What causes knee pain? (Continued)

Medical conditions

Rheumatoid arthritis is an autoimmune condition that can affect any joint in the body. It can cause severe pain and disability, as well as swelling.

Gout is a form of arthritis that is most commonly found in the big toe, though it can also affect the knee.

With septic arthritis (infectious arthritis), the knee joint can become infected; this leads to pain, swelling, and fever. This condition requires antibiotics and drainage treatments as soon as possible.

Chronic use/overuse conditions

Patellar tendinitis is an inflammation of the tendons connecting the kneecap (patella) to the bone of the lower leg. Patellar tendinitis is a chronic condition often found in individuals repeating the same motion (such as runners and cyclists).
