CHICAGO (AP) -- A new study shows that hip replacements are more likely to fail in women than in men.
Researchers found that a small number of the hip implants failed overall, but women were 29 percent more likely than men to need a repeat surgery within the first three years.
Researchers looked at more than 35,000 surgeries at 46 hospitals in the Kaiser Permanente health system. The study is being published Monday in JAMA Internal Medicine. It was funded by the U.S. Food and Drug Administration.
Some experts say more research is needed to determine which models of hip implants perform best in women.
Women make up the majority of the more than 400,000 Americans who have full or partial hip replacements each year.
