A Texas jury has ordered pharmaceutical giant Johnson & Johnson to pay over $1 billion to six plaintiffs who said the implant maker hid flaws in its hip implants.

A federal jury in Dallas on December 1 concluded that J&J’s DePuy Orthopaedics unit knew about the risk that its Pinnacle hip implants would fail but did not warn patients or doctors.

According to plaintiffs, metal debris from the Pinnacle metal-on-metal hips entered the bloodstream and caused a number of complications that led to implant failure.
