  • Mobile bearing knee with metal on metal interface
    Patent number: 5957979
    Abstract: In the subject invention, the articulating component includes a metal tray and a polyethylene bearing molded or otherwise connected to the metal tray. The distal surface of the metal tray, the surface in contact with the tibial component, is highly polished and is substantially flat. The proximal surface of the tibial component, the surface in contact with the articulating component, is likewise highly polished and substantially flat. In use, the two highly polished flat surfaces provide an environment wherein the articulating surface may freely move relative to the tibial component as the patient's knee joint is flexed and extended during movement.
