An internal analysis by Johnson and Johnson, the makers of the recalled Depuy hip implants has been publicly released through court documents and reveals that the company projects that as many as 40% of the implants used will fail within 5 years in the patients who received it.
According to an article in today’s New York Times, “About 93,000 patients worldwide received an A.S.R., about one-third of them in the United States.” Assuming that 40% of them could fail, the A.S.R. Hip Implants (Articular Surface Replacement) could fail with five years for over 12,000 Americans who received the implant. The implants were recalled by Johnson and Johnson in 2010. So far about 9,000 cases have been filed between federal court in Ohio and state court in California. The first cases go to trial this week in California.
