The hip joint is a crucial ball-and-socket joint that consists of the femoral head as the "ball" and the acetabulum as the "socket". It is supported by ligaments that help maintain stability and is vital for activities like walking, running, and sitting. Treatment usually starts with non-surgical methods, but if these fail, surgical options like total hip arthroplasty (THA) may be required. The 20th century saw advances in metals like stainless steel, cobalt-chromium alloys, and titanium, which enhanced implant performance. This research evaluates the performance of titanium alloys, stainless steel, and gold in hip implants. Titanium alloys were chosen for their strength and biocompatibility, while stainless steel was included for its strength. Gold, despite its lower strength, is noted for its biocompatibility. The study utilized specific design software to analyze metal alloys for their mechanical properties. Challenges in assessing larger-scale properties were addressed using the finite element method. Tests were conducted on implant samples to study their reaction to force and Pressure, with results showing the superior performance of one titanium alloy. The development of new titanium alloys is very important.
