Abstract

Purpose: Cutting maneuvers are important actions in multidirectional sports but associated with noncontact anterior cruciate ligament (ACL) injuries. This study aimed to investigate the effect of different foot strike patterns and cutting angles on knee kinematics and kinetics.

Methods: Twenty healthy male team sports athletes performed cuts with maximum speed at three angles (45, 90 and 135°) with different foot strike patterns (rearfoot strike [RFS] and forefoot strike [FFS]). A three-dimensional motion capture system combined with a force plate was used to collect makers trajectory and ground reaction force (GRF). Vertical GRF, and knee joint angles and moments were compared among these cutting tasks.

Results: Regardless of foot strike patterns, increased knee flexion angle, knee valgus moment, and knee internal rotation moment were observed during cutting to sharper angles (p < 0.001). At 90 and 135°, the FFS condition remained in a varus position and showed lower knee flexion moment than the RFS condition ( p ≤ 0.004). However, no significant differences in knee kinematic and kinetic variables were found between foot strike patterns during cutting to 45°.

Conclusions: These findings suggest that sharper cutting angles potentially increase the risk of ACL injury. Compared with the RFS pattern, the FFS pattern induces a slight knee varus angle and a lower knee flexion moment at sharper angles, which might further reduce the load placed on the knee.

在侧切动作中，脚的击球模式和切入角度对膝关节运动学和动力学的影响。

目的：切入动作是多向运动中的重要动作，但与非接触性前交叉韧带（ACL）损伤有关。本研究旨在探究不同的脚踏模式和切入角度对膝关节运动学和动力学的影响：方法：20 名健康的男子团队运动运动员以最大速度在三个角度（45、90 和 135°）以不同的脚部击球模式（后脚掌击球[RFS]和前脚掌击球[FFS]）进行切削。三维运动捕捉系统与测力板相结合，用于收集运动者的运动轨迹和地面反作用力（GRF）。对这些切割任务的垂直反作用力、膝关节角度和力矩进行了比较：无论脚的打击模式如何，在切削到更大角度时，膝关节屈曲角、膝关节外翻力矩和膝关节内旋力矩都有所增加（p < 0.001）。在90°和135°时，FFS状态保持在屈曲位置，膝关节屈曲力矩低于RFS状态（P≤0.004）。然而，在切削到45°时，不同的脚着地模式在膝关节运动学和动力学变量方面没有发现明显差异：这些研究结果表明，更锋利的切入角度可能会增加前交叉韧带损伤的风险。与 RFS 模式相比，FFS 模式在更大的角度下会引起轻微的膝关节曲张角和更低的膝关节屈曲力矩，这可能会进一步减轻膝关节所承受的负荷。
