Abstract
This research aims to analyze the contact pressure on acetabular cup surface with dimple addition and without dimple addition. The main contribution in this research is to explore the influence of dimple addition to contact pressure that affects implant lifetime. The simulation is carried out by giving fully 3D physiological loading of the hip joint under normal walking conditions. Contact pressure analysis conducted on dry contact condition and meshing with the two-pole method performed to provide a comprehensive contact pressure result. The results show that the total hip arthroplasty model with dimple addition can reduce contact pressure for all phases in one full cycle with average decreased by 15.53% which indicates that adding dimple to the contact surface in the total hip arthroplasty bearing can extend the life of implant use.
