A hip prosthesis manufactured by Johnson & Johnson (JNJ) DePuy unit falls short of its expectation in the United Kingdom as frequent as 49 percent of the time, or four times what the company cited DePuy hip recall in 2010, a British orthopedic group stated. The British Hip Society and the British Orthopedic Association affirmed this week that data on the ASR XL Acetabular from four surgeons show that the rate of revision operations has gone up from 21 percent after four years to 49 percent within just six years.

"It's probably the best indicator so far of what the failure rate is likely to be," John Skinner, an orthopedic surgeon and president of the group’s authority on metal bearing hips, declared in an interview over the phone. "As far as I can tell, it's reliable." Skinner said that the information has not been peer-reviewed as the publication requires.

The DePuy hip recall encompasses the ASR XL and the ASR hip resurfacing system in August 2010. During that time, the company mentioned unpublished data from the National Joint Registry for England and Wales saying that 13% of ASR XL patients required revision surgery in five years, and 12% of patients with resurfaced hips required second operations also within five years. Both devices utilize balls of metal and sockets to replace the unhealthy hips. The surgeons did not report on the resurfacing system in the report.

The plaintiffs have introduced product liability, negligence and failure to warn claims against DePuy for the failed devices, and seek out medical expenses, lost wages and damages for their pain and suffering. In excess of 350 lawsuits have been combined in federal court in Ohio, and over 220 are pending in California state courts. Another collection of cases are pending before a court in New Jersey.

The statement by the British surgeons "suggests that DePuy has a bigger problem on its hands than it has acknowledged," said Lexi Hazam of Lief Cabraser Heimann & of Bernstein LLP in San Francisco, who represents clients in trial of hip DePuy hip recall lawsuits.
