Accuracy of the Schöttle Technique for Femoral Medial Patellofemoral Ligament Footprint Localization in Trochlear Dysplasia: A Fluoroscopic Case-Control Study on 3-Dimensional-Printed Femurs.

While a non-significant trend toward poorer accuracy in female patients with severe trochlear dysplasia was noted, the results did not reach statistical significance, and most of the variability remained unexplained by the presence or severity of trochlear dysplasia. 10) Additionally, systematic anatomical reviews emphasize the broad interindividual variability of MPFL origin and insertion sites—even among cadavers without patellar instability.
