Hazard alert - potential for implant failure due to poor fixation

26 February 2015

Consumers and health professionals are advised that Smith & Nephew Surgical, in consultation with the TGA, has issued a hazard alert for Genesis II Knee System - non-porous tibial baseplates model number 71420182 with batch number 14CT39993.

The Genesis II Knee System - non-porous tibial baseplate is a component used in total knee replacements.

It has been identified that the surfaces of the identified batch of baseplates do not meet the product's specifications. Specifically, part of the device has been found to have inadequate surface roughness. This could result in poor fixation and loosening of the baseplate, which may lead to the device failing and the need for revision surgery. However, an analysis conducted by the manufacturer has found that the health risk for patients who have an affected device is low.

Only 18 affected devices have been implanted in Australia between May and September 2014.

This issue was discovered during the manufacturer's quality assurance processes. As of 20 February 2015, no adverse events associated with this issue have been reported in Australia or overseas.
