The hip joint serves as a crucial anchor for strength and stability within the human body. Factors such as aging or unexpected incidents may necessitate either partial or complete replacement of this joint. Hip arthroplasty (HA) emerges as the surgical solution, involving the substitution of a damaged or fractured hip. An array of parameters including size, material composition and shape must be carefully considered to determine the optimal implant that seamlessly fits the patient's needs. In this work, finite element analysis is employed to simulate both the femoral stem and the femur. Stress and deformation serve as critical mechanical metrics in assessing the efficacy of the implant. Meanwhile, the durability and performance of the implant depends on the design and choice of materials. The primary objective of this research is to identify the most appropriate material for the hip stem through experimentation.
