Anterior femoral offset is a flawed measurement of patellofemoral overstuffing
On a true lateral X-ray, the trochlea's MAP omits the trochlear groove. Because the patella primarily articulates with the trochlear groove and because the relationship between the MAP and the trochlear groove is variable depending on the knee flexion angle, any conclusions regarding overstuffing based on a postoperative lateral knee X-ray are flawed.
