Biomaterial Selection for Knee Prosthesis Using the TOPSIS Multi-Criteria Decision-Making Method

The choice of biomaterial for the knee prosthesis is an important consideration when creating artificial knee joints for patients who require knee replacement surgery. The longevity, biocompatibility, and long-term success of knee prosthesis are significantly influenced by the biomaterials chosen. Several essential qualities should be present in the optimum biomaterial for knee prosthesis. First and foremost, it needs to be extremely strong mechanically so that it can support and stabilise the knee joint while withstanding the loads and forces involved in regular activities. The second requirement is that it be biocompatible, which means that the immune system won't reject it or have any negative reactions to it. This guarantees that the implant will blend in without causing irritation or discomfort to the surrounding tissues. Metals, ceramics, and polymers are often utilised biomaterials in knee prostheses. Research on the choice of biomaterial for knee prostheses is important because it enhances patient outcomes, lengthens implant life, assures biocompatibility and safety, propels material science developments, allows for individualised treatment plans, and fosters cost-effectiveness. Research on knee prosthesis biomaterial selection is essential for optimising biocompatibility and safety, enhancing patient outcomes, advancing material science, enabling individualised treatment plans, and enhancing cost-effectiveness. These studies advance orthopaedic science and help people with knee joint problems and the development of improved knee prostheses.
