According to recently published results, trochleoplasty yielded good clinical outcomes, a low redislocation rate and an “acceptable” complication profile at short- and long-term follow-up.
“Trochleoplasty clearly needs to be in the toolbox of the experienced patellofemoral surgeon,” Laurie A. Hiemstra, MD, PhD, FRCSC, told Healio.com/Orthopedics. “A greater understanding of the interaction of the varying risky anatomic features associated with patellofemoral instability, as well as a more comprehensive and reliable classification system for trochlear dysplasia, will help us to determine which patients are most likely to benefit from this procedure. “
Hiemstra and colleagues used OVID Medline, OVID EMBASE and the Cochrane Library to identify 29 studies which included 998 patients who underwent trochleoplasty for lateral patellofemoral instability. Investigators abstracted information from 21 studies for the secondary analysis of clinical outcomes and found a degree of trochlear dysplasia and significant heterogeneity in patient selection and patient-reported outcomes.
Results showed most of the studies were performed in Europe. The open thin flap technique was used in most studies.
Investigators noted significant improvements in clinical outcomes for all trochleoplasty techniques at an average of 50 months postoperatively. Most patients reported they were satisfied with their procedure. There were low rates of redislocation and complications. – by Monica Jaramillo
