Claim 0:
1. A knee joint prosthesis system for implantation in a first knee joint of a patient, the first knee joint comprising a femur and a tibia, the first knee joint having a condition, wherein the first knee joint is on a first side of the patient, selected from a right side and a left side, and is not on a second side of the patient, the second side comprising the other of the right side and the left side, the knee joint prosthesis system comprising:
a tibial baseplate component configured to be implanted on the tibia, the tibial baseplate component comprising an insert interface;
a femoral component configured to be implanted on the femur, the femoral component comprising a femoral articulation surface; and
a tibial insert comprising a baseplate interface attachable to the insert interface of the tibial baseplate component, the tibial insert comprising a tibial articulation surface configured to articulate with the femoral articulation surface;
wherein:
the tibial articulation surface comprises a medial tibial compartment and a lateral tibial compartment that is asymmetrical to the medial tibial compartment;
the tibial articulation surface is shaped to cooperate with the femoral articulation surface to adapt kinematics of the first knee joint having the condition;
the tibial articulation surface is suitable for implantation in a second knee joint on the second side, the second knee joint lacking the condition; and
one of the following is true:
the tibial articulation surface facilitates tibiofemoral rotation within the medial tibial compartment during flexion of the first knee joint where the condition is a valgus knee joint; and
the tibial articulation surface adjusts mediolateral stability during flexion of the first knee joint where the condition is a varus knee joint.
