ABSTRACT. Knee joint is important joint in human. This joint is also called as weight bearing joint and stabilizes the body movements. The disease caused to knee joint due to Rheumatoid arthritis, Osteo-arthritis and Traumatic arthritis is called Knee joint failure. The failure knee joint is replaced by artificial components either partially or totally. 3-Dimensional assembly in different orientations of knee joint components are modelled in SolidWorks V6. Analysis in different orientations is performed using Ansys14 software. The early failure (wear and tear) of knee joint implant components is found out by evaluating contact stresses between the Femoral component and UHMWPE. The metallic implant material used in this project is TNTZ (titanium β alloy) and compared with CoCr, Ti6Al4V. It is observed, the contact stresses are less in UHMWPE with TNTZ material is used as compared to other materials.

Keywords: tibial component, femoral component, tibial insert, contact stresses, wear
