| Abstract: | Total knee arthroplasty is one of the most commonly performed procedures in the field of adult reconstructive
surgery and the number of procedures continues to increase. [1]
This paper proposes a model of total knee prosthesis. The prosthesis geometry is established based on 3D reconstruction of
CT images. Using Mimics and Magics software, 3D solid models of the tibia and femur are obtained. The designed prosthesis
has two main metallic components (femoral and tibial component) and an intermediate plastic component. Thus, the space
between the two metal inserts is filled with high density polyethylene which is resistant to wear but decreases the amount of
friction between the two metal plates.
The mechanical behavior of the proposed prosthesis is studied based on numerical analysis, using ANSYS software. The
stress and strain distributions are determined. |
