Femoral prostheses are pivotal in improving the quality of life for individuals suffering from hip joint-related issues, such as osteoarthritis and hip fractures. The design of these prostheses is critical to ensure long-term stability, functionality, and patient comfort. This study investigates the innovative application of functionally graded lattice structures to enhance the performance of femoral prostheses. Functionally graded lattice structures are characterized by varying material properties within the lattice, allowing for tailored mechanical properties to meet the specific demands of different regions within the prosthesis. This research aims to optimize the design of femoral prostheses by incorporating functionally graded lattice structures such as triply periodic minimal surface (TPMS). The current research encompasses a comprehensive review of existing femoral prosthesis designs and materials, biomechanical analysis, and computational modeling. Finite element analysis (FEA) will be employed to simulate the behavior of the functionally graded lattice structures under various loading conditions, providing insights into their mechanical performance. Furthermore, this study aims to investigate the biocompatibility and osseointegration potential of functionally graded lattice structures, ensuring that the prostheses not only withstand mechanical stresses but also promote the natural healing and integration processes of the surrounding bone tissue. The outcomes of this research include the development of novel femoral prosthesis designs that offer improved mechanical stability with reduced stress shielding and enhanced compatible nature. These advancements have the potential to significantly enhance the quality of life for individuals requiring femoral prostheses while reducing the risk of complications associated with traditional designs.
