ABSTRACT: As a human getting older there are so many health related problem occurs at the older age naturally, and they are not so easy task to cure all the diseases occurred. But also some of them are curable, for such curable condition here discussed a knee joint issue that has the disease called Degenerative arthritis it’s a condition where occurs in-between the femur and tibia parts are affects the line cartilage of the joint which results drastic harm to the joint leads to serious injury to the person. This disease affected person can experience severe pain at joint and it resist the knee joint movement which results to the patient unable to walk freely and in some crucial condition patient unable stand and small move also impossible. For this condition it has a solution called the surgery, yes! It has a knee replacement surgery which includes damaged parts are replaced with the prosthetic parts. And the design and modeling of the joint is completely based on the patient’s condition at the joint. If the pain is drastic the whole knee joint is replaced, if not for small injuries the coat materials are designed as cap materials for the knee joint. By the available literature its known that the materials are used for this surgery are the bio metals this metals are have main significance in prosthesis. Because these bio metals have the bio compatibility means that they have the properties like high chemical stability, non corrosive and non toxic these are main properties to select the prosthetic material. And where these materials are also have the high stress loading conditions. The modeling and design of the knee joint is done based on available literature source in Solid Edge software and the knee joint is subjected to different body temperature condition to know the thermal behavior. And the materials applied for analyzing purpose are like the whole joint is applied with Structural Steel as first, Polyethylene as second and at third combined material is analyzed means the material applied separately i.e. Aluminum alloy for Femur and Polyethylene for Tibia. And three sets are analyses in software (ANSYS 18.1) to investigate the Total heat flux and Total directional heat flux.

Keywords--Finite element analysis (FEM), Knee Joint, Degenerative arthritis, Total heat Flux, Total Directional Heat Flux.
