The issue of faulty metal hip replacements implants came to the knowledge of Johnson & Johnson officials in the year 2008 and it was almost a year later that the company stopped making the joints. Almost after two years, the company finally recalled its product, reveals the documents unsealed in a California state court.

The below news is discussing about the internal analysis that was done by J&J in the year 2011, the findings of which have recently suggested that the company is expecting approx 36% of the devices to fail within five years.

The above facts came to light by the documents that were filed in the first personal-injury lawsuit involving the implants that is scheduled to go to trial.

According to the information provided in the papers, the faulty devices i. e. the artificial hip sockets and balls together known as the Articular Surface Replacement or ASR system were made by J&J's DePuy Orthopaedics unit. The analysis performed is suggesting that the implant is at higher risks of failing prematurely over the next few years, which could affect thousands more patients along with those, who are already facing the painful and costly procedures of replacement. The trial in the case will begin on Friday in California Superior Court in Los Angeles.
