Abstract:

Ultra-high molecular weight polyethylene (UHMWPE) has been used as a bearing material in total joint replacements due to its relevant properties and biocompatibility since 1962. Acetabular cup in total hip replacement and tibial component in total knee replacement are generally fabricated from UHMWPE. The use of UHMWPE in joint replacements is well established and its demand is increasing in young and active patients. The life span of the artificial joint can be increased by enhancing the mechanical properties of UHMWPE. Although this procedure is widely practiced in Pakistan, it lacks indigenous manufacturing capabilities of artificial joints. In this study, relevant properties of UHMWPE were enhanced, and UHMWPE component was indigenously fabricated. The addition of filler material in UHMWPE is an effective way to enhance its relevant properties. Reduced Graphene Oxide (rGO) was selected as a filler material as it will lead to better wear resistance, toughness, and thermal stability. Graphene oxide (GO) was synthesized by Modified Hummer’s Method, and it was thermally reduced to obtain rGO. GO and rGO were characterized by Fourier Transform Infrared spectroscopy (FTIR) which confirmed their synthesis. The rGO/UHMWPE mixture was prepared by adding 0.7 wt% of rGO employing dry mixing method. Standard samples of the nanocomposite were manufactured by compression molding. Various mechanical tests were performed on the sample which shows tensile strength increased by 19.3% while impact strength decreased by 31%. Machining operations were performed on the sample to achieve the required dimensions of a tibial component. The fabricated tibial component with improved properties provides an effective and economical approach to meet the requirements of the indigenous market
