摘要:
目的:探讨基于计算机运动仿真技术对膝关节假体参数的优化。方法:纳入500例健康志愿者于2019年5月至2021年5月进行体检,不同膝关节屈曲健康志愿者体内内外侧髁前后移位距离与模型进行比较; 不同步态周期时健康体检者下蹲和坐立运动时,胫股关节总体接触力测量值与模型预测值比较。结果:健康体检者在0°,30°,60°,90°膝关节屈曲时,体内内外侧髁前后移位距离与模型进行比较,差异无统计学意义(P>0.05)。在下蹲、坐立两种运动方式下对模型进行验证后表现出较好的适应性,同时维持着对膝关节假体接触力的高度预测,为后续个体化骨肌假体的广泛应用提供理论依据。结论:以计算机运动仿真计数为基础,建立膝关节置换术后运动力学仿真模型,为膝关节假体数据优化提供依据。
Abstract:
Objective:To discover the optimization of knee prosthesis parameters based on computer motion simulation technology.Methods:A total of 500 healthy volunteers included in this study were examined in hospital from May 2019 to May 2021. The anteroposterior displacement distance of the inner and outer ankles of healthy volunteers with different knee flexion was compared with the model. The total contact force of the tibiofemoral joint was measured and compared with the predicted value of the model during squatting and sitting exercises of healthy people in different gait cycles.Results:There was no significant difference between the anteroposterior displacement distance of medial and lateral malleolus of healthy people and that of the model during knee flexion at 0°, 30°, 60° and 90°(P>0.05). The model showed good adaptability after being verified in squatting and sitting, while maintaining the high prediction of the contact force of knee prosthesis, providing a theoretical basis for the subsequent extensive application of individualized skeletal muscle model.Conclusion:The biomechanical simulation model after knee replacement is established to provide a basis for the optimization of knee prosthesis data based on the count of computer motion simulation.
