A worldwide recall of the DePuy ASR and ASR XL metal-on-metal (MOM) hip arthroplasties was announced on 27th August 2010 (96,000 patients worldwide and 7,500 in the UK).

The LIRC has been part of a five year project to independently inspect and store revised ASR/ASR XL MOM implants. We decontaminate, store and undertake detailed non-destructive inspection and metrology measurements of ASR devices. Handling of the implants and associated tissue by the LIRC is approved by the Human Tissue Authority.

The inspection reports produced in relation to these devices are sent to DePuy and also shared with respective surgeons, patients or legal representative of the patient upon request .

DePuy does not itself take possession of the ASR/ASR XL explants provided to the LIRC under the DePuy retrieval program. The explant remains the property of the patient at all times (even after delivery to the LIRC) and may be returned to the patient upon their request at any point.
