摘要: The increasing trend of total knee replacement (TKR) revision surgery, which is associated with aseptic loosening, makes it a challenging research subject. concern loosening can be partially improved by selecting the optimal materials for TKR components. Therefore, this paper considers selection best material among set alternatives femoral component through multi-criteria decision making approach. comprehensive VIKOR method was used to select optimum material, and systematic technique sensitivity analysis weights introduced find more reliable results. obtained ranking order suggested use new over existing ones. Porous dense NiTi shape memory alloys were ranked first second respectively.
