Objective: The lines connecting the anterior superior iliac spine to the center of the patella and the center of the patella to the tibial tuberosity make the quadriceps angle (Q angle), and this can be used as data for patellar alignment. We undertook this study to provide detailed information about the change of Q angle values with age and activity.
