Prosthesis refers to an artificial device replacing or augmenting a missing or impaired body part. Total Hip Replacement (THR) is a widely used solution for arthritis, hip fractures, and osteoporosis, significantly improving mobility and reducing pain. In this study, two hip prostheses with identical dimensions but different material combinations-Tantalum-TZP and CoCrMo-TZP-were analyzed using Finite Element Analysis. Various parameters like displacement, stress distribution, and strain were evaluated for different human activities. The results indicate that Tantalum-TZP prosthesis exhibited...
