Abstract: The invention relates to a knee endoprosthesis comprising a femoral component (1) which has two condylar surfaces (1a, 1b) for anchoring on the distal femur, comprising a tibial component (2) for anchoring on the proximal tibia, and comprising sliding surfaces between the two components (1, 2). It is proposed according to the invention that the entire femoral component (1), but at least its condylar surfaces (1a, 1b) are made of a solidly sintered ceramic for articulation with the tibial component (2), so that the knee endoprosthesis will have the least possible amount of abrasion with optimal reproduction of the anatomical and kinematic properties of the natural knee joint, in particular through suitable combinations of materials and by reducing the abrasion-generating surfaces.
