  • Knee prosthesis with a rotational plate
    Patent number: 7951204
    Abstract: The knee prosthesis with rotary plate comprises a metal base (2) and a tibia plate (3) which are equipped with guide means (22, 22?, 22?, 26, 29, 5, 6, 5?, 9, 50, 51, 52, 13, 15, 18; 34, 34?, 34?, 35, 37, 7, 8, 10, 12, 53, 54, 55, 10?, 17) defining a center of rotation (C,C?) which may be offset from that of the tibia bone axis (YY?), so as to allow the tibia plate (3) to slide in rotation over the said base, the said guide means being positioned a certain distance away from the center of rotation (C, C?).

  • Knee prosthesis with a rotational plate
    Patent number: 6299646
    Abstract: Knee prosthesis comprising a metal base secured to an anchoring rod for fixing it into a tibia of a patient. A plastic tibia plate is freely slidable over the base. The metal base and the tibia plate are equipped with a guide mechanism defining a center of rotation offset from that of a tibia bone axis, so as to allow the plate to slide in rotation over the base. The guide mechanism is positioned a given distance from the center of rotation. The metal base comprises an upstand in the shape of an arc of a circle having a central part secured to lateral edges which are shorter than the central part. The tibia plate comprises, on a lower face thereof, a housing in the shape of an arc of a circle.
