Modeling and Finite Element Analysis of Knee Prosthesis with and without Implant

Abstract

Biomechanics is the study of the structure and function of biological systems by means of the methods of “mechanics” which is the branch of physics involving analysis of the actions of forces. Knee joint is the complex structure of the human body acquires the critical loads in various moving conditions. This paper discusses the loads acting on the joint during different motions such as steady, walking and lifting. A 3d modeling software PRO/E is used to prepare a CAD model of knee prosthesis and evaluate the results in the form of stresses by applying the calculated loads in the finite element analysis software ANSYS. The stresses are evaluated by considering several cases of loading. The aim is to study and evaluate the loads and stresses acting on knee joint and compared with the implant results.
