摘要
A method for improved rotational alignment of the bones in joint surgery is described. The method involves the tracking of the relative motion of a third bone in with respect to the movement of the first and second bone. In one aspect of the invention, the motion of the patella is used to derive the axis of rotation of the femoral and tibial components in total knee arthroplasty, either alone or in combination with other techniques.
