Duracon augments tibial wedge implants - used in knee replacements
Hazard alert - potential for post-operative infection
Consumers and health professionals are advised that Stryker Australia, in consultation with the TGA, has issued a hazard alert for specific lots of Duracon augments tibial wedge implants.
Duracon augments tibial wedge implants are components used in knee replacement surgery (see image below). They replace bone or provide additional build-up to address certain problems, typically as part of revision surgery.
It has been identified that there is potential for Duracon augments tibial wedge implants to puncture the packaging before use. If this happens and is not detected in the operating room before implantation, the patient may receive a non-sterile implant and consequently suffer a post-operative infection (for example a fever).
There have been two overseas reports in which this device punctured the packaging before use, but in both cases the issue was recognised in the operating room and another implant was used.
The Instructions for Use (IFU) for these implants require that operating room staff inspect the package for damage before implantation and to not use the implant if any is identified. Due to this, it is unlikely that a patient would receive a non-sterile implant because of this issue. If a post-operative infection did occur, it would typically be in the period immediately following surgery.
Please note that there is potential for fever after any invasive surgery. Therefore, if a patient who receives Duracon augments tibial wedge implants experiences a post-operative infection, it does not necessarily mean they have received a non-sterile implant.
Information for consumers
The surgical procedures used for Duracon augments tibial wedge implants mean that, even if these components were used in knee replacement surgery, the likelihood of the above issue occurring is low.
The risk of developing a fever as a result of receiving a non-sterile implant is only present immediately after the surgery.
If you or someone you care for has recently had knee replacement surgery and you have any questions or concerns about this issue, please contact your surgeon or the hospital where the surgery was undertaken.
Information for all health professionals
If you are treating a patient who has recently had knee replacement surgery, reassure them that surgical procedures used for Duracon augments tibial wedge implants mean that the likelihood of the above issue occurring is low.
Advise them that the risk of developing an infection as a result of receiving a non-sterile implant is only presently immediately after surgery.
If they continue to have questions or concerns about this issue, refer them to their surgeon or the hospital where the surgery was undertaken.
