Abstract

A knee-joint endoprosthesis includes a metallic femoral part (2) anchored in the femur that articulates with a tibial part anchored in the tibia bone, the articulating surface of the femoral part (2) being a ceramic structural member (3) that is connected to the femoral part (2) in a mechanically stable manner. The attachment of the ceramic structural member (3) to the femoral part (2), can be accomplished by using a conical clamping device, by use of a fixing screw, by shrinking, soldering or welding it on, or by vapor deposition or spray application.
