The objectives of this thesis are to propose the optimum safe zone orientation for Metal-on-Polymer (MoP) of THR, to study mechanical analysis based on the safe zone orientation and to suggest a composite material replacement for the acetabular cup.

The mechanical analysis of 36mm femoral head diameter using 5% Epoxy-Ultra High Molecular Weight Polyethyelene (EpUHMWPE5) at the corresponding safe zone orientation showed a reduction of 5.0388MPa, 4.5042MPa and 0.018344mm in terms of contact pressure (MPa), Von-Mises stress (MPa) and total deformation (mm), respectively.
