Abstract
The present invention relates to prosthetic knee devices providing for an expanded range of translational movement without substantially reducing the risk of inadvertent dislocation of the knee when implanted. The devices of the invention achieve the expanded range of motion without requiring a substantial posterioral shifting of the points of contact between the femoral and tibial components. The prostheses of the invention also reduce the risk of breakdown of the plastic components of the prosthesis and the underlying resectioned proximal tibia surface by providing an expanded, winged fixation post.
