Abstract

Patellofemoral pain (PFP) is a common injury in runners, especially females, but it is unclear if the kinematic risk factors between the sexes are the same. This study aimed to identify the kinematics of healthy and injured recreational runners with PFP in both sexes. High-speed videos of treadmill running gait in 56 subjects (14 in each injured and non-injured male and female group) were analysed using the Kinovea software. Three kinematic variables associated with PFP were extracted at midstance: knee midstance position, knee flexion angle, and hip adduction angle. Compared with healthy controls, injured females ran with knees more medially positioned (Left p = 0.008, Right p < 0.001), while injured males ran with less knee flexion (Left p = 0.006, Right p = 0.007). These findings suggest that kinematic risk factors associated with PFP are sex-specific.
