Artificial joint, used as endoprosthesis for human knee joint, comprises a first joint compartment and a second joint compartment having contact surfaces arranged at an angle so that their surface normals have a common intersection

摘要

Artificial joint (1) comprises a first joint compartment (2) formed by a first joint head (3) and a first joint cavity (4), and a second joint compartment (5) formed by a second joint head (6) and a second joint cavity (7). Two contact surfaces (C) of the joint compartments have an offset in a main function plane. The contact surfaces are arranged at an angle depending on a bending angle so that the surface normals (8, 9) of the contact surfaces have a common intersection at each bending angle. The contact surfaces rise toward the middle of the joint. The contact surfaces have a different angle of incline.
