AANA Knee Arthroscopy - September 2024-Critical Clinical Assessment of Patellofemoral Patient

Critical Clinical Assessment of Patellofemoral Patient

Video Transcription

Video Summary

This talk covers the clinical assessment of patellofemoral instability, emphasizing the role of ligamentous restraints, muscular forces, and bony anatomy. Key risk factors include trochlear dysplasia, patella alta, and malalignment. Differentiating dislocation, subluxation, maltracking, and laxity is crucial. Clinical exams assess patellar stability, mobility, alignment (Q angle), muscle function, and generalized laxity (Beighton score). Specific tests include patellar glide, apprehension, tilt, and the J sign. Imaging via weight-bearing X-rays, MRI, CT, and advanced 4D CT helps evaluate anatomy, injuries, and patellar tracking for tailored treatment.
