Knee problems are very common and can occur in people of all ages. Knee problems can interfere with many things, from participation in sports to simply getting up from a chair. This can have a big impact on your life including chronic pain and difficulty walking.
Your knee joint is made up of bone, cartilage, ligaments and fluid. Muscles and tendons help the knee joint move. When any of these structures is hurt or diseased, you have knee problems.
The most common disease affecting the knee is osteoarthritis, where the cartilage in the knee gradually wears away, causing pain and swelling. Injuries to ligaments and tendons also cause knee problems.
