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. How many people each year have joint replacements?
2. What do doctors use to replace damaged joints?
3. Which are the most common joints to be replaced?
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. About how many people have joint replacements each year, and what do doctors use to replace a damaged joint?
2. Which are the most common joints that are replaced and how long does an artificial joint generally last?
3. How many methods do doctors use to replace damaged joints, and which method do you think is the best for joint replacement?

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. 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 how many people have joint replacement a year, what do doctors use to replace damage joints, and which joints are most commonly replaced?
2. Explain how long artificial joints generally last, and what bone cement fixation is.
1. Explain how many people have joint replacement a year, what do doctors use to replace damage joints, and which joints are most commonly replaced?
2. Explain how long artificial joints generally last, and what bone cement fixation is.
3. Explain why joint replacement might be unnecessary in the future.
