Abstract
A prosthesis that replaces the articulating surfaces of the knee joint with mechanical devices which are designed to reproduce its function. A portion of the lower end of the femur is removed and replaced by a cap while the upper tibia is cut off and replaced by a tibial plateau. The articulating surface of the patella is modified to permit fixation of a third component which articulates with a groove in the anterior part of the femoral cap.
