2021 AOSSM-AANA Combined Annual Meeting Recordings-Surgical Technique Spotlight: Trocheoplasty (video)

Surgical Technique Spotlight: Trocheoplasty (video)

Video Transcription

Video Summary

In the video, the speaker discusses trochlear dysplasia and its association with recurrent patellar instability. They highlight the importance of recognizing dysplasia through lateral x-rays and further evaluating with three-dimensional imaging. The presence of a supratrochlear spur and convexity in the trochlea can have a profound impact on patellar tracking, leading to instability. The speaker emphasizes the importance of measuring patellar height and considering a trochleoplasty for patients with convex spurs greater than seven millimeters, especially in combination with patella alta and a jumping J sign. The video demonstrates the thick shell technique for trochleoplasty, involving reshaping and elevating the trochlea to improve patellar tracking. The presenter suggests that trochleoplasty can benefit patients with convex trochleas, but not necessarily for those with flat spurs or pain.
