N2 - Hip implants are available in various shapes and sizes. This study aims to select the better hip implant stem design and the optimal material that can be used for the implant. For all the material combinations, radial clearance of 0, 0.1, 0.2, and 0.3 had been given between each of the junctions. Analytical calculation using Hertz contact stress formulation to find the contact pressure has been employed for a load of 2300N, which goes hand in hand with the Finite element method (FEM). The results showed that the optimal combination consists of a CoCr alloy stem, femoral head, and cup material, paired with a UHMWPE liner, for the most effective performance. This study thoroughly evaluates various hip implant options and offers important insights into their effectiveness. The results of this research will assist in choosing the most appropriate hip implant design and material, leading to better patient outcomes and advancements in medical technology for the betterment of mankind.
