High prevalence of generalized ligamentous laxity in patellar dislocation with posterior weight-bearing lateral femoral condyle osteochondral fractures: an observational study and treatment outcomes

In the selective cohort of "patellar dislocation with concomitant osteochondral lesions in the posterior weight-bearing zone of the lateral femoral condyle" included in this study, multiple ligament laxity signs exhibited a high incidence rate. Although the current study design precludes exploration of the underlying mechanisms, the coexistence of ligament laxity with baseline anatomical features supports a plausible hypothesis: patients with multiple ligament laxity syndrome may exhibit altered patellofemoral kinematics and energy transfer pathways under dynamic loading. And early surgical intervention involving reduction and fixation with resorbable cartilage pins combined with medial patellofemoral ligament (MPFL) reconstruction may represent a reliable and feasible treatment strategy.
