Knee bursitis is a condition characterized by inflammation of the bursae, the small fluid-filled sacs that cushion the knee joint. It can be caused by overuse, direct trauma, or infection. Symptoms of knee bursitis include swelling, pain, and warmth around the affected area. Treatment options typically involve resting the knee, applying ice packs, and taking nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. In some cases, aspiration of fluid from the bursa or corticosteroid injections may be necessary. Physical therapy can also help improve strength and flexibility in the knee.
