ABSTRACT:
A roller bearing knee replacement joint is provided in which a femoral component attached to the surgically prepared distal femur is positioned for articulation on a tibial component, which simulates the articulating surface of the natural tibia. The articulating surface has replaceable roller bearing units which provide the contact with the femoral component. A bearing mounting member has spaced bearing unit receptacles which are adapted to receive the bearing units laterally and permit the lateral removable therefrom. The roller bearing units reduce friction between the components and may be replaced with less extensive surgical procedures than in other replacement procedures. A patella component has a patella button which rides in a central concave groove in the femoral component and is mounted on radial roller bearings to provide rotational movement for the patella button to emulate the motion of a natural patella.
