start off as very shallow movements and progress until the knees reach a 90-degree angle at which point weights can be added.
- The patient stands with the feet shoulder width apart and backs straight.
- The knees are then bent as if trying to sit on a chair.
- The back should remain straight and the knees should not move forward past the toes.
- Perform 10-15 repetitions and repeat this 2-3 times.
- It uses fine needles to stimulate specific body areas to relieve pain or temporarily numb an area. Although it is used in many parts of the world and evidence suggests that it can help ease the pain of arthritis, there are few scientific studies of its effectiveness. Be sure your acupuncturist is certified, and do not hesitate to ask about his or her sterilization practices.
- Magnetic pulse therapy – is painless and works by applying a pulsed signal to the knee, which is placed in an electromagnetic field. Like many alternative therapies, magnetic pulse therapy has yet to be proven.
As with other arthritic conditions, initial treatment of arthritis of the knee is nonsurgical. Your doctor may recommend a range of treatment options.
Some changes in your daily life can protect your knee joint and slow the progress of arthritis.
- Minimize activities that aggravate the condition, such as climbing stairs.
- Switching from high impact activities (like jogging or tennis) to lower impact activities (like swimming or cycling) will put less stress on your knee.
- Losing weight can reduce stress on the knee joint, resulting in less pain and increased function.
- Physical therapy – Specific exercises can help increase the range of motion and flexibility, as well as help strengthen the muscles in your leg. Your doctor or a physical therapist can help develop an individualized exercise program that meets your needs and lifestyle.
- Assistive devices – Using devices such as a cane, wearing shock-absorbing shoes or inserts, or wearing a brace or knee sleeve can be helpful. A brace assists with stability and function and may be especially helpful if the arthritis is centered on one side of the knee. There are two types of braces that are often used for knee arthritis: An “unloader” brace shifts weight away from the affected portion of the knee, while a “support” brace helps support the entire knee load.
- Occupational therapy – An occupational therapist can help you discover ways to do everyday tasks or do your job without putting extra stress on your already painful joint. For instance, a toothbrush with a large grip could make brushing your teeth easier if you have finger osteoarthritis. A bench in your shower could help relieve the pain of standing if you have knee osteoarthritis.
- Other remedies – Applying heat or ice, using pain-relieving ointments or creams, or wearing elastic bandages to provide support to the knee may provide some relief from pain.
- Aerobic exercise – programs may make OA patients feel better, help reduces the joint pain, and make it easier for them to perform daily tasks. Exercise programs under medical supervision should be balanced with rest and joint care.[Rx] Aerobic programs truly border both clinical (rehabilitation) and home programs. Regardless of the setting, this program type was found to be effective for reducing pain in the hip and knee.[Rx] Patients are typically recommended to exercise between 50% and 70% target heart rate for a minimum of 30 min, 3 times a week, for overall weight management, health benefits, and a reduction in pain which was noted after a 6-month program.[Rx]
- Hydrotherapy (balneotherapy) – involves the use of water in any form or at any temperature (steam, liquid, ice) for the purpose of healing. In aquatic physical therapy or hydrotherapy, exercise activities are carried out in heated pools by a variety of providers.[Rx] Hydrotherapy/balneotherapy and aquatic therapy displayed positive results when conducted for testing a subject’s strength and flexibility. The results emphasized the role of these therapies in aiding normal walking and relieving joint pain.[Rx] The sessions typically are run from 6 to 48 weeks for the duration of 60 min and are conducted in a shallow pool with water temperatures ranging from 29°C to 34°C.[Rx]
Natural Relief From Arthritis Pain
- Arthritis is a painful and degenerative condition marked by inflammation in the joints that causes stiffness and pain. Osteoarthritis, the most common type of arthritis, gets worse with age and is caused by wear and tear over the years.
- Doctors traditionally treat arthritis with anti-inflammatory medications and painkillers. However, some medications cause side effects, and a natural approach to pain relief is becoming more popular. Remember to consult your doctor before trying these natural remedies.
- You do feel as if you are on your own, but with being part of the group you know you are not and it is very helpful to get thoughts and ideas from others who are suffering the same pain as you. “
- Your weight can make a big impact on the amount of pain you experience from arthritis.
- Extra weight puts more pressure on your joints—, especially your knees, hips, and feet. Reducing the stress on your joints by losing weight will improve your mobility, decrease pain, and prevent future damage to your joints.
Get More Exercise
- There are more benefits to exercise than just weight loss. Regular movement helps to maintain flexibility in your joints. Weight-bearing exercises like running and walking can be damaging. Instead, try low-impact exercises like water aerobics or swimming to flex your joints without adding further stress.
