A femur slide has a patella shield and two convex curved condyle cups which are anteriorly rigidly joined by the patella shield. The two condyle cups and the patella shield define internally anterior and posterior matching surfaces which correspond with a femural ventral cut and with a femural dorsal cut. Relative to a reference plane which is defined by posterior slide surfaces of the condyle cups, an anterio-medial matching surface lies nearer to the reference plane than an anterio-lateral matching surface. The anterior matching surfaces are defined by a slanted surface with is continuously slanted in a direction from lateral to medial to posterior, and an angle between the slanted surface and the reference plane lies between three and ten degrees.
