Definition

Knee bursitis is inflammation of a bursa located near your knee joint. A bursa is a small fluid-filled, pad-like sac that reduces friction between moving parts in your knee — bone and skin, bone and muscle, bone and tendons, or tendons and muscles.

If you have knee bursitis, one or more of the 11 bursae associated with each of your knees may be inflamed. Knee bursitis causes pain and can limit your mobility.

Treatment for knee bursitis often includes a combination of self-care practices and doctor-administered treatments to alleviate pain and inflammation.
