Trochleoplasty: When is it Optimal to Add for Patellar Stabilization?

Video Transcription

Video Summary

Dr. Liza Arendt gave a presentation on trochleoplasty, focusing on its history, types, indications for surgery, and surgical techniques. Trochleoplasty is a surgical procedure performed to address trochlea dysplasia, a condition where the groove in the femur that guides the kneecap is shallow or malformed. Dr. Arendt emphasized the importance of patient selection and imaging criteria, such as the "J sign" on physical examination and the presence of a supratrochlear spur. She discussed different classification systems for trochlea dysplasia, including the length of the trochlea, the presence of a supratrochlear spur, and the hypoplasia of the medial trochlear facet. Dr. Arendt also mentioned the use of true lateral x-rays for evaluation and the need to consider the depth and length of the trochlea. The surgical technique involves creating a new groove in the femur and removing the supratrochlear spur. She concluded by emphasizing the importance of the true lateral x-ray in diagnosing and planning for trochleoplasty. Dr. Arendt gave credit to various individuals and sources, including David DeJure and Arthrex, for some of the video content and information provided.
