Method and apparatus for locating functional structures of the lower leg during knee surgery

摘要

Method and apparatus for locating functional structures of the lower leg during knee implant surgery by determining the location of the weight-bearing axis. The functional center of the hip is located by fixing the acetabulum of the patient, rotating the femur about its head to several locations, measuring changes of position of a reference point on the femur and computing an imaginary sphere having a center corresponding to the location of the functional center of the hip.
