ATLANTA (AP/WAOK) –   A new study suggests there may be a connection to knee replacement surgery and gaining weight.

Researchers at Virginia Commonwealth University analyzed the medical records of nearly a thousand knee-surgery patients.

They found that 30-percent of them put on five-percent or more of their body weight in the five years following surgery.

Experts say one possible reason my be that people who’ve spent years adapting to knee pain by taking it easy, don’t automatically become more active when the pain is reduced.

The study is published in the journal “Arthritis Care and Research.”
