Coloured X-rays (front and side views) of the knee joint of a patient aged 81, showing femoro-patellar osteoarthritis. The disease of arthritis has affected the patella (knee-cap) and its joint with the femur (thigh-bone) reducing the space between them. At far right, the presence of calcification (white structures) in the femoro-popliteal artery of the leg is seen which causes inflammation of the artery (arteritis).
