摘要： An artificial knee joint comprise a femoral component and tibial component. The posterior side of the femoral component comprises medial and lateral condyles, wherein the width and offset of the posteromedial condyle is greater than the width and offset of the posterolateral condyle. At the posterior the tibial bearing component comprises medial and lateral articulating surface geometries, wherein the posterior slope of the lateral articulating geometry is greater than the posterior slope of the medial articulating geometry. The medial articulating surface geometry of the tibial bearing component supports the medial condyle of the femoral component and the lateral articulating surface geometry of the tibial bearing component supports the lateral condyle of the femoral component. The greater slope of the lateral articulating geometry allows the femoral component condyle to roll down to the posterior during knee flexion. This invention of an artificial knee joint for a prosthetic knee implant system facilitates deep knee flexes beyond 130 degrees.
