Total hip replacement is widely used around the world for patients whose hip joints lost their functionality. Despite its wide applications and technological developments taking place in the recent years, it still does not produce near-perfect results. It has been observed that many patients with implants have their range of motion often restricted. Although there has been literature covering the daily life motion profiles in Western societies, , it has been observed that a through database of activities including sitting, worship, and lifestyles suitable for Middle Eastern societies is non-existent. Therefore, it is difficult to determine the lifespan of implants used especially in these societies and to determine their wear rates with accuracy. In this thesis, I have utilized the first comprehensive database of daily activities of Turkish population, which was formed using the state-of-the-art motion capture (MOCAP) technologies at Biomechanics and Motion Capture Laboratory of IZTECH. The range of motion and reaction force data were calculated using the inverse kinematics and kinetics methods previously. This previously calculated boundary conditions are fed into the finite element models of hip implants to simulate ten distinct daily life activities Asian style sitting, normal walking cycle, obstacle crossing, Stoop lifting, Squat lifting, Ruku’ and I’tıdal, Ruku to Sujud, Sujud, Ascending stairs, and Descending Stairs. The dynamic simulations of hip implants under these boundary conditions are performed in this thesis. In this thesis, a computational wear methodology is utilized to assess the wear performance of hip bearing surfaces under these boundary conditions. Each comprehensive computational wear simulations of each of these daily life activities over five million cycles is performed to provide computational evidence on the wear rates to assess the wear performance of the bearing couple. The wear prediction model could be utilized to provide guidance on the design parameters with the aim of prolonging the life span of hip implants.
