Decision Making and Management of Anterior Knee Pain in Young Patients With Pathological Femoral Anteversion: A...

Pathological femoral anteversion (FAV) or femoral maltorsion is often overlooked as a cause of anterior knee pain (AKP). Therefore, it should be routinely evaluated during physical examination of the patient with AKP. FAV is a problem because it changes the direction of the quadriceps and thereby the force acting on the patellofemoral joint. The Murphy CT method comes closest to showing the anatomical reality when FAV is evaluated. The treatment of choice in a patient with AKP with symptomatic excessive FAV is the femoral derotational osteotomy. Before doing a derotational osteotomy, the hip joint should be evaluated to avoid hip pain. Currently, no scientific evidence supports the cutoff point at which derotational femoral osteotomy should be the treatment of choice in young patients with AKP with symptomatic pathological FAV. Furthermore, no evidence exists regarding the level at which the osteotomy must be done.
