Researchers tracked 665 people who had knee or hip replacement surgery and measured how much their pain improved over six months using detailed questionnaires before surgery. They found that people with fibromyalgia characteristics—a condition where the body amplifies pain signals—experienced significantly less pain relief after surgery, even if they didn't have a full fibromyalgia diagnosis. The strength of fibromyalgia traits was the single best predictor of surgical failure: for every point higher on the fibromyalgia scale, patients were 18% more likely to not achieve adequate pain relief. This relationship held true regardless of other factors like depression or anxiety, meaning fibromyalgia traits independently caused poor outcomes. This matters because doctors can now screen patients before knee and hip surgery to identify who might not benefit as much from the operation, allowing them to set realistic expectations, prepare patients psychologically, or consider alternative treatments.
