ABSTRACT
There have been great advances in extending how long an artificial joint will last. The current investigation deals with one of the most important parameters in controlling the life span of artificial knee, which is the thickness of the polyethylene layer of (Tibia Tray), of artificial knee joint. The current Sigma design used at hospitals, which utilizes polyethylene layer thickness of 4 mm proved to be adequate not only for strengthening mostly all constituents of artificial knee joint, but also the surrounding bones.
Keywords: Finite-element model, Artificial knee design.
