Abstract

The Femoroacetabular Impingement (FAI) causes pain and reduction of range of motion. FAI also causes abnormal contact stress and potential joint damage
around hip. We investigated the kinematics of a hip joint when a FAI occurs. In this study we put forward the following hypotheses: Does changing the kinematics of motion affect the contact surface/forces? Does changing the
kinematics of motion eliminate the need of cutting the bump?
The study uses a finite element (FE) model of the hip joint to analyse the biomechanics of the hip at the impingement zone. The model was initially analysed using the original kinematics of the joint. The kinematics was
then changed with a stepwise increase and decrease of the gap between the femur and the acetabulum to evaluate its effect on the FAI contact zone. The study demonstrated that the joint motions such as flexion, adduction and internal rotation changed with variation of the gap between the femur and the acetabulum.
