摘要:
The invention relates to a femoral component (1) of a knee replacement assembly. The knee replacement assembly is arranged to articulate about an articulation axis (X). The femoral component comprises an outer surface (100), wherein the outer surface is arranged to define a replacement condyle; and an inner surface (200), opposed to the outer surface, wherein the inner surface is adapted for attachment to a prepared distal femur. The inner surface comprises portions (210, 220, 230, 240) provided with mutually-parallel ridges (201) and grooves (202). The ridges and grooves are arranged to provide an increased or reduced stiffness of the femoral component when cantilevered about the articulation axis compared with a stiffness of the femoral component when cantilevered about a transverse axis.
