What is Total Joint Replacement? Pt. 2

Total joint replacements of the hip and knee have been performed since the 1960s. Today, these procedures have been found to result in significant restoration of function and reduction of pain in 90% to 95% of patients.1 While the expected life of conventional joint replacements is difficult to estimate, it is not unlimited. Today's patients can look forward to potentially benefiting from new advances that may increase the lifetime of hip and knee prostheses.

What is Total Joint Replacement?

Total joint replacement is a surgical procedure in which certain parts of an arthritic or damaged joint, such as a hip or knee joint, are removed and replaced with a plastic or metal device called a prosthesis. The prosthesis is designed to enable the artificial joint to move just like a normal, healthy joint. Hip replacement involves replacing the femur (head of the thigh bone) and the acetabulum (hip socket). Typically, the artificial ball with its stem is made of a strong metal, and the artificial socket is made of polyethylene (a durable plastic).
