ABSTRACT:
A knee prosthesis includes a femoral prosthetic part which forms a pair of condylar gliding surfaces, a tibial part that has tibial gliding surfaces cooperating with the condylar gliding surfaces and a coupling part that connects the femoral and tibial parts so that they can rotate about a rotational axis that is approximately parallel to the axis of the tibia. If the femoral and tibial parts have the same anteroposterior alignment, an applied load is borne by a central region of the tibial gliding surfaces. The tibial gliding surface slopes upwardly relative to the prosthesis both in front of and behind the central region of the tibial gliding surface so that when the femoral and tibial parts rotate against one another, each of the condylar gliding surfaces remains in contact with its corresponding tibial gliding surface.
