Grooveplasty vs. Trochleoplasty for Trochlear Dysplasia in the Setting of Patellar Instability

Video Transcription

Video Summary

Mario Hevesi compared grooveplasty and trochleoplasty for treating trochlear dysplasia in patellar instability. Both procedures showed similar patient-reported outcomes, but grooveplasty had no recurrent instability compared to 33% in trochleoplasty. Grooveplasty reshapes the proximal groove, avoiding complications like hinge fractures. Ideal candidates differ: grooveplasty suits those with proximal, discrete bumps and long trochlea; trochleoplasty suits pan-trochlear bossing and short trochlea. Both are mainly used in revision surgeries. Overall, grooveplasty offers a viable alternative, with lower recurrent instability and comparable outcomes and revision rates in well-selected patients.
