Are you a victim of the DePuy ASR hip implant recall? Thousands of people across the U.S. were implanted with DePuy Orthopaedic's defective ASR hip replacement system between 2005 and 2010, when it was finally recalled. Many of those patients experienced the premature failure of their DePuy ASR hip implant within just few years of their surgery. Even those patients who haven't yet experienced problems with their DePuy ASR hip implant face an uncertain future.

Failed total hip replacement with revision.

1. Patient with a failed total hip replacement with considerable proximal femoral bone loss, proximal migration of the greater trochanter and breakage of multiple screws distally from the previous interlocking device.

2. Surgeons revised the hip implant with a constrained acetabular component and cemented a proximal femoral replacement into the distal femur.

Attorneys at Parker, Waichman, LLP involved in the DePuy ASR hip implant case are offering a free lawsuit consultation to anyone injured by this defective medical device. If you underwent hip replacement surgery since 2005, and have suffered from unexplained hip, thigh or groin pain, pain with walking, pain rising from a seated position, or pain with weight bearing, you may be the victim of a failed DePuy ASR hip implant. We urge you to contact one of our DePuy ASR hip implant lawyers today to protect your legal rights.

The DePuy ASR Hip Implant Recall

The DePuy ASR Acetabular Cup System first came on the market in 2005. It was cleared by the U.S. Food & Drug Administration (FDA) via a process known as 510(k) approval. This process allows a manufacturer to obtain market approval with very little clinical testing of the device - including no human testing - if a manufacturer can prove it is "substantially similar" to another product already on the market. In 2010, an internal FDA review - ironically released shortly after the DePuy ASR hip implant recall was issued - found numerous flaws with the 510(k) process, prompting the agency to consider changing it.

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

In 2009, DePuy had already announced it would be phasing out the ASR hip implant, ostensibly because of low sales. But by 2008, the FDA had received more than 300 reports of problems with the hip implant, most involving premature failure that required revision surgery. A hip implant should last for roughly 15 years, but many DePuy ASR hip implant recipients were undergoing new surgeries just a few years after implantation.

Then in a letter dated March 6, 2010, DePuy warned doctors that recently analyzed data from Australia suggested that the ASR had a higher-than-expected failure rate when used in traditional hip replacement on certain types of patient. According to the letter, patients of small stature, a group that typically includes women and patients with weak bones, faced the highest risk.

Finally, in August 2010, DePuy issued a worldwide recall for the ASR XL Acetabular Hip Replacement System after data from the National Joint Registry of England and Wales showed that 1 out of every 8 patients (12%-13%) who had received the devices had to undergo revision surgery within five years of receiving it. By then, more than 93,000 patients worldwide were fitted with an ASR hip implant. It is believed that roughly a third of those were patients in the U.S.

DePuy ASR Hip Implant Complications

The DePuy ASR hip implant is a metal-on-metal device made of chromium and cobalt, and consists of a cup that’s implanted into the hip with a ball joint that connects to the leg. According to a New York Times report published in March 2010, metal-on-metal hip implants have been used in about one-third of the approximately 250,000 hip replacements performed annually in this country. However, many of the nation’s leading orthopedic surgeons have reduced or stopped use of these devices because of concerns that they can cause severe tissue and bone damage.

It is believed that many of the complications linked to the DePuy ASR XL Acetabular hip implant are caused by wearing of the metal components, which can allow metal shavings to make their way into patients’ bloodstreams, leading to tissue breakdown, bone loss, and even the formation of non-cancerous tumors. The shedding of metal shavings can cause cobalt poisoning, a disorder that, if left untreated, can put patients at risk of tinnitus (ringing in the ears), vertigo, deafness, blindness, optic nerve atrophy, convulsions, headaches, peripheral neuropathy, cardiomyopathy, and hypothyroidism. Even patients who are not experiencing issues with their DePuy ASR hip implant may still be at risk for future complications. DePuy ASR hip implant patients have been advised to have their blood cobalt level tested, and such individuals may require medical monitoring for years to come.

Osteolysis bone loss disease

1. Osteolysis involves wear particles (worn off the contact surface of the artificial ball and socket joint). As the body attempts to clean up these wear particles (typically consisting of plastic or metal) it triggers an autoimmune reaction which causes resorption of living bone tissue. Osteolysis has been reported to occur as early as 12 months after implantation and is usually progressive. This may require a revision surgery (replacement of the prosthesis).

2. Aseptic loosening of a hip implant. Note the radiolucencies next to the implant, a result of osteolytic bone loss.

Study: 2nd-Gen Metal Hip Implants Tied to Adverse Reactions

Jan 23, 2014
A recent study reveals that second-generation metal-on-metal hip implants are tied to adverse reactions. The second-generation study found that most—two-thirds—of the cementless metal-on-metal revision surgeries conducted involved devices that were positioned out of the so-called “safe zone,” according to Helio. The hip devices revealed signs of wear and some patients also reported adverse reaction to metal debris as long as 15 years during the study’s follow-up,...

Recall Alert Over Johnson & Johnson's DePuy ASR Metal-on-Metal Hip Device Implemented in India

Dec 13, 2013
The DePuy Orthopaedic metal-on-metal hip replacement ASR device has been put on a so-called “recall alert” in India by that country’s health ministry after worldwide reports of metallosis (metal poisoning) in patients and premature and excessively high failure rates were received. The high failure rates often point to the need for revision surgery. Revision surgery involves removing and replacing a defective or failed device and replacing that device with a different device....

Patients Largely Unaware of Metal-on-Metal Implant Dangers

Dec 11, 2013
Despite its global recall in 2010, many patients remain unaware of the alleged dangers associated with the ASR metal-on-metal hip implant device manufactured by DePuy Orthopaedics, a unit of the global health care giant, Johnson & Johnson. In fact, less than 10 percent of some 4,500 patients in India have contacted Johnson & Johnson’s redressal agency, according to The Times of India. Because of this, India’s Food and Drug Administration commissioner, Mahesh Zagade, has...

Judge Denies DePuy's Appeal Attempt over ASR Verdict

May 28, 2013
A judge in California denied DePuy Orthopaedics’ effort to get a new trial to replace an earlier one that it lost in which the jury awarded $8.3 million to the plaintiff and found that the medical device maker had defectively designed its ASR XL metal-on-metal hip implant. The judge determined that the plaintiff in that case had presented enough evidence to show that DePuy, a subsidiary of Johnson & Johnson, had defectively designed the since-recalled ASR XL hip implant, according to...

Johnson & Johnson's DePuy Unit to Stop Selling Metal Hip Devices

May 17, 2013
In an announcement, health care giant Johnson & Johnson subsidiary DePuy Orthopaedics Inc. has announced it plans to stop selling some of its metal-on-metal hip devices. The move follows the filing of nearly 11,000 lawsuits over the company’s now-recalled DePuy ASR metal hip implant device. DePuy will discontinue its Ultamet metal-on-metal and its Complete ceramic-on-metal implants, citing low use, competing goods, and proposed changes by federal health regulators, according to a...
