Zimmer has issued a voluntary recall for certain lots of articulating polyethylene knee implants. The affected lots are in the Gender Solutions Natural-Knee Flex, Natural-Knee, Natural-Knee II, MOST Options and Apollo Systems lines.

The recall is the result of free radical oxidation which produced discoloration in these specific implants. The oxidation process was advanced prematurely due to the machined component being stored in a transparent container exposed to artificial light for 6 years prior to inert packaging and sterilization of the device.
