Which category of biomaterials is often used in orthopedic applications?

The category of biomaterials often used in orthopedic applications is metals. This is due to several important properties that metals possess, such as excellent mechanical strength, toughness, and wear resistance, which are essential for load-bearing applications in the body. Orthopedic implants, such as joint replacements and fixation devices for bones, need to withstand significant forces and provide stability over long periods.

Common metals used in orthopedics include titanium and stainless steel, which are favored for their biocompatibility and ability to integrate well with bone (osteointegration). The ability to impart support in a biological environment where the mechanical demands are high makes metals particularly suited for these applications. Moreover, their ability to be manufactured into various shapes and sizes adds to their versatility in meeting specific clinical needs.
