摘要:
目的:通过三维有限元技术,解析理筋提髌手法通过改善髌骨的运动轨迹治疗髌股关节炎的力学机制。方法:以一名早期髌股关节炎患者的右膝为初始资料,根据CT扫描图像,应用有限元相关软件完成膝关节有限元模型构建。加载条件为对股四头肌腱施以200 N拉力,根据理筋提髌手法治疗髌股关节炎临床研究获得的影像学数据进行相关模型数值的干预,分别于膝关节屈曲90°、60°和30°位,对比干预前后髌股关节面应力分布和应力大小变化情况。结果:膝关节屈曲90°、60°和30°时,髌骨软骨关节面的应力峰值干预组较未干预组分别下降了0.47、0.99和1.81 MPa; 股骨滑车软骨关节面的应力峰值干预组较未干预组分别下降了0.72、0.73和1.64 MPa; 髌股关节面应力分布的面积有所增大,应力集中的异常情况有所改善。结论:理筋提髌手法可通过改善髌股关节面异常的应力大小和应力分布治疗早期髌股关节炎。
Abstract:
To analyze the mechanical mechanism of treating patellofemoral osteoarthritis by improving the patella movement track through the three-dimensional finite element technology.Methods:A finite element model of patellofemoral joint was constructed based on CT images of the right knee of a patient with early patellofemoral osteoarthritis.The loading condition was 200 N tension on the quadriceps tendon,and the relevant model value intervention was carried out according to the image data obtained from the clinical study of treating patellofemoral osteoarthritis with tendon manipulation.The stress distribution and changes of the patellofemoral joint surface were studied before and after intervention at 90°,60° and 30° flexion of the knee respectively.Results:The stress peak value of the articular surface of patellar cartilage in intervention group decreased 0.47,0.99 and 1.81 MPa respectively compared with non-intervention when the knee flexion was 90°,60° and 30 °.The peak stress of the articular surface of the femoral trochlea in intervention group decreased by 0.72,0.73 and 1.64 MPa compared with non-intervention group respectively,and the area of the stress distribution of the patellofemoral surface increased and the abnormality of the stress concentration improved.Conclusion:The manipulation of regulating tendon and moving kneecap can improve the stress magnitude and distribution of abnormal patellofemoral joint surface on treatment of early patellofemoral osteoarthritis.
