Generalized Ligamentous Laxity Is Associated With Surgical Failure Following Patellofemoral Stabilization

Description

The presentation by Laurie Hiemstra focuses on a research study regarding surgical failures after patellofemoral stabilization, which aimed to identify factors related to unsuccessful outcomes. The objectives included reporting the failure rate within a large cohort of patients (590 knees) experiencing recurrent instability. The study highlights a failure rate of 4.8%, meaning that 28 out of 590 procedures resulted in patellar redislocation. Key findings indicate that generalized ligamentous laxity, particularly measured through the Beighton score, was significantly associated with these failures, as was trochlear dysplasia. The investigation also involved analyzing revision procedures undertaken for failed patients, revealing a variety of surgical adjustments made to enhance stability. Hiemstra concludes that while patellofemoral stabilization generally shows positive results, considerations of pathoanatomic risk factors are essential for improving surgical outcomes.
