MODELLING AND ANALYSIS OF KNEE FLEXION MOVEMENT

Abstract

The model of three-dimensional model of knee joint is based on MRI data which is built in Mimics Software, which included the three parts of knee bone, Femur, tibia and Patella. And then analyzed. Dynamic finite element (FE) model (ANSYS) of knee will be developed to simulate both the kinematics and the internal stresses during knee flexion movement. My study is only focused on macroscopic level. The 3 dimensional model will be used to simulate knee gait system of a healthy volunteer. The flexion motion and dynamic contact characteristics of knee will be analyzed, and will be verified by comparing with the data from experiment. The results will show that the established dynamic Finite Element model of the knee are capable of predicting contact stresses during flexion.
