Abnormal motion of the foot has been suggested to be a potential contributor to the medial collapse of the knee seen in individuals with patellofemoral pain syndrome during a one-leg squat. Rearfoot frontal plane range of motion and peak angle were investigated during a one-leg squat in patients with patellofemoral pain syndrome compared with controls. A significant increase in the peak eversion angle was found for the patellofemoral pain syndrome group compared with controls (P = .02). Increased rearfoot eversion may contribute to the knee medial collapse observed in these patients because it may lead to tibial abduction relative to the femur. Nevertheless, further research is required to investigate the causal relationship because it remains unclear whether rearfoot eversion instigates the medial collapse of the knee.
足部异常运动被认为是导致髌股疼痛综合征患者在单腿深蹲时出现膝关节内侧塌陷的一个潜在因素。与对照组相比，研究了髌股疼痛综合征患者在单腿深蹲过程中的后足额状面运动范围和峰值角度。与对照组相比，髌股疼痛综合征组的峰值外翻角度显著增加（P = 0.02）。后足外翻增加可能导致这些患者出现膝关节内侧塌陷，因为它可能导致胫骨相对于股骨外展。然而，由于后足外翻是否引发膝关节内侧塌陷仍不清楚，因此需要进一步研究来探讨因果关系。
