Surgical correction of miserable malalignment syndrome

Abstract

Anterior knee pain is one of the more frustrating problems that orthopaedic surgeons treat. This study investigates the results of surgical correction of miserable malalignment syndrome associated with significant patellofemoral pain. The authors identified and retrospectively reviewed 14 consecutive patients with 27 limbs associated with excessive femoral anteversion, excessive tibial outward rotation, and patellofemoral pain. All of the patients were initially reviewed by the senior author and subsequently treated by ipsilateral outward femoral osteotomy and inward tibial osteotomy. All of the patients had failed nonoperative treatment. No persistent complications were seen. Subjectively and clinically, all of the patients were reviewed at an average of 5.2 (range 2.0-12) years after surgery. All of the patients reported full satisfaction with their surgery and outcomes. Most of the current literature discusses alignment in association with patellofemoral pain in the form of the extensor mechanism alignment. When evaluating patients with patellofemoral pain, it is imperative to assess the rotational profiles of the femur and tibia. The authors recommend that rotational osteotomies be performed in patients with patellofemoral pain and associated excessive femoral and tibial torsion, otherwise known as miserable malalignment syndrome.
