Bio-mechanical Analysis of Knee Stresses Based on Finite Elements Approach

Abstract

Software tools based on finite element analysis are widely used for structural mechanical analysis and even in other areas such as medicine. This research analyzes the efforts that occur in the two most important bones that are part of the knee joint from computerized axial tomography (CT) and proposes a methodology based on finite element meshes to obtain these efforts. From the simulation of the geometry of a real knee, stress-strain curves have been developed. The results obtained from the simulation showed that the stress pattern is at a value of 10.97 Mpa in the area between the intercondylar eminence and the intercondylar notch and a unit strain of 1.05 × 10 − 2 mm for the femur and 8, 5 × 10 − 4 mm in warm.
