Knee

Bursa in the knee

Because bursae are located in prominent and exposed positions, the pain of bursitis may be exquisite, and point tenderness is typical. Other features of bursitis may include swelling and erythema, particularly with more superficial bursae. Active range of motion is often decreased or painful, but passive motion is usually normal as it results in less pressure on the inflamed bursa.
