Abstract

A femoral component used in an artificial knee joint has an integral body provided with a lateral condyle protecting top, a medial condyle protecting top, and a condyle groove protecting edge. The lateral condyle protecting top and/or the medial condyle protecting top are provided respectively with at least one retaining slot or hooking eye in the outer side thereof. The retaining slot or hooking eye serves to enable the femoral component used in the artificial knee joint to work in combination with a femoral hipbone rehabilitating device, such as a bone plate.

Claims

1. An implantable femoral component of an artificial knee joint comprising:

a lateral condyle top portion;

a medial condyle top portion;

a condyle groove edge portion integrally interconnecting said lateral condyle top portion and said medial condyle top portion; and

means for coupling an elongated femoral bone rehabilitating plate adapted to be secured to a femur at a location spaced from the artificial knee joint to said femoral component, said coupling means including a pair of spaced retaining slots formed in one of said lateral and medial condyle top portions;

said implantable femoral component further comprising, in combination, an elongated femoral bone rehabilitating plate adapted to be secured to a femur at a location spaced from the artificial knee joint, said elongated femoral bone rehabilitating plate being provided with a coupling element attached to said coupling means.

2. The implantable femoral component of claim 1, wherein said coupling element in hook-shaped.
