IC 307 - Patellar Instability: When is an MPFL Reconstruction Just Not Enough! A Case-Based Discussion (2/4)

Video Transcription

Video Summary

In this video, Dr. Betty discusses two cases of patellar instability. The first case is a patient with bilateral patellar instability who had a history of chronic instability since age 10. The right knee was more chronic and had recurrent dislocation in flexion, while the left knee had a routine instability. The patient underwent a derotational osteotomy to correct the rotational issues. The second case is a patient with unilateral instability who had a soft tissue surgery at age 15 that failed. The patient had significant valgus and baja, as well as a super trochlear spur. Dr. Betty performed a varus-producing osteotomy and proximalization of the extensor mechanism to correct the instability. The goal was to bring the trochlea into a neutral alignment and improve the patient's knee function. The video also discusses the importance of restoring quad strength in these patients.<br />No credits were mentioned in the transcript.
