How Do Joint Replacements Work?

Orthopedic surgeon Willard Moore, MD discusses the resurfacing process of joints during surgery. "In general, when we think about a joint replacement, resurfacing is probably a better term. We’re basically shaving off the ends of the bones to get rid of that worn out cartilage and putting a new artificial surface. Usually that’s either metal or polyethene, which is a fancy plastic. For a hip replacement, we’re replacing the socket which is part of the pelvis and the ball which is the top of the femur. It’s a new ball and socket joint to replace the one that was worn out.

On a knee side, we’re resurfacing the joint. We put a metal cap on the end of the thigh bone, we put a metal tray on the shin bone side and then we usually resurface the back of the kneecap as well. We shave the back of the kneecap and put a polyethene or plastic lining there. We resurface the whole knee so you can’t have arthritis anymore."
