Abstract

A knee joint prosthesis includes tibial and femoral components and a bearing insert designed for unicompartmental prosthetic total knee replacement and can be implanted using arthroscopic surgical techiques. The tibial and femoral prosthesis components have channels or portals therethrough allowing supply of cement to the prosthesis-bone interface after the prosthesis has been positioned for implant. Recesses communicate with the channels and cooperate with the bone surfaces to form cement receiving chambers, and rims at least partially surround the recesses to penetrate the bone surfaces to stabilize the positions of the prostheses and form seals preventing cement from escaping from the prosthesis-bone interfaces.
