Abstract
The present invention is directed to prosthetic knee joints having femoral and tibial components. More particularly, in one embodiment the knee joint prosthesis of the present invention includes an auxiliary pair of load bearing surfaces in addition to other load bearing surfaces of the tibial and femoral components, which are the medial tibial and femoral condyles, the lateral tibial and femoral condyles, and the central tibial and femoral cam surfaces. The auxiliary pair of load bearing surfaces are located on the tibial component, posterior (i.e, on the rear side of the knee joint) to the central cam, centered between the tibial condyles, and on the femoral component, posterior to the femoral central camming surface, centered between the femoral condyles.
