<p>The present invention relates to an improved knee prosthesis, specifically designed for providing an optimum bone anchoring and articulation mobility. The subject prosthesis construction comprises a femural component, a tibial component and a patella component, and, for each said components, also individually considered, it comprises a hollow endomedular stub having transverse openings to allow the mentioned components to be anchored to the bone during the regrowth of the latter, both inside and outside of said endomedular stub, with a consequent formation of a mechanically stable bone grid. Moreover, the tibial component defines, at the top thereof, a sliding plane for two components supported on this sliding plane and provided, on an opposite side of said plane, a spherical cap concavity, which is coupled to the femural component, for association with the bottom end of the femur and having a corresponding configuration. <IMAGE></p> |
