Level#2
Nearly one-and-a-half million people have joint replacements each year. Doctors use an artificial joint to replace the damaged joints. Most common are hip and knee replacements. Artificial joints generally wear out within ten years. Bone cement fixation is one method used for joint replacement. The artificial joint is placed between two bones. Bone cement sets it in place. The new joint is designed to function like the natural joint. In another method, bone cement is not used. The artificial joint and the bone are designed to fit and lock together exactly.

Artificial joints may not be needed in he future. Recently, engineers at the University of California have developed an artificial tissue that works like real cartilage. This tissue may help repair injured or arthritic joints. The artificial tissue may also be able to bring back flexibility to people with damaged joints.
1. What do doctors use to replace damaged joints?
2. Explain which joints are most commonly replaced and how long do replacement joints last.
