Abstract:
A condylar total knee replacement prosthesis which comprises:(a) a femoral component adapted to be fixed to the femur and having a pair of femoral condylar surfaces;(b) a tibial component adapted to be attached to the tibia and having a tibial platform; and(c) a mobile bearing component which is interposed between each condylar surface and the tibial platform and which has dished bearing surfaces adapted to support and conform with the corresponding femoral condylar surfaces, the mobile bearing component being slidable on the tibial platform in the anterior/posterior direction;said femoral component having an intercondylar guide surface which is adapted to engage a corresponding tibial guide surface which is fixed on the tibial platform or is integral therewith, the intercondylar guide surface being rounded and having a center of curvature when viewed sagitally, which is offset from a major center curvature of the femoral condylar surfaces.
