2021 Annual Meeting Knee Access Pass-Surgical Technique Spotlight: Trocheoplasty (video)

Surgical Technique Spotlight: Trocheoplasty (video)

Video Transcription

Video Summary

The speaker discusses trochlear dysplasia as a major risk factor for recurrent patella instability, emphasizing the importance of recognizing and quantifying it via lateral X-rays and MRI. Key indicators include a convex supratrochlear spur greater than 7mm and presence of patella alta, which together can severely affect patella tracking, often evidenced by a jumping J sign. Treatment decisions hinge on these factors; flat trochleas typically respond well to MPFL reconstruction alone, whereas prominent convex spurs may require a deepening trochleoplasty. The speaker details a surgical thick shell trochleoplasty technique to correct the deformity, stressing immediate postoperative motion to prevent scarring and noting good outcomes.
