Figure 1. The common site of Osgood-Schlatter disease, the experimental setup, and flowchart of the inverse dynamic analysis. (A) Lateral view of the knee joint. The red area represents the common site of the Osgood-Schlatter disease. (B) Participants wearing the infrapatellar straps. (C) Position of the Vicon markers in front view. A total of 32 markers were placed; the locations were the shoulder, 7th cervical, clavicle, anterior and posterior superior iliac, thighs, knees, shanks, and feet.
