Abstract

A knee joint endoprosthesis is provided having a femoral part (1) that can be linked with a shank part to be anchored in the femur, the femoral part being provided with two runners (2, 3) interlinked ventrally via a bridge. A tibia plateau part (5) interacts with a shank part to be anchored in the tibia and is provided with two slide guides (6) in which the runners (2, 3) of the femoral part (1) can roll off and slide. With increasing bend of the knee joint and upon exceeding a predetermined bending angle, the femoral part is allowed to perform an increasing rotation relative to the tibia plateau part (5).
