DePuy Hip Replacement: ASR Hip System
On August 24, 2010, Johnson and Johnson subsidiary DePuy Orthopaedics, a division of Johnson & Johnson, issued a voluntary recall of the DePuy ASR™ XL Acetabular System and DePuy ASR™ Hip Resurfacing System.
If you have one of these hips and have pain or weakness in the joint or are experiencing other symptoms, contact your doctor immediately. Those not experiencing any symptoms should still plan to consult with their doctors promptly, and on an ongoing basis annually.

Symptoms
While not all symptoms indicate a problem, you should take note of any unusual symptoms and all patients, regardless of symptoms, should follow up with regularly with their doctors. Even asymptomatic artificial hips may require revision:
- Pain
- Pain may be centralized at the joint or be felt in the leg, lower back, or elsewhere. Pain may be general and constant, or may occur specifically during movement (walking, sitting, standing, etc.).
- Unusual sounds
- Popping, clicking, grinding, or crunching sounds; unusual noises are often heard during movement of joint.
- Inflammation, Swelling
- Like pain, swelling may appear at the location of the implant or in the groin area surrounding the implant. Immediately after recovery, some inflammation is to be expected, but after recovery has occurred, unexplained swelling at the joint can be cause for concern.
- Weakness
- Weakness is often noted by patients who are having trouble walking or moving; some patients described having to lift their leg into position with their arms, having difficulty in starting a movement, or feeling the joint is not in place or is going out of place (sensation of dislocation).
- Other
- Other symptoms may include nausea, vomiting, fever, diarrhea, or headache. Increased levels of metal ions in the blood (from metal shed off the implant) can affect the heart, nerves, thyroid gland, and kidneys, causing such symptoms as chest pain, shortness of breath, numbness, fatigue, vertigo, memory loss, changes in vision or hearing, tinnitus, changes in urination, and other symptoms.
Issues & Injuries
Some of the issues and injuries associated with the ASR hip include:
- Loosening of the implant
- The metal components of the implanted device may loosen from the bone in which it's impanted.
- Loosening of the joint
- The cup and ball of the joint may loosen as a result of edge-loading or uneven wear, positioning, or for no immediately discernable cause.
- Joint dislocation
- Beyond simply loosening, the ball may become misaligned from or completely pulled out of the cup. Tendons may be ruptured.
- Bone fractures
- An increased fracture rate of the femur is considered one of the factors that held the ASR resurfacing device back from achieving FDA approval.
- Infection
- Infection may arise from a variety of causes.
- Metal debris injuries
- Metallosis, ALVAL, "metal poisoning," and a host of other names describe the injures caused by metal debris sloughed off these metal-on-metal hip implants.
"It is one of the biggest disasters in orthopaedic history"
When the ASR hip systems made by DePuy Orthopaedics were recalled in late summer 2010, it was viewed by many as too little, too late. Plagued by problems almost from the moment they hit the market, March 2011 numbers indicate that about half of these devices will fail within six years. A far cry from the 15 years hip replacements are expected to last.
That the ASR device reached the market at all is attributable in part to high medical device profits, the competition for valuable marketshare, and loopholes in the approval procedure. A lack of tracking mechanisms, the inability of at least certain regulators to act, and the power manufacturers wield over the fate of their products all contributed to the ASR remaining on the market as long as it did.
Unfortunately, it is now patients who are paying the price. Read more about the history of the DePuy ASR hip replacement system recall.
The heading quotation is from an investigative report for the British Medical Journal on the ASR. The reports opens: "It is one of the biggest disasters in orthopaedic history, according to one senior surgeon" (Cohen).
