2023 Annual Meeting Knee Access Pass-My Tips for Clinical Evaluation and Radiographic Assessment With Patella Instability

My Tips for Clinical Evaluation and Radiographic Assessment With Patella Instability

Video Transcription

Video Summary

Dr. Adam Yanke discusses key factors in evaluating patellar instability, emphasizing four major measurements: patella alta, dysplasia, J-sign, and tibial tubercle–trochlear groove distance (TTTG). These factors predict risks of redislocation and poor outcomes after MPFL reconstruction. He highlights the importance of assessing knee flexion stability under anesthesia and rotational profiles from hip to ankle. Accurate imaging and patient-specific analysis guide treatment, which may include osteotomies, trochleoplasty, and MPFL reconstruction. Dr. Yanke advocates for a systematic approach to evaluation using evidence-backed metrics to improve clinical decision-making and outcomes in patellar instability management.
