Abstract:

Introduction. 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. Material and Method. A series of modern devices and equipment that were used for the three-dimensional reconstruction of the components of the analyzed systems. Results. 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. Discussion. The results obtained consisting of maps of displacements, deformations and stresses were stored, analyzed and compared. Conclusions. Finally, important conclusions were highlighted.


Keywords:
Degree of varus / valgus, finite element method, CAD methods, knee prosthesis.
