This study aims to propose lower material consumption of Total Knee Replacement (TKR), by employing Topology Optimization (TO). The objective is to propose a new knee implant design via Topology Optimization. Additionally, this study aims to calculate optimum cost-effective materials for the tibial and femoral components of the knee implant while maintaining the desired mechanical properties. SolidWorks and ANSYS Workbench software are used as tools in this study. Initially, the knee implant design was created using SolidWorks, followed by analysis and topology optimization using ANSYS Workbench. The method involves comparing the mechanical properties before and after optimization and calculating the amount of material saved through the optimization process. According to the findings, optimization may result in a reduction in material consumption of up to 23.96% with a difference of less than 5% in terms of the mechanical characteristics of the original design and the newly optimized design. © 2023 Penerbit UTM Press.
