Patellofemoral Instability From Simple to Complex: How to Get it Right (4/6)

Video Transcription

Video Summary

The video discusses a case involving a 24-year-old woman with a left knee dislocation and a history of both knees dislocating for the past 10 years. She experiences high apprehension and desires to play basketball. The clinical examination reveals valgus, hyperextension, and painful knees with apprehension. Patellar-specific apprehension is tested, and abnormal patellar tracking is observed. Imaging shows trochlear dysplasia type D, flat trochlea, patella alta, and a supratrochlear spur. Trochleoplasty is performed to correct the trochlear abnormality, along with a tibial tuberosity osteotomy, and an MPFL reconstruction. The post-operative results show improvement in anatomical alignment and stability. The importance of correcting trochlear dysplasia and addressing vector realignment is emphasized.
