Complication Rates Following Tibial Tubercle Osteotomy With and Without Distalization in Young Patients With Patellar Instability: A Multicenter Study.

Background: Tibial tubercle osteotomy (TTO) is a surgical procedure for the management of patellofemoral instability (PFI). Tubercle distalization requires a complete osteotomy detachment and has been shown to have an increased rate of certain complications in predominantly adult cohorts. With this study we identify and compare the complication rate of 2 TTO techniques-anteromedializing alone (AM) and anteromedializing with concomitant distalization (AMD) among young patients.
