背景：在步态过程中正常的三维膝关节运动学仍然没有得到很好的理解，特别是关于女性和男性之间的差异。研究问题：本研究的目的是用一种有效的工具来描述健康女性和男性步态中的三维膝关节运动学。方法：对90例健康受试者（女性49例，男性41例）进行膝关节运动学分析。对女性和男性、右膝和左膝的三维膝关节旋转进行比较。每位受试者都接受了全身负重x光检查。评估外展-内收角度与x射线下肢对齐测量之间的相关性。结果：在额平面，女性比男性多发生2.0-5.0度外展（0.000）
Background: Normal 3D knee kinematics during gait is still not well understood, especially regarding differences between women and men.Research question: The objective of the present study was to characterize 3D knee kinematics during gait in healthy women and men with a validated tool.Methods: Knee kinematics was analysed with the KneeKG (TM) system in 90 healthy subjects (49 females and 41 males). 3D knee rotations were compared between women and men, and between right and left knees. Each subject underwent full-length weight-bearing x-rays. Correlations between abduction-adduction angles and lower-limb alignment measures on x-rays were assessed.Results: In the frontal plane, 2.0-5.0 degrees more abduction occurred in women compared to men (0.000
