1. A method of carrying out a surgical procedure on a knee of a leg of a patient, comprising:
obtaining anatomical data for the leg of the patient, wherein the anatomical data allows a femoral mechanical axis, a tibial mechanical axis, and a joint line of the knee to be determined,
setting a range for a final long leg angle between the tibial mechanical axis and the femoral mechanical axis,
setting boundaries for a final proximal tibial cut angle,
determining a long leg angle between the tibial mechanical axis and the femoral mechanical axis from the anatomical data,
setting a planned distal femoral cut angle to make a final planned joint line equal to the joint line determined from the anatomical data,
setting a planned proximal tibial cut angle to adjust the long leg angle to a final planned long leg angle within the range for the final long leg angle,
determining whether the planned proximal tibial cut angle is within the boundaries for the final proximal tibial cut angle,
setting the planned proximal tibial cut angle as a final planned proximal tibial cut angle when the planned proximal tibial cut angle is within the boundaries for the final proximal tibial cut angle,
setting the planned distal femoral cut angle as the final planned distal femoral cut angle when the planned proximal tibial cut angle is within the boundaries for the final proximal tibial cut angle, and
carrying out a surgical procedure on the knee of the patient, wherein a distal femoral cut is made along a planned femoral cut line using the final planned distal femoral cut angle and a proximal tibial cut is made along a planned tibial cut line using the final planned proximal tibial cut angle, the planned femoral cut line being not parallel with the planned tibial cut line.
