Assessment of Patellar Instability_ Consider These Factors-Faculty Lecture_ Patrick Kane, MD

Video Transcription

Video Summary

Dr. Patrick Cain discusses patella instability, highlighting its prevalence and variable re-dislocation rates. Evaluation emphasizes anatomical factors like limb alignment (genu valgum), patellar height (patella alta), trochlear morphology, and less emphasis on TTTG distance. Imaging, including true lateral radiographs and MRI, is crucial. Soft tissue structures such as MPFL, MPML, and MPTL contribute to stability, with MPFL reconstruction central to treatment. Dynamic stabilizers and addressing functional valgus via physical therapy are important. Risk stratification considers modifiable and non-modifiable factors, advocating individualized treatment plans addressing specific anatomical and functional issues for optimal outcomes.
