If you underwent hip replacement surgery, you may have received one of the implants made by DePuyOrthopaedics, a subsidiary of Johnson & Johnson. The ASR XL Acetabular System, the ASR Hip Resurfacing System and the Pinnacle hip system with metal liner are metal-on-metal hip implants that were manufactured by DePuy. The devices were approved for sale through a medical device clearance process. This process allows manufacturers to market and sell medical devices without any premarket testing or clinical trials, provided the manufacturer can show that the device is “substantially similar” to a device already on the market. Various dangers with the DePuy devices later surfaced.
Research indicates that the DePuy hip will fail in one in five patients within four years. After six years, shockingly, almost half of all patients with the device will experience a failure. As a result, DePuy issued a warning about the devices and then finally recalled them in August 2010. Doctors found that fragments from the ASR hip implants’ metal surfaces were fretting, causing swelling, infection, fever, pain and the inability to walk in many cases. The fretting and corrosion of the metal also resulted in the release of chromium and cobalt metal ions into the body, resulting in a condition known as metallosis. DePuy received hundreds of reports of device failures and complaints before recalling these hip implants, yet over 93,000 patients were implanted with the DePuy ASR hip system in the United States before the recall. Thousands have since sued DePuy. Many experts believe that Johnson & Johnson should have recalled the defective DePuy ASRimplants far earlier. In November 2013, after a number of “bellwether” (“test”) trials went forward against DePuy for the defective ASR hip system, Johnson & Johnson agreed to pay approximately $2.5 billion to patients injured by their ASR implants to resolve the bulk of pending lawsuits.
