APEX Knee Navigating Pearls and Pitfalls-Trochleoplasty: When and How

Video Transcription

Video Summary

In the video, Dr. David Dedock discusses trochleoplasty, a technique used to address trochlear dysplasia and patella instability. He explains that trochlear dysplasia is a significant factor in recurrent patella dislocation and is more important than other risk factors such as malalignment. Dr. Dedock describes how to identify trochlear dysplasia using lateral X-rays and points out the importance of a "crossing sign" and a supratrochlear spur in making the diagnosis. He emphasizes the use of three-dimensional imaging like MRI or CT for a better understanding of the condition. He goes on to discuss patella tracking issues associated with trochlear dysplasia and explains the role of patella alta in decision-making for trochleoplasty. He also discusses different types of trochlear dysplasia and indicates which types are likely to require surgical intervention. Dr. Dedock presents the two methods of trochleoplasty: the thick shell technique and the thin flap technique. He provides a step-by-step explanation and demonstration of the thick shell technique, including how to remove the supratrochlear spur and reshape the trochlear groove. He concludes by discussing postoperative rehabilitation and sharing the positive outcomes of trochleoplasty procedures. No credits were granted in the video.
