摘要:


文题释义:
有限元:有限元方法是利用数学近似的方法模拟真实的物理系统,其原理是将建立的几何模型分成许多离散的小区域,这些小区域是具有线性代数方程系统并且在各顶点处相互结合,表示为矩阵方程,假设对每一个单元有一个近似解,然后推导出可以满足这个结构平衡的条件,从而得到问题的解。
髌腱炎:又称为“跳跃者膝”,常发生于篮球、排球、跳高、跳远等需要快速加速、频繁改变方向或重复运动的项目。该病通常表现为组织病变,组织超负荷且未完全恢复而导致愈合失败的肌腱退化。

背景:髌腱炎可表现为组织超负荷且未完全恢复而导致愈合失败的肌腱退化。髌腱炎是跳高运动的易发病,其发病机制尚未明确。
目的:通过具有精确人体解剖结构的有限元模型探究跳高起跳技术动作中髌腱的应力应变关系,为预防髌腱炎与康复提供思路。
方法:基于1名受试者(22岁,身高183 cm,体质量70 kg)包括膝、踝的下肢CT与MRI影像数据,采用医学影像软件、逆向工程软件和建模软件重建下肢三维有限元模型。通过步态测试系统采集8名受试者起跳腿的足底压力,并使用运动捕捉系统采集跳高起跳技术动作,将捕捉数据导入人体运动生物力学软件进行分析,获得运动学和动力学数据作为下肢三维有限元模型的边界条件,进行有限元仿真分析。
结果与结论:在受试者起跳时髌腱承受的力达到自身体质量的3.29倍。在起跳阶段,髌腱的范式等效应力、应变、剪切应力峰值分别为127.76 MPa、0.81、37.69 MPa,处于应力-应变曲线的非线性区域,峰值分布于髌腱近端后部。结果提示,跳高运动起跳时髌腱承受自身3.29倍体质量的载荷引起的高髌腱力、应变和剪切应力与诱发髌腱炎相关。

Abstract: BACKGROUND: Patellar tendonitis can present as tendon degeneration that fails to heal due to tissue overload and incomplete recovery. Patellar tendonitis is a predisposition to high jumping and its pathogenesis has not been clearly defined.
OBJECTIVE: To explore the stress-strain relationship of patellar tendon in the take-off technique of high jump through the finite element model with accurate human anatomical structure, so as to provide ideas for the prevention and rehabilitation of patellar tendinitis.
METHODS: Based on the CT and MRI imaging data of the lower extremity (including the knee and ankle) of one subject (22 years old, 183 cm height, 70 kg body mass), a three-dimensional finite element model of the lower extremity was reconstructed using medical imaging software, reverse engineering software and modeling software. The plantar pressure of the take-off leg was collected in eight subjects by gait testing system, and the technical action of high jump take-off was collected by motion capture system. The captured data were imported into human sports biomechanics software for analysis, and kinematic and kinetic data were obtained as the boundary conditions of finite element model for finite element simulation analysis.
RESULTS AND CONCLUSION: The force borne by the patellar tendon reached 3.29 times of its own body mass when the subjects took off. In the take-off stage, the peak values of normal equivalent stress, strain and shear stress of the patellar tendon were 127.76 MPa, 0.81 and 37.69 MPa, respectively, which were in the nonlinear region of the stress-strain curve, and the peak values were distributed in the proximal and posterior parts of patellar tendon. To conclude, the high patellar tendon force, strain and shear stress caused by the load of 3.29 times its own body mass during take-off are related to the induction of patellar tendinitis.