Use Hot and Cold Therapy
- Simple hot and cold treatments can make a world of difference when it comes to arthritis pain. Long, warm showers or baths—especially in the morning—help ease stiffness in your joints. Use an electric blanket or heating pad at night to keep your joints loose and use moist heating pads.
- Cold treatments are best for relieving joint pain. Wrap a gel ice pack or a bag of frozen vegetables in a towel and apply it to painful joints for quick relief
Use Meditation to Cope With Pain
- Meditation and relaxation techniques may be able to help you reduce pain from arthritis by reducing stress and enabling you to cope with it better. According to the National Institutes of Health (NIH), studies have found that the practice of mindfulness meditation is helpful for some people with painful joints. Researchers also found that those with depression and arthritis benefitted the most from meditation.
Include the Right Fatty Acids in Your Diet
- Everyone needs omega-3 fatty acids in their diets for optimum health. However, these fats may also help your arthritis. Fish oil supplements, which are high in omega-3s, may help reduce joint stiffness and pain.
- Another fatty acid that can help is gamma-linolenic acid or GLA. It’s found in the seeds of certain plants like evening primrose, borage, hemp, and black currants. You can also buy the oils of the seeds as a supplement. However, be sure to check with your doctor before taking them.
Turmeric to Dishes
- Turmeric, the yellow spice common in Indian dishes, contains a chemical called curcumin that may be able to reduce arthritis pain. The secret is its anti-inflammatory properties.
- The NIH reports that turmeric given to lab rats reduced inflammation in their joints. Research on humans is scarce, but it can’t hurt to add this tasty spice to your dinners.
- According to the Arthritis Foundation, regular massaging of arthritic joints can help reduce pain and stiffness and improve your range of motion. Work with a physical therapist to learn self-massage, or schedule appointments with a massage therapist regularly
- Your massage therapist should be experienced with working on people who have arthritis. Check with your doctor for a recommendation.
Consider Herbal Supplements
- There are many kinds of herbal supplements on the market that claim to be able to reduce joint pain. Some of the herbs touted for arthritis pain include boswellia, bromelain, devil’s claw, ginkgo, stinging nettle, and thunder god vine.
- Always talk to your doctor before trying a new supplement to avoid side effects and dangerous drug interactions.
Homeopathic medicines for Osteoarthritis
- Bryonia Alba – The excellent remedy which is useful in the treatment of osteoarthritis, pain with inflammation which is aggravated by movement and relieved by moderate pressure and rest. There is inflammation of joints which are hot and swollen.
- RhusToxm – Recurring attacks due to getting chilled. Rheumatism caused by damp weather and worse in damp climate; there is restlessness and the pains are worse on first motion, better by continued motion
- Kali Carb – pains stitching, stabbing and burning character relieved temporarily by cold application and not by rest or motion. The patient shrieks on account of pain. Backache accompanied by great weakness
- Arnica – Chronic arthritis with a feeling of bruised soreness can indicate a need for this remedy. Pain is worse from touch and may occur in joints that were injured in the past.
- Ruta graveolens – Arthritis with a feeling of great stiffness and lameness, worse from cold and damp, and worse from exertion often is relieved by this remedy. Tendons and the capsules of the joints may be affected. Arthritis may have developed after overuse, from repeated wear and tear.
- Kalmia latiflora – Intense arthritic pain that appears quite suddenly may indicate this medicine—especially when the problems start in higher joints and extend to lower ones. Pain and inflammation often start in the shoulder, moving to the elbow, wrist, and hand. The knees are also frequently affected. Discomfort is worse from motion and often worse at night.
- Apismellifica – This remedy can be helpful in acute conditions with redness, tenderness, and swelling. Joints feel hot and have stinging pain. The hands and knees are often affected. Warmth can aggravate the symptoms and cool applications bring relief.
- Calcarea fluorica – This medicine is often indicated for arthritic pains that are improved by heat and motion. Joints become enlarged and hard, and nodosities or bone spurs may develop. Arthritis after a chronic injury to joints often responds to Calcarea fluorica.
- Calcarea carbonica – This remedy is often useful for arthritis in a person who is flabby or overweight, and easily tired by exertion. Inflammation and soreness are worse from cold and dampness, and weakness or cramping in the extremities are often seen. Problems often focus on the knees when Calcarea is needed.
- Sticta Pulmonaria – Rheumatism of right shoulder blade or joint, wrist joint, ankle joint and knee joint. It also reduces fluid in the joints.
