Abstract: Background: Total hip arthroplasty (THA) is one of the most successful health interventions in the last century.However, there have been several reports of dissatisfaction with the hip implant.Most modern implants are manufactured based on Western morphology.This generalized design may not be suitable for all races, particularly Asians, who tend to have a more petite physique and distinct femoral anatomy. Methods and Results:This study evaluated the biomechanical properties of a newly developed local hip implant using the Finite Element method based on ISO 7206-4, ISO 7206-6, and ASTM F2996-20.The implants were analyzed under static and dynamic load, and three different implant materials were used.The results showed that the titanium (Ti6Al4V) implant had the lowest von Mises stress, the cobalt-chrome (Co28Cr6Mo) implant had the lowest total deformation, and the stainless steel (SS316L) implant had the highest alternating stress and a lower life cycle.All of the materials have more than 1 (>1) safety factor value, which is considered safe for implant manufacturing.Conclusion: This study offers insights into the performance of various materials under static and dynamic loading conditions, demonstrating that all simulated materials are deemed safe for implant manufacturing.(
