FED PROBE: Government prosecutors are looking into how Johnson & Johnson marketed its DePuy ASR hip replacements, which the company recalled in 2010 because one in eight had to be replaced prematurely.
COMPANY COOPERATING: J&J says it's turned over all documents requested by the government. It's denied allegations it knew about problems with the hip replacements well before it stopped selling them and recalled the remaining products.
DEJA VU: J&J previously was ordered to stop selling another hip system for unapproved uses. In 2007, it paid about $85 million to settle allegations it bribed surgeons to choose its joint replacements.
