Finite element modeling and analysis of hip joint prosthesis with modular stem

The Total Hip joint Replacement (THR) was a surgical procedure where by the diseased cartilage and bone of the hip joint is surgically replaced with an artificial material. The success of implantation depends on method, material and size of implant used. The present work focused to study the stress...
