Abstract:
1. A surgical method for implantation at an intersection of a femur, tibia and patella in a knee joint of a patient a partial or total knee prosthesis that includes at least a patellar implant and a femoral implant, the method comprising per-operatively performing the steps of: recording in a computer data relating to an anatomical geometry of the knee joint proximate the intersection of the femur, the tibia and the patella; identifying in the computer the partial or total knee prosthesis; displaying on a computer screen a virtual implantation of the patellar implant in the patella and the femoral implant in the femur; assessing on the computer screen congruency between the patellar implant and a prosthetic femoral trochlea on the femoral implant displayed in a transverse plane passing through both the patella and the prosthetic femoral trochlea; and recording in the computer a virtual implantation in the transverse plane of the patellar implant and the femoral implant.
