There are approximately 800,000 hip and knee replacements performed every year in the United States.1 The technique of joint replacement typically uses metal and plastic implants to replace the damaged sections of bone and joint cartilage. The joint itself is not replaced, only the damaged bone and cartilage surfaces.
Total knee replacement replaces damaged cartilage and bone with an artificial surface. The replacement implants include a metal alloy on the end of the femur (thighbone) and polyethylene (plastic) on the tibia (shinbone) and patella (kneecap). The implants create a new, smoothly functioning joint that prevents painful bone-on-bone contact.

If you have questions regarding Signature™ Personalized Patient Care, please speak with an orthopedic surgeon. Biomet is a manufacturer of orthopedic implants and does not practice medicine. Only an orthopedic surgeon can determine what treatment is appropriate. Individual results of total joint replacement, including implant longevity, will vary, depending on your weight, age, activity level, and other factors. While uncommon, complications can occur during and after surgery. Some complications include, but are not limited to, infection, blood clots, implant breakage, malalignment, and premature wear, any of which can require additional surgery.
