Assessment of Cobalt, Stainless Steel, and Titanium Alloys for Knee Joint Prostheses, A simulation-based study

This research investigates the mechanical properties of Cobalt, Stainless Steel, and Titanium alloys for their applications in knee-joint prosthetics. Through static and dynamic testing, parameters such as displacement, stress, and strain were evaluated to determine the appropriateness of each material under various load conditions. Although Cobalt alloy exhibits considerable strength, its application is constrained by toxicity concerns and relatively low impact resistance. In contrast, Stainless Steel demonstrates equivalent strength to Cobalt while lacking toxicity, thereby exhibiting superior impact resilience. Ti-۱۰V-۲Fe-۳Al alloy, recognized for its exceptional flexibility and biocompatibility, is particularly suited for scenarios involving dynamic loading. In conclusion, both Stainless Steel and Titanium are advocated for knee implant utilization, as they provide an optimal balance of strength, safety, and adaptability, thereby contributing to enhanced implant durability and improved patient quality of life. It is worth mentioning that this research is based on software simulation and does not have practical tests, and it can be a suitable research field for researchers.
