摘要

前十字韧带在维持膝关节稳定性方面起着至关重要的作用,尤其是对于经常发生断裂的运动员而言。本研究提出了一种新方法,利用膝关节的个性化三维(3D)参数化有限元建模来模拟前交叉韧带重建(ACLR)后在前行(FW)和落地(DL)任务中的治疗情况。研究包括两个不同的组群:五名健康运动员和五名前交叉韧带重建患者。对这两个组别进行了生物力学运动分析,其中前交叉韧带损伤患者组别在手术后 6 个月和 9 个月进行了评估。我们精心制作了一个全面的膝关节三维参数模型。研究结果表明,随着时间的推移,前交叉韧带重建术后FW和DL任务中膝关节关键结构(如自体移植物、半月板和软骨)所受的压力明显减少,FW和DL的组织张力分别减少了约9.5%和37%。这种个性化模型不仅有助于研究 ACLR 术后膝关节组织的生物力学,还有助于估算患者恢复运动的时间表。通过考虑个体组织的几何形状并结合患者特定的运动学数据,该模型增强了我们对各种功能任务中 ACLR 后生物力学的理解,从而优化了康复策略。

Biomechanics of knee joint during forward-walking and drop-landing after anterior cruciate ligament reconstruction: finite element and gait analysis

The anterior cruciate ligament plays a crucial role in maintaining stability within the knee joint, particularly for athletes who frequently experience its rupture. This study presents a novel approach using personalized three-dimensional (3D) parametric finite element modeling of the knee joint to simulate the treatment following anterior cruciate ligament reconstruction (ACLR) in both forward walking (FW) and drop landing (DL) tasks. The study encompasses two distinct cohorts: five healthy athletes and five ACLR patients. Biomechanical motion analysis was conducted on both cohorts, with the ACLR patient group evaluated at 6 and 9 months post-surgery. A comprehensive 3D parametric model of the knee joint was meticulously crafted. The findings reveal a notable reduction in stress on crucial knee structures such as the autograft, meniscus, and cartilages over time for both FW and DL tasks following ACLR, with a reduction in tissue tension of approximately 9.5% and 37% for FW and DL, respectively. This personalized model not only facilitates the investigation of knee joint tissue biomechanics post-ACLR but also aids in estimating the return-to-sports timeline for patients. By accommodating individual tissue geometries and incorporating patient-specific kinetic data, this model enhances our comprehension of post-ACLR biomechanics across various functional tasks, thereby optimizing rehabilitation strategies.
