LONDON (AP) — British officials say some people who receive metal hip replacements may need a replacement hip seven years later. According to a National Joint Registry of England and Wales report released this week, almost 14 percent of patients who got an all-metal replacement needed the joint removed or replaced after seven years. That compares with just three percent of patients who got a joint made of plastic and needed a replacement within the same time.
The U.K. registry includes records from about one million people who had hip, knee, and ankle replacements and is the world's largest joint database. Last year, a report by a division of Johnson & Johnson on the failure rate of one brand of metal hip replacements led to its recall by the U.S. Food and Drug Administration.
