All-metal hip replacements fail at high rate

More than 231,000 Americans get their hips replaced each year, but the new hips made entirely of metal have been failing at an unusually high rate.

Many of the bad ones are made by Johnson and Johnson.

They were recalled in 2010, but according to the New York Times, the company may have known of the problem way back in 2007.

It's believed that metal rubbing on metal can cause particles to shave off and enter the bloodstream.

That can cause all kinds of symptoms not associated with the hip, including heart problems and fatigue.
