Claim 11:
12. 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 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;
a right side tibial insert attachable to the insert interface of the tibial baseplate component, the right side tibial insert comprising a tibial articulation surface configured to articulate with the femoral articulation surface and rotate the tibia about a longitudinal axis of the tibia passing through a medial tibial compartment of the right side tibial insert during flexion or extension of a right side knee joint;
a left side tibial insert attachable to the insert interface of the tibial baseplate component, the left side tibial insert comprising a tibial articulation surface configured to articulate with the femoral articulation surface and rotate the tibia about the longitudinal axis passing through a medial tibial compartment of the left side tibial insert during flexion or extension of a left side knee joint; and
wherein:
the tibial articulation surface of the right side tibial insert 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 insert 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.
