ABSTRACT:
Artificial joint, in particular an endoprothesis for the human knee joint, consisting of at least two joint parts moving with respect to each other, a joint head and a joint base, with toroidal joint surfaces, that have function surfaces with differing circular intersection contours in mutually perpendicular planes--a longitudinal plane and a transverse plane--whereby the curve ratios of the function surfaces are defined in each of the planes as either convex--convex, convex-concave, or concave--concave, and the joint geometry of the function areas to each other in each of the two planes is determined by a link chain with two link axes (dimeric link chain), which proceed through the rotation centers of the function areas with the radii of the attendant intersection contours, respectively.
