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.
