Topological Optimization of Ti-6Al-4V Knee Prostheses Through Lattice Structures for Enhanced Mechanical Performance

In this study, we performed a topological optimization on a knee prosthesis made of Ti-6Al-4V titanium super alloy using metallic additive manufacturing. The optimization was done using nTopology software, wherein lattice structures were incorporated within the femoral component to reduce its weight while maintaining adequate mechanical strength. A comparative analysis of the prosthesis’ mechanical strength with and without optimization was conducted. Our simulation results, obtained through ANSYS, reveal the advantages of topological optimization in the medical industry.
