The Reason for the ASR Hip System Recall
DePuy’s top priority is and always has been patient safety. With this priority in mind, we continually evaluate data on our products, including the ASR Hip System.
According to 2010 data from an independent national registry in the UK that tracks implant performance and outcomes, while most patients with the ASR Hip System had not required additional hip surgery, the rate of ASR patients who needed revision surgery was not in line with data previously reported in that registry. In a revision surgery, the existing hip implant is removed and is replaced with a new hip implant.
This 2010 UK data indicated that within five years of having an ASR resurfacing device implanted, approximately 12 percent of patients had revision surgery, and that within five years of having an ASR total hip replacement, approximately 13 percent of patients had revision surgery, which was not in line with data previously reported in that registry.
After reviewing this data, DePuy decided it was in the best interests of patients to voluntarily recall the ASR Hip System. The company acted quickly by voluntarily recalling the product in every country where it was sold.
The company monitors data about ASR from a variety of sources, including joint registries, published literature, company-sponsored clinical trials, internal complaints data and external clinical research reports. Currently, there is a range of data reported regarding ASR revision rates, and the company is examining why the revision rate for ASR is reported to be higher than for other metal-on-metal hips.

Anatomy of the Hip
In a natural hip, the thigh bone, known as the femur, is connected to the pelvis at the hip joint. The femur has a rounded end, called the femoral head. The femoral head fits like a ball into a concave surface on the pelvis, known as the acetabulum. For this reason, the hip joint is often called a ball and socket joint. The femoral head rotates within the acetabulum, which allows for motion. When osteoarthritis, injury or other conditions cause the hip joint to lose mobility and become painful, a hip replacement or hip resurfacing surgery may be performed.
The ASR Hip System
The ASR Hip System was one of many hip implants available from DePuy. The ASR Hip System is a one-piece cup and socket that was used either for total hip replacement or hip resurfacing.
ASR XL Total Hip Replacement
With an ASR XL total hip replacement, a one-piece metal component known as an acetabular cup is placed in the acetabulum. The femoral head is replaced with a metal ball which is connected to a metal stem placed inside the femur.
An ASR XL System includes two components:
1. A metal femoral head (or ball) connected to the stem; and
2. A one-piece metal cup that lines the acetabulum
DePuy ASR Hip Resurfacing System
With a DePuy ASR Hip Resurfacing System, a one-piece metal component known as an acetabular cup is placed in the acetabulum and a metal cap is placed over the femoral head.
The DePuy ASR Hip Resurfacing System includes two components:
1. A metal cap is placed over the natural femoral head; and
2. A one-piece metal cup lines the acetabulum

Determining If You Have an ASR
If you had hip surgery prior to July 2003, the hip you received is not subject to this recall. If you had hip surgery after July 2003, please contact your orthopaedic surgeon or the hospital where your surgery took place to determine whether you received an ASR Hip.
It may take time for the surgeon or hospital to locate this information for you. For privacy reasons, your orthopaedic surgeon or the hospital where your surgery took place may ask you to request this information in person.
If you do not have an ASR Hip:
The hip you received is not subject to this recall. Please speak to your orthopaedic surgeon about any questions you may have about your hip replacement.
If you do have an ASR Hip:
• Contact the DePuy ASR Help Line to initiate a claim with DePuy.
• Schedule an appointment with your surgeon.
If you received the ASR™ XL Acetabular System or DePuy ASR™ Hip Resurfacing System, your surgeon will be able to evaluate how your ASR Hip System is functioning. Additional testing and treatment may be necessary to evaluate your hip implant.
DePuy is committed to addressing reasonable and customary costs of testing and treatment for reasons related to the recall, including revision surgery, if necessary. DePuy will also address recall-related patient out-of-pocket expenses, such as lost wages and travel costs. ASR patients should contact the ASR Help Line at 1800 665 460 for assistance.
Learn more about the claims and reimbursements process on the "Reimbursement" tab.
It is important that you follow up with your surgeon, even if you are not experiencing symptoms, for evaluation of your hip implant. You should discuss with your surgeon how frequently you should return for an office visit if you are not experiencing symptoms.
In some cases, your surgeon may order additional blood testing or imaging to evaluate your hip. Your surgeon will determine the best care plan for you and discuss treatment solutions should they be needed. If you don’t know who performed your hip replacement surgery, ask your primary care physician or the hospital where the surgery took place.
Learn more about Testing on the "Testing" tab.
Symptoms & Causes
ASR patients who required revision surgery have reported a variety of symptoms before having the revision surgery, including pain, swelling and problems walking. These symptoms are not unusual immediately after hip replacement surgery. If the symptoms continue or come back, you should consult with your surgeon.
Symptoms such as pain, swelling or problems walking might be caused by:
The implant does not stay attached to the bone in the correct position.
The bone around the implant may have broken.
The two parts of the implant that move against each other are no longer aligned.
Diagnostic testing will help your surgeon evaluate your hip and determine future treatment recommendations, if necessary.
What to Expect
Your surgeon may use one or more of several tests to evaluate your ASR Hip System:
X-rays will allow your surgeon to evaluate how the ASR Hip System is positioned, if there is any damage to the bone, and/or if the ASR Hip System has remained attached to the bone. If the x-rays show problems with your ASR Hip System, your surgeon may recommend additional testing or surgery to replace your hip implant.
• Blood Tests
Your surgeon may order blood testing as part of your ASR Hip System evaluation. Your surgeon may recommend a second blood test to confirm the results of the initial blood test.
• MRI or Ultrasound
Your surgeon may want to do an MRI or ultrasound test of your ASR Hip System. Your surgeon may then recommend additional testing or surgery to replace your implant.
Learn about Claims & Reimbursements for Testing on the “Reimbursement” tab.
Your surgeon will need to evaluate how your ASR Hip System is functioning and make a decision on the best course of treatment for your specific needs.
Learn more about testing and evaluation on the "Testing" tab.
If Your ASR Hip Is Functioning Well
If you do not have any symptoms or test results that suggest you may need to have your implant replaced, then you should follow your surgeon’s recommendations for continued follow-up.
If Revision Surgery Is Necessary
If you need to have an additional surgery, your surgeon will select the appropriate implant system for you. The manufacturer and model of any replacement implant system is a choice that you and your doctor are best positioned to make. DePuy is committed to addressing reasonable and customary costs of testing and treatment for reasons related to the recall, including revision surgery if necessary.
