Level#1
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.
1. What can you do if you have a damaged joint that no longer works?
2. Which joints are the most likely to be replaced?
3. How long do artificial joints normally last?
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 in not used. The artificial joint and the bone are designed to fit and lock together exactly.
1. How many joint replacements are done a year, and which ones are the most commonly replaced?
2. What is bone cement fixation and how is it done?
3. What is the other method of joint replacement and how is it done?

Artificial joints may not be needed in the 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. Explain what the bone cement fixation method is and how it is done.
2. Why is it that artificial joints won't be needed in the future?
