Knee replacement surgery. Surgeon placing a cuff around a patient's upper thigh in preparation for total knee replacement surgery. During the operation prostheses will be implanted into the thigh bone (femur) and shinbone (tibia) to form an artificial knee joint. Knee joints need replacing when the protective cartilage that surrounds them is lost. Cartilage can be lost due to injury or osteoarthritis.
