本研究旨在比较有和没有PFOA的个体在单腿蹲时的足部和踝关节活动度、足部姿势和动态膝关节外翻(以单腿蹲时的额平面投影角(FPPA)衡量)。作者发现，与对照组相比，PFOA患者的足部和踝部特征有所不同，但单腿深蹲时动态膝关节外翻没有差异。临床干预以解决更大的足灵活性可能与PFOA相关。

This study sought to compare foot and ankle mobility, foot posture and dynamic knee valgus, measured as the frontal plane projection angle (FPPA) during single-leg squatting, between individuals with and without PFOA. The authors found that foot and ankle characteristics were different in individuals with PFOA compared to control participants, however there was no difference in dynamic knee valgus during single leg squat. Clinical interventions to address greater foot mobility may be relevant for PFOA.
