Claim 8:
9. The system for total knee replacement of claim 8:
wherein the intermediate femoral alignment guide defines a nominal geometry between the tibial side and the femoral side that approximates a first target geometry between an inner proximal tibial face of an artificial tibial component and an inner distal femoral face of an artificial femoral component when the artificial tibial component and the artificial femoral component are assembled and form the intermediate angle;
wherein the intermediate femoral alignment guide defines the second set of femoral pin guides at a first offset from the tibial side and the femoral side;
wherein the posterior femoral cut guide defines the posterior femoral cut plane at a second offset from the third set of pins when located on the femur; and
wherein a sum of the first offset and the second offset approximates relative positions of the inner proximal tibial face of the artificial tibial component, the inner distal femoral face of the artificial femoral component, and an inner posterior femoral face of the artificial femoral component when the artificial tibial component and the artificial femoral component form the intermediate angle to produce the target partial-flexion tension on the medial ligament and the lateral ligament with the artificial tibial component and the artificial femoral component installed in the knee and with the knee forming the intermediate angle.
