In present research work a numerical investigation of customized hip replacement implant is presented. The long-term stability of hip implants depends on the material selection and on the loads acting across the joint. In this context, an attempt was made to optimize acetabular liner material in the perspective of minimum stress that eventually enhances the prosthesis life and minimizes the wear of counter bodies. 3D CAD model of Hip joint has been successfully modelled using CT scan data with the help of MIMICS 21.1 and subjected to analysis, depending on the anatomical data of the patient which is suffering from osteoporosis and pain and consider for THR with cemented joint. The patient specific Hip joint modelled in SOLID WORKS-20. Tribological testing (ASTM F732) being done by Bio-tribometer to evaluate the specific wear rate and Coefficient of friction and it was found that UAG has less specific wear rate which is 1*10−8 mm3/Nm and Cof which is 0.0125 with respect to other material. These sample are tribological tested using simulated body fluid (SBF) environment, which is similar to human blood plasma. Tensile testing (ASTM D638) done by UTM and found that CPLA has highest elastic modulus which is 2637.29 and UAG has highest poisson ratio which is 0.47. The finite element algorithm is used to simulate the prosthetic hip joint implant using student Version of ANSYS 22.0. The finite element analysis is done to evaluate the Von mises stresses, Total deformation and contact pressure for different acetabular liner material. A hip joint model is made up of femoral stem, femoral head, acetabular liner and acetabular head. The modified Archard’s wear law is used to calculate wear. The results show that wear is least when UAG is used for liner with 0.12 mm wear at single point for a average life of 15 years.
