The DePuy hip recall of the DePuy ASR hip cup comes years after the Johnson Law Firm’s hip implant lawyers’ investigation of the DePuy hip implant revealed published data and DePuy hip patients’ reports indicating that the DePuy hip device was defective and that the DePuy hip recall was necessary for the safety of the patients.
Patients with the Depuy ASR ACETABULAR CUP revisions should contact us about their rights. Depuy markets the ASR hip cup under the brand name ASR (Articular Surface Replacement). The DePuy ASR™ System is a large diameter, high performance metal-on-metal hip resurfacing device.
Numerous FDA reports of patients with loose DePuy ASR Acetabular Cups have been made by doctors after performing revision surgery.
The ASR hip cup revision reports also mention instances of loosening, pseudotumour and metallosis / (sic) metalosis. Surgeons have noted upon revsion that the DePuy ASR hip cup was “loose and easy to revise” and “the cup popped right out. There was no evidence of any bony ingrowth.” This is in spite of the surgeon’s prerevision observation that “The patient was revised to address complaint of extreme pain when weight bearing. X-rays looked good, and cup was in position.”
The Johnson Law Firm is filing individual DePuy Hip lawsuits for our clients who received the DePuy ASR hip replacement. We do not file our clients cases as part of any DePuy Hip class action.
The MHRA, an executive agency of the Department of Health has issued a Medical Device Alert for the Depuy ASR Acetabular Cup:
2,769 primary hip replacements were reported to the NJR for the DePuy ASRTM acetabular cups used with surface replacement heads between 01 April 2001 and 31 March 2010. The NJR prediction for expected revisions for this type of device was 80 but the actual reported revisions were 130.
3,155 primary hip replacements were reported to the NJR for the DePuy ASRTM acetabular cups used with extra large femoral heads between 01 April 2001 and 31 March 2010. The NJR prediction for expected revisions for this type of device was 85 but the actual reported revisions were 126.

The cause of the DePuy ASR Cup hip implant failures is under investigation. Abnormally high metal ions in surrounding tissue has been noted in some cases. This may cause an adverse reaction in the surrounding tissue and bone that prevents the cup from bonding. The DePuy ASR System’s release of the metal ions may be the result of wear on the bearing surface between the femur cap and the DePuy ASR acetabular cup.
The DePuy ASR hip recall finally ocurred in August 2010, years after the DePuy hip recall should have occurred. Studies showed years ago that the DePuy ASR was associated with high revision rates for hip replacement patients and that the Depuy hip was defective and dangerous to hip implant patients. The Depuy hip recall resulted only after hundreds of reports to the FDA of adverse events associated with the Depuy ASR hip and the reports of high metal ion levels being found in patients. The Depuy hip recall was announced in Australia some time ago. Thousands of DePuy hip implant patients will suffer painful hip revision surgeries and associated complications needlessly because the company continued to market the device even after it knew how dangerous the Depuy ASR was to patients.
DePuy ASR hip patients have been described as having ALVAL (aseptic lymphocyte dominated vasculitis associated lesion), adverse tissue reactions to metal particles and ions, and pseudotumour (a soft tissue mass that may be the result of a toxic reaction to an excess of particulate metal wear debris).

In March 2007 independent British surgeons published a report entitiled Incomplete seating of the liner with the Trident acetabular system, A CAUSE FOR CONCERN? Journal of Bone and Joint Surgery 2007 – British Volume, Vol 89-B, 291-295 by A. J. Langdown, et al. They found that it is difficult to place properly the Trident cup. The British surgeons suspected that the difficulty to place the Trident cup properly is caused by the fact “that the Trident shell deforms upon implantation, thereby preventing complete seating of the liner”. And they conclude “ We have identified a potential problem with the Trident ace-tabular shell when used in combination with its metal-backed ceramic liner”.
