ABSTRACT
Over the years, orthopedic implants have been designed to restore the normal physiological function and mechanical stability of diseased or damaged musculoskeletal tissues. Typically, this has been accomplished through the use of high strength metals such as stainless steel, titanium, cobalt chromium alloys, and nonresorbable polymers such as polyethylene. These materials have been used to create a wide array of orthopedic devices designed to replace human joints and stabilize severe fractures. Although these structural implants have functioned adequately in their restorative role, the surgeon’s preference would be to minimize or eliminate the use of permanent materials in the body and have the site heal itself.
