目的：在非接触性前交叉韧带损伤的“高风险”运动中，描述女性下肢生物力学的数据缺乏。本研究比较了不同性别的膝关节运动学与回避动作的关系，以深入了解为什么女性的这种损伤发生率明显高于男性。方法：30名参与者（16名男性，14名女性）在回避时记录双侧膝关节运动学数据。定制软件包（JTMOTION）量化了20次以上临床膝关节旋转（屈/伸、内收/外展和外/内旋）中每一次站立时的最大、最小和运动范围（腿X条件X试验(5)）。结果：性别差异具有有限的临床意义，所有最大值都在膝关节运动的安全范围内。然而，与男性相比，女性在切割过程中轴向旋转模式的试验间变异性增加。这种可变性被认为不受性别的影响，经验水平在统计学上（P < 0.01）是回避时膝关节运动可变性的主要决定因素。因此;当一个人进行这些动作时，暴露于侧台阶切割的程度可能对随后的ACL损伤风险有很大的影响。结论：与男性相比，切割过程中膝关节运动的性别差异并不会增加女性非接触性前交叉韧带损伤的风险。因此，发病率增加的原因尚不清楚。性别与其他与ACL损伤相关的参数（如关节几何形状、韧带形态和身体状况）之间的潜在关系需要进一步研究。
Purpose: There is a paucity of data describing female lower limb biomechanics during "high risk" movements linked to noncontact ACL injury. This study compared, across gender, knee kinematics associated with sidestepping maneuvers to provide insight into why women display a significantly higher incidence of this injury than do men. Methods: Thirty participants (16 men, 14 women) had bilateral knee joint kinematic data recorded while sidestepping. A custom software package (JTMOTION) quantified maximum, minimum, and range of motion during stance for each of the three clinical knee joint rotations (flexion/extension, adduction/abduction and external/internal rotation) over 20 (leg X condition X trial (5)) trials. Results: Gender differences possessed limited clinical significance with all maximum values well within safe ranges of knee motion. Women did, however, display increased intertrial variability for axial rotation patterns during cutting compared with men. This variability was thought to be unaffected by gender, with experience level found statistically (P < 0.01) to be the major determinant of knee kinematic variability during sidestepping. Hence; the level of exposure to sidestep cutting may have a large impact on the subsequent risk of ACL injury when when one performs these maneuvers. Conclusions: Gender differences in knee motions during cutting did not contribute to the increased risk of noncontact ACL injury in women compared with men. The reasons for this increased incidence, therefore, remain unclear. The potential relationship between gender and other parameters linked to ACL injury such as joint geometry, ligament morphology, and physical conditioning requires further investigation.
