PES ANSERINE BURSITIS
- Inflammation of the bursa (sack of fluid), which lies between the tendons on the inner (medial) side of the knee and the proximal (upper) tibia. (See illustration).
MECHANISM OF INJURY / HOW IT OCCURS:
- A result of overuse and friction causing an increase in fluid formation in the bursa.
- Often seen in runners and cyclists.
- Individuals will complain of pain at inner knee region approximately 2-3 inches below the joint line.
- Symptoms aggravated with activity
- Physical examination reveals tenderness over bursa.
- May detect swelling.
- Radiographic studies may be considered to rule out stress fracture.
- Rest, ice, and anti inflammatory medications (NSAIDs) are initial treatment modalities.
- A cortisone injection may be considered by a physician, especially if symptoms persist.
- Cross training while recovering from injury.
- Cyclists may need to adjust their cleat position to avoid external rotation of the tibia. (See bicycle set up recommendations).
