Pes Anserine Bursitis, or Knee Tendon Bursitis, refers to an inflammation of the bursa on the inner side of the knee. The bursa is a lubricating sac located between the shinbone and hamstring tendons that prevents the two structures from rubbing against each other. The condition occurs when the bursa produces excess fluid and becomes inflamed, thereby placing pressure on the adjacent parts of the joint. Certain factors may increase a person’s susceptibility to develop Pes Anserine Bursitis. These are:
- Sports activities like running and swimming
- Old age
- Medical conditions such as Knee Osteoarthritis or Medial Meniscus Tear
- Improper training techniques
- Running uphill
- Sudden increase in running distance
- Tight hamstrings
- Trauma or contusion to the inner part of the knee
- Outward turning of the lower leg due to Flat Feet or Knock Knees
- Forceful twisting with the foot planted on the ground
- Repetitive activities
- Pain at the inner part of the knee
- Tenderness to touch
- Difficulty bending or straightening the knee
- Pain may increase while exercising, climbing stairs or any other stressful activity
- Limited range of motion
The orthopedic doctor may physically examine the knee and check for tightness in hamstring muscles. He may inquire about the patient’s medical history and nature of activities performed on a daily basis. An X-ray may be conducted to rule out a stress fracture. CT scan or MRI may be required to assess damage to the medial compartment of the knee. The doctor may take a sample of bursa fluid to be tested in case infection is suspected.
- Rest: The patient may be advised to take rest for a few days and avoid any activities that may aggravate the pain.
- Ice pack: Application of ice packs at frequent intervals may reduce swelling and stiffness.
- Medications: The orthopedic doctor may prescribe anti-inflammatory medications to provide relief from pain. Antibiotics may be prescribed in case of infection of septic bursitis.
- Injections: Injecting steroid mediations directly into the joint may be suggested in case of severe pain and swelling.
- Physical therapy: Performing light stretching exercises may help to release stiffness and strengthen the hamstring muscles.
- Surgery: In case the symptoms do not subside, the doctor may recommend surgical removal of the bursa.
- Lifestyle modification: Athletes may be suggested to reduce or alter their exercise programs to prevent the condition from recurring.
