Mean (SD), degree; An asterisk (*) indicates significant sex-based differences (P < 0.05). No significant difference
among 3D, Human, and OpenPose. No interaction effect between these factors. 3D: three-dimensional motion
analysis, Human: human visual detection-based motion analysis, OpenPose: OpenPose-based motion analysis,
COG: center of gravity, Negative values represent the knee valgus angle.
