Claim 20:
21. A knee joint prosthesis system for implantation in a knee joint of a patient, the knee joint comprising a femur and a tibia, the knee joint having a condition, wherein the 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 femoral component configured to be implanted on the femur, the femoral component comprising a femoral articulation surface;
a right side tibial component attachable on the tibia, the right side tibial component comprising a tibial articulation surface configured to articulate with the femoral articulation surface and rotate the tibia about a longitudinal axis passing through a medial tibial compartment of the right side tibial component during flexion or extension of a right side knee joint;
a left side tibial component attachable on the tibia, the left side tibial component comprising a tibial articulation surface configured to articulate with the femoral articulation surface and rotate the tibia about a longitudinal axis passing through a medial tibial compartment of the left side tibial component during flexion or extension of a left side knee joint; and
wherein:
the tibial articulation surface of the right side tibial component is shaped to cooperate with the femoral articulation surface to change kinematics of the knee joint having the condition if the knee joint comprises the left side knee joint; and
the tibial articulation surface of the left side tibial component is shaped to cooperate with the femoral articulation surface to change kinematics of the knee joint having the condition if the knee joint comprises the right side knee joint.
