A common type of knee surgery to repair the meniscus, which cushions the bones of the knee, is no more effective than fake surgery, at least in the first year, according to a study published in the New England Journal of Medicine.
For the study, researchers looked at 146 volunteers at five medical centers in Finland, who had knee pain that appeared to be caused by the wear and tear of the meniscus. None of them had a recognized injury or osteoarthritis, as both of those situations have already been proven ineffective for surgery.
Researchers say the study shows that there is no quick fix for this kind of knee pain. But, some doctors disagree with the findings, saying that there are many more factors that go into whether someone should have surgery, and this study doesn't explore those.
