The bursae of the knee are small fluid filled sacs that serve as shock absorbers between the muscles, tendons and skin of the joint and the adjacent bones. Knee bursitis is the medical condition that occurs when these sacs become inflamed. The usual causes of this condition are falling onto the knee, a direct blow to the joint or extended kneeling or squatting. Symptoms of knee bursitis are pain, swelling and unusual warmth of the skin over the knee joint, especially on its inner side. Treatment of knee bursitis may be less of a priority than symptom management, since the condition tends to resolve itself. However, options such as pain killers, knee pads and even corticosteroids may be considered if the condition is very painful.

To have your bursitis treated, you should visit a doctor. However, in most cases, the symptoms noted above will eventually disappear, so your doctor may focus on managing your pain rather than curing the condition in the normal sense.
