Purpose: To determine the dynamic Q angle during walking in healthy young women, examine its correlation with the static Q angle, and identify factors associated with the dynamic Q angle. Methods: One hundred healthy young women, aged between 18 and 25, were enrolled. The dynamic Q angle was evaluated during the mid-stance phase of walking. The Q angles were then determined using two-dimensional video analysis software (Kinovea 0.8.15, GPLv2 license, 2019). Factors such as pelvic width, thigh length, femoral anteversion angle, lower extremity muscle strength, Beighton score, foot posture index-6, and gait speed were measured to identify their association with the dynamic Q angle. Results: The dynamic Q angles were 17.87 degrees (±5.35) and 20.08 degrees (±5.83), right and left knees, respectively, for 100 young healthy women (21.31±1.48 years). The dynamic Q angle is smaller than the static Q angle. There was a moderate correlation between the dynamic and the static Q angles (r=0.525, p<0.01). Side-to-side differences in Q angles between knees were higher in the dynamic Q angle. The dynamic Q angle had a significant relationship with weight, femoral anteversion and knee extension strength (rho=0.198, p=0.048; r=0.272, p<0.01; r=-0.209, p<0.05, respectively). Conclusion: The dynamic Q angle was smaller than the static Q angle and showed a moderate correlation with static measurements in young healthy women. Greater side-to-side differences and significant associations with body weight, femoral anteversion, and knee extensor strength suggest that dynamic assessment may better reflect functional alignment and complement static evaluation. Future studies should include both sexes and examine dynamic Q angle assessment in clinical populations, such as individuals with patellofemoral pain.
