ABSTRACT:
According to one embodiment, a method for determining a joint line position includes: providing a femoral trial component, the femoral trial component comprising an anterior flange and at least one mark on the anterior flange of the femoral trial component to indicate a desired patellofemoral contact point in extension; referencing the mark on the femoral trial component during a surgical procedure to assist in determining a proper superior-inferior joint line position between a tibial prosthetic component and a femoral prosthetic component; installing the femoral prosthetic component based at least in part on the determination of the proper superior-inferior joint line position between the tibial component and the femoral component; installing the tibial prosthetic component based at least in part on the determination of the proper superior-inferior joint line position; and completing the surgical procedure with the femoral component and tibial component in proper position is described.
