Johnson & Johnson DePuy ASR Hip Replacement Implant Lawyers
Our firm is investigating reports of early failure of the DePuy ASR metal-on-metal hip replacement system.
Johnson & Johnson’s DePuy Orthopaedics unit was already phasing out the ASR hip replacement implant system when it finally acknowledged in March 2010 that the device was prone to early failure. By that time, the US Food & Drug Administration (FDA) had received hundreds of reports describing early failure of the DePuy ASR hip implant system.

Hip Replacement Implant Injury Lawyers
If you or a loved one has experienced a serious and debilitating injury because of a defective hip implant, you are not alone. Over the past several years, hip implants made by major manufacturers, including Stryker Orthopedics, DePuy, and Zimmer, have all been associated with serious safety problems. If you have experienced complications following hip replacement surgery, our hip implant injury lawyers want to hear from you today.
The ways in which the DePuy ASR hip implant can fail include: Loosening of the various components in the implant;
- Necrosis (premature death of body tissue) or soft tissue damage due to exposure to metal particles due to wear of the implant;
- Elevated cobalt and chromium levels in the blood due to wear of the implant.
Symptoms suffered by patients who have been implanted with the DePuy ASR hip implant were outlined to include:
- Severe pain in implant, radiating into the groin and/or back
- Radiographic changes including loosening and lysis (dissolution or destruction of cells) or osteolysis
- Fluid collections and cystic or solid masses around the joint
Our hip implant injury lawyers know how difficult life can be for people suffering as a result of one of these defective devices. Premature failure, faulty components and even contaminated devices have prompted hip implant manufacturers to issue safety alerts and recalls for their products. In most cases, patients injured by a faulty hip implant have to undergo additional surgeries to correct the problem, and even then, full recovery is not guaranteed.
If you have suffered premature failure of a hip implant, severe inflammatory reactions, or muscle, bone or other tissue damage associated with a hip implant, you may be entitled to compensation for medical bills, lost wages, and pain and suffering. Our hip implant injury lawyers are offering free consultations to victims of these devices. We urge you to contact us today to protect your legal rights.
Recent Hip Implant Complaints and Recalls
Defective hip implants have been the subject of numerous safety alerts and recalls over the last several years. In September 2001, the Food & Drug Administration (FDA) announced that Biomet and seven other U.S. medical device firms would recall hip implants because of problems with a component called the zirconia ceramic femoral head. This component, which is the ball portion of hip implants, was prone to fracture and often required surgical replacement.
The component was manufactured by St. Gobain Desmarquest of France, and used by Biomet, as well as Apex Surgical LLC, DePuy Orthopedics Inc., Encore Orthopedics Inc., Osteoimplant Technology Inc., Smith & Nephew Inc., Stryker Howmedica Osteonics and Zimmer Inc. The component was used in hip implants manufactured since January 1998 up until September 2001.
Symptoms of a fractured zirconia ceramic femoral head include hip pain, a sensation of grinding or limitation of motion. The fracture was sometimes preceded by an audible pop. The at-risk hips tended to break between 19 and 28 months after implantation.
The Zimmer Durom Cup is another hip implant component that has been associated with serious and painful complications. In July 2008, Zimmer Holdings announced it was suspending sales of the Durom Cup hip implant component due to a high number of patient complaints. X-rays of patients who received defective Durom Cups showed that the socket was separating from bone, rather than fusing with it. Many Durom Cup recipients reported that they were in much worse shape after their surgery than before.
Hip implants made by Stryker Orthopedics have also been the subject of patient complaints. In 2008, the company announced it was recalling two hip implant components made under the company’s popular Trident line – the Trident Acetabular PSL Cup and the Trident Hemispherical Cups. Acetabular Cups are used in the socket portion of replacement hip components. Prior to the recall, the PSL version was the most commonly used Stryker cup in the U.S. The Trident Hip Implant cup recall was implemented by Stryker amid concerns that these components could be contaminated with manufacturing residuals” at levels that exceeded company standards.
In November 2007, Stryker received a warning letter from the FDA regarding complaints about components made at its Mahwah, New Jersey factory since 2005. Those complaints included hip joints that did not fit properly, an issue which caused recipients to experience a range of problems, including pain, difficulty walking and “squeaky” joints. Some patients even reported that pieces of their implants had broken off, and others had worn unevenly. The FDA warning letter said that the deficiencies uncovered at the Mahwah facility had contributed directly to the manufacture of these faulty hip implants.
In March 2010, Johnson & Johnson’s DePuy Orthopaedics unit warned that its ASR artificial hip implant had been associated with a high failure rate. The warning from DePuy followed more than two years of reports that the device was failing in patients only a few years after implant, requiring costly and painful replacement operations. Since the beginning of 2008, the FDA had received about 300 complaints on the ASR involving patients in the U.S.
Just months before it issued the ASR warning, DePuy announced the device was being phased out of the market. The company claimed the decision was made because sales of the ASR were declining.
The ASR is a type of device known as a metal-on-metal implant. All major orthopedic makers, including Zimmer Holdings, Smith & Nephew and DePuy Orthopaedics, market metal-on-metal hip implants. While this type of hip implant has been used in about one-third of all hip replacements performed annually in this country, many of the nation’s leading orthopedic surgeons have reduced or stopped using all-metal implants because of concerns that they can cause severe tissue and bone damage.
The cause of the problem isn’t entirely clear, but studies in recent years indicate that in some cases all-metal devices can quickly begin to wear. This creates a large amount of metallic debris that is absorbed into a patient’s body. The metallic debris can cause inflammatory reactions that lead to pain in the groin, death of tissue in the hip joint and loss of surrounding bone. The limited studies conducted so far on metal-on-metal hip implants estimate that 1 to 3 percent of implant recipients could be affected by the problem.
