Knee Replacement (Visit Resource)
Definition Knee replacement is a procedure in which the surgeon removes damaged or diseased parts of the patient's knee joint and replaces them with new artificial parts. The operation itself is called knee arthroplasty. Arthroplasty comes from two Greek words, arthros or joint and plassein, "to form or shape." The artificial joint itself is called a prosthesis. Most knee prostheses have four components or parts, and are made of a combination of metal and plastic, or metal and ceramic in some newer models.
