Abstract
A knee endoprosthesis for total knee arthroplasty has a femur bearing surface and a tibia bearing surface. The femur bearing surface has a medial surface and a lateral surface. The tibia bearing surface has a concave medial shell and a concave lateral shell and is configured for sliding on the femur bearing surface. The medial and lateral shells form an asymmetric surface. The medial and lateral surfaces form a non-asymmetric or quasi-symmetric bearing surface. The medial and lateral surfaces coincide in an anterior femur condylar radius. The tibia bearing surface forms an anterior contour portion with an anterior point and a posterior contour portion with a posterior point. The anterior point is proximally elevated relative to the posterior point. A portion of the anterior portion at the medial shell forms an antero-medial apex point. An inlay can be arranged at the tibia part.
