ABSTRACT:
The femur part is made for clamping to the end of a femur bone in the manner of a "clamp strap". The femur part includes a backwall having a convex outer surface facing a patella shield which is likewise provided with a facing convex surface. The vertex lines of the respective surfaces define a wedge angle which permits the femur part to be clamped to the femur bone. In addition, the vertex lines of the two surfaces are located in a common connecting plane which is perpendicular to the respective tangential planes passing through the vertex lines. The wedge angle may extend up to 30.degree..
