The human knee is one of the most complex human joints, by the number of components, by the stresses to which it is subjected, by the complicated spatial geometry of the components and by the existence of multiple contacts between different components.
A series of modern devices and equipment that were used for the three-dimensional reconstruction of the components of the analyzed systems.
Also, the elements of a knee prosthesis were modeled in a parameterized virtual environment and six orthopedic systems were compared. These systems have been studied using the finite element method using loads specific to normal human gait.
The results obtained consisting of maps of displacements, deformations and stresses were stored, analyzed and compared.
Finally, important conclusions were highlighted.
从组成部件数量、所承受的应力、部件复杂的空间几何形状以及不同部件间存在多重接触等方面来看,人体膝关节是最复杂的人体关节之一。
使用了一系列现代设备和仪器对所分析系统的部件进行三维重建。
此外,在参数化虚拟环境中对膝关节假体的元件进行了建模,并比较了六个骨科系统。已使用有限元方法,采用正常人类步态的特定负荷对这些系统进行了研究。
所获得的由位移、变形和应力图组成的结果被存储、分析和比较。
最后,突出了重要结论。
