NEW YORK (Reuters Health) - Being overweight is known to increase the risk of needing a knee replacement, but a new study finds that knee replacement surgery may also raise a person's risk of gaining weight.
Analyzing the medical records of nearly 1,000 knee-replacement surgery patients, researchers found that 30 percent of them gained five percent or more of their body weight in the five years following surgery.
One possible explanation for the counterintuitive results, experts said, is that if people have spent years adapting to knee pain by taking it easy, they don't automatically change their habits when the pain is reduced.
