Rheumatoid Arthritis of the Knee

Rheumatoid arthritis (RA) can affect your knees and any other joint in your body. It’s an immune system disorder in which the body attacks itself, and especially the joints. Doctors don’t know exactly what causes it.

Symptoms of rheumatoid arthritis include pain, swelling, inflammation, stiffness, and warmth around the knees.

Treatment options for rheumatoid arthritis include rest, exercise and medication.
