Relationship of Baseline Physical Activity and Morphologic Factors in Patients With Lateral Patellar Instability

The authors aimed to investigate the relationship between baseline physical activity levels and morphologic factors in patients with lateral patellar instability. The study found that competitive athletes had greater trochlear depth compared to recreational and nonsports groups, yet both competitive and nonsports participants frequently required bilateral surgeries, suggesting that severe trochlear dysplasia may play a significant role beyond just activity levels in surgical decision-making. These results underscore the need to consider both activity and trochlear morphology when evaluating young patients for surgical interventions.
