摘要：

Bone resorption around cemented acetabular cup caused failure in the long tenure. This study aims to investigate the effect of different implant materials on bone remodelling around the cemented acetabular cup. Finite element (FE) models of intact and implanted pelvic models were established using CT-scan data sets. Three combinations (acetabular cup-femoral head) of implant materials, UHMWPE-CoCrMo, CoCrMo-CoCrMo, and alumina-alumina ceramic, were considered to predict the effect of implant materials on bone remodelling around cemented acetabular cup. Less bone resorption was observed for UHMWPE acetabular cup. Bone remodelling was nearly similar for the ceramic and metallic cup. Considering the bone remodelling scenario, the results of the current study stated that ceramic could be a good alternative to metallic implant in the cemented acetabular cup since ceramic has better wear resistance property than metal.
