Thousands of people have knee surgery. A new study from Finland says many of these people might be wasting their money. The surgeons who did the study said some knee surgery can make knee problems worse and not better. The surgeons spent 10 years studying knee operations. They found that surgery on knee cartilage rarely worked. The doctors said many of these operations were unnecessary. They added that some operations increased cartilage damage. One doctor said that patients who have this procedure "have more pain".
In happier knee news, doctors from a university in the USA have found a new way to help long-term knee pain. One doctor has performed simple operations. These involve reducing the flow of blood to painful areas in the knee. Less blood in those areas reduces swelling and pain. The doctor says her method is better than medicine and physical therapy. She also believes people can avoid knee surgery and knee replacements. She said her method could "provide years of relief" by reducing pain inside the knee joint. She said 70 per cent of patients have great results.
Back to the knee surgery lesson.
