Meta AnalysisIsolated trochleoplasty for recurrent patellar dislocation has lower outcome and higher residual instability compared with combined MPFL and trochleoplasty: a systematic review.
To identify the efficacy of isolated trochleoplasty (TP) as an independent treatment for severe trochlear dysplasia compared with TP combined with medial patellofemoral ligament (MPFL) reconstruction. ⋯ Trochleoplasty is a useful and reliable surgical technique to improve patellofemoral instability in patients with a dysplastic trochlea. However, it as isolated treatment for patients has lower outcome and higher residual instability compared with combined MPFL and trochleoplasty.
