Abstract:
1. A prosthetic knee implant system comprising: a distal femoral implant component having a medial condyle, a lateral condyle and a cam between the condyles; a tibial tray; a mobile bearing tibial tray insert including a medial condyle receiver spaced apart from a lateral condyle receiver; the tibial tray and mobile bearing tibial tray insert including a complementary recess and projection sized and shaped for rotational mounting of the mobile bearing tibial tray insert on the tibial tray; the mobile bearing tibial tray insert also including a stabilizing post positioned to engage the cam of the distal femoral implant component during articulation; and wherein the mobile bearing tibial tray insert has a medial-lateral centerline, the stabilizing post has a medial-lateral centerline offset medially from the medial-lateral centerline of the mobile bearing tibial tray insert, and the complementary recess and projection define a substantially vertical rotational axis offset laterally from the medial-lateral centerline of the stabilizing post.
