Knee Bursitis

Knee Bursitis is inflammation of a bursa, a small, fluid-filled, pad-like sac that cushions pressure between bones and tendons and muscles near the knee joint. Knee Bursitis commonly occurs over the kneecap or on the inner side of the knee below the joint, often causing pain and limiting mobility.
