Implant Retrieval and Analysis Program


The Implant Retrieval and Analysis Program (IRAP) began collecting implants in 2005. Failed total hip and knee replacement components removed at revision surgery are collected and archived by the Orthopaedic Innovation Centre and held at the CJRG site for future assessment. These used devices which previously would have been headed to medical waste disposal sites for destruction are now kept in a repository to allow for future assessment. This powerful tool allows researchers to look for patterns of failure with multiple specimens rather than the traditional assessment of one explant at a time.

The implants in IRAP can be combined with the clinical database of the CJRG to provide more detail about the in vivo conditions which may have affected the ultimate failure of the joint replacement device. This information can be fed back to surgeons, government and implant manufactures to advise them about changes to devices and surgical technique to improve patient outcomes.
