Course Lecture Pearls: Advanced Knee-Patellofemoral-Trochleoplasty; When to Consider in 2019-Faculty Lecture

Trochleoplasty; When to Consider in 2019-Faculty Lecture_ Elizabeth Arendt, MD

Video Transcription

Video Summary

Dr. Eliza Rent discusses trochleoplasty techniques—thick flap osteotomy and thin flap (Berriter technique)—and their indications. Patient selection requires functional disability, poor knee confidence, a prominent J sign, and imaging confirming high-grade trochlear dysplasia, characterized by specific radiographic signs and measurements. The procedure involves arthrotomy, groove marking, bone undermining, flap mobilization, groove deepening, and fixation, preserving cartilage and bone. Outcomes show improved sulcus angles and reduced supratrochlear spur. Despite technical challenges, trochleoplasty is crucial for patellofemoral instability treatment, enhancing patients' quality of life. The talk emphasizes detailed anatomy understanding, imaging interpretation, and surgical precision.
