The objective of this research work is to analyze the biomechanical behavior (stress and deformation) of cementless THR made up of β-phase Ti alloy at static and dynamic loading conditions using the finite element modeling (FEM). In the present research work, the surface of β-phase Ti based cementless THR is modified or treated by powder mixed electric discharge machining (PMEDM) process. PMEDM pro-vides a vehicle to interface implant with large scales cell and tissues. In other words, PMEDM promotes bone ingrowth (osseiointegration). In this paper, a three dimensional FEM model of CT-scanned bone of a patient and implant was constructed using ANSYS 14 software. The bonded contact was used to sim-ulate the full bone ingrowth and long term stability of THR. The study predicts the potential risk of fail-ure of the implant at static and dynamic loading condition. The results obtained from this study indicate that no risk of failure of implant arises further the results are helpful for the prosthesis surgeons to un-derstand the biomechanical behavior of the β-phase Ti based cementless THR. The results clearly indi-cate that PMEDM process can be used as a surface modification technique for Ti based bio-implant in future.
