Patellofemoral Instability From Simple to Complex: How to Get it Right (3/6)

Video Transcription

Video Summary

In this video, the presenter discusses the case of a 13-year-old female athlete who has experienced multiple patella dislocations. The patient has a significant ligament laxity, which is causing the patella to dislocate when her knee is fully extended. The presenter shows videos and images of the patient's knee during physical examination, highlighting the jumping J sign, which is a characteristic of an obligatory dislocator. The presenter also discusses the patient's skeletal status, including measurement of the tibial tubercle-trochlear groove (TTTG) distance and the lateralized tubercle. Trochlear dysplasia is also identified as a factor contributing to the patient's instability. The presenter discusses the available treatment options, including bracing, physical therapy, and surgical interventions. The presenter also highlights the importance of addressing the instability early to prevent further damage to the knee joint. In the case presented, the patient underwent an MPFL (medial patellofemoral ligament) reconstruction, and later required a TTO (tibial tubercle osteotomy) due to recurrent instability. The presenter emphasizes the need to consider various factors, such as patella tracking, alignment, and skeletal maturity, when determining the appropriate surgical approach.
