Rheumatoid arthritis. Three-dimensional computer graphic representation of the human knee, showing red painful areas caused by rheumatoid arthritis. Muscles, tendons and bones of the knee are seen. The femur or thigh bone (at top) articulates with the tibia or shin bone (at bottom) at the knee joint. In rheumatoid arthritis of the knee, the region of pain is concentrated at the joint where there is most stress due to movement. Rheumatoid arthritis (joint inflammation) may affect joints of the fingers, knees, wrists, feet, ankles, hips or shoulders. It is an autoimmune disorder where the body's own defence system attacks tissues. Anti-inflammatory drugs reduce pain and stiffness.
