In the surgeon Themistocles Gluck implanted the first artificial knee joint, made of ivory and nickel-plated steel, into a patient in Berlin. The first artificial hips followed in In the following years, materials and techniques were improved to such an extent that joint replacement surgery could be safely and successfully carried out. The British orthopaedic surgeon Sir John Charnley developed the prototype for the hip endoprostheses still used today. The prototype consisted of a small metal head, and a socket made of Teflon, which was later substituted with polyethylene. Bone cements based on PMMA have been used since then to anchor endoprostheses. This was followed in by the first bone cement with added antibiotic to protect the endoprosthesis against infection.

Knee joint replacement is a surgery to replace a knee joint with a man-made artificial joint. The artificial joint is called a prosthesis. Damaged cartilage and bone are removed from the knee joint. Man-made pieces are then placed in the knee. You will not feel any pain during the surgery. You will have one of these two types of anesthesia:. After you receive anesthesia, your surgeon will make a cut over your knee to open it up.

Like knee or hip replacement, a new hand or wrist joint can help you get back into the action. Chances are, you know someone who has a new knee or hip joint. Maybe you have one yourself. But you probably don't know anyone sporting a high-tech wrist or finger joint. Joint replacement of the hand is less common than surgery to replace a knee or hip joint, partly because the intricate bone structure and small size of the hand make the procedure more challenging. Still, surgeons have been replacing hand joints in selected patients since the s.

Joint replacement parts are made of plastic and metal that aren't reactive to the human body. Artificial joints are made out of a combination of materials including metal, ceramic, and plastic. The components of an artificial knee joint are made from some combination of hard polished metal, hard ceramic and tough, slick plastic. The same materials are used for hip implants—the stem portions of most hip implants are made of metal alloys, the ball portions are made from metal alloys or polished ceramic, and the acetabular sockets are made from metal, polyethylene plastic , a combination of polyethylene backed by metal or ceramic. All materials that are used to construct artificial joints need to meet the following criteria:.

Every day, people all over the world need to get some form of joint replacement. In the United States alone, a whopping one million people will have a total joint replacement procedure, and the numbers are expected to rise above four million per year in the next two decades. For an aging population coupled with more active lifestyles, precision-made replacement joints composed of specialized materials have created a surge in joint replacement surgeries.
