Claim One:
1. A prosthesis for replacement of a least part of a knee joint in a leg, the leg including a femur and a tibia, the prosthesis comprising: a femoral component adapted to fit on a distal end of the femur, the femoral component comprising: a lateral condylar structure defining a lateral condylar bearing surface; and a medial condylar structure defining a medial condylar bearing surface; a tibial component adapted to fit on a proximal end of the tibia, the tibial component comprising: a medial portion comprising a medial bearing surface configured to articulate with the medial condylar bearing surface when the prosthesis is installed and a lateral portion comprising a lateral bearing surface configured to articulate with the lateral condylar bearing surface when the prosthesis is installed, wherein: the medial bearing surface comprises an anterior-most edge and a posterior-most edge; the lateral bearing surface comprises an anterior-most edge and a posterior-most edge; the medial bearing surface has a minimum thickness that is thicker in a superior-inferior direction at the medial bearing surface posterior-most edge than a minimum thickness of the lateral bearing surface at the lateral bearing surface posterior-most edge; and the medial bearing surface has a minimum thickness that is thinner in a superior-inferior direction at the medial bearing surface anterior-most edge than a minimum thickness of the lateral bearing surface at the lateral bearing surface anterior-most edge.
