Is There a Relation between The Lower Extremity Mechanics and Patellofemoral Pain Syndrome?

Objective: It has been theorized that changes in the lower extremity mechanics may lead to develop Patellofemoral Pain (PFP) in the young population. The present study aims to investigate the effects of lower extremity mechanics on Patellofemoral Pain Syndrome in private university students. 
Material and Methods: Kujala Pain Score (KPS) of 400 Yeditepe University students ages of 18-30 years was performed. Students having a less or equal point of 85 in KPS (n=30) and healthy groups randomly selected in students with KPS=100 (n=30) were measured in terms of Feiss Line, navicular drop, subtalar angle, tibial torsion, knee valgus angle, Q angle in standing and supine position and hamstring tightness. 
Results: The prevalence of PFP among students was found to be 10.5%(n = 42). In case and control groups were found 2nd Pes Planus (PP) as 16 (%53,3) and 3 (%10) respectively. A statistically significant difference was found between groups in navicular drop, subtalar angle, tibial rotation, Q angle in supine and hamstring tightness (p-value
