Outcomes of Medial Patellofemoral Ligament Reconstruction With Concomitant Tibial Tubercle Osteotomy for Failed Surgery for Patellar Instability Versus Primary Medial Patellofemoral Ligament Reconstruction With Concomitant Tibial Tubercle Osteotomy

Key Points

Patients report significant clinical and statistical improvements in patient-reported outcome measures (PROMs).
Both primary and revision surgeries demonstrate low rates of recurrent instability post-operatively.
Analysis of surgical outcomes highlights the effectiveness of MPFL-reconstruction combined with tibial tubercle osteotomy.
Further research is warranted to validate long-term outcomes across diverse patient populations.

Abstract

This study demonstrates that MPFL-Reconstruction + TTO is a reliable and reproducible procedure whether performed in the primary or revision setting. Patients who had primary and revision surgery reported clinical and statistical improvements in nearly all PROMs over time, with low recurrent instability and high RTS rates in both groups.
