The present invention relates to a femoral component for use in connection with knee anthroplasty. The implant includes a support having a contoured inner bone engaging surface, and a shell affixed to the support. The shell has an outer surface spaced so as to provide an articulation surface for engaging the tibia that substantially replicates the shape of a femoral condyle, and an inner surface for receiving an outer surface of the support. The support bone engaging surface is structured to mate with a prepared surface of the distal femur and the support spaces the shell outer surface at a predetermined distance from the prepared surface.
