Outcomes of Medializing Tibial Tubercle Osteotomy With Medial Reefing and Vastus Medialis Obliquus Advancement Coupled With Lateral Retinacular Z-Lengthening for Recurrent Patellar Instability

ABSTRACT Purpose: Patella-femoral dislocations, although rare, can result in functionally limiting symptoms and limited return to prior activity levels. The purpose of this study is to report outcomes of a three-in-one patellar realignment surgery for treatment of recurrent patellar instability in a young, active duty military population. Methods: We conducted a retrospective chart review of all patients who underwent our senior author's three-in-one patellar realignment surgery for recurrent patellar instability in the setting of underlying anatomic malalignment. Our primary outcome measure was the rate of recurrent instability. Secondary outcome measures included rate of return to full unrestricted active duty military service and the functional outcome scores. Results: A total of 13 patients with an average follow-up of 16 months were included in this study. During the follow-up period, there were no reported instability events (either dislocation or subluxation). Three (23%) patients were separated se...
