The purpose of this study was to quantify in vivo anterior cruciate ligament (ACL) strain by computer simulation, which includes a marker-based biomechanical model and a skeletal geometry model. Kinematic data collected by a motion capture system was used as the input and ACL strain during the movement time period was the output. Case studies were conducted to simulate ACL strain during jump landing, running and sidestep cutting activities. The simulation results were analysed and compared with previous findings in literature. The results show that the simulation is a useful tool in understanding ACL injury mechanisms related to sports activities.
本研究的目的是通过计算机模拟量化体内前交叉韧带（ACL）的应变，包括基于标记的生物力学模型和骨骼几何模型。运动捕捉系统采集的运动学数据作为输入，运动过程中的 ACL 应变作为输出。通过案例研究模拟了跳跃着地、跑步和侧身切割活动过程中的 ACL 应变。对模拟结果进行了分析，并与文献中的先前发现进行了比较。结果表明，该模拟是理解与运动相关的 ACL 损伤机制的有用工具。
