Plain-English summary

Zimmer, Inc. is recalling 3,638 units of Natural-Knee N-K II Domed All-Poly Pat, sizes 0 and 1. The affected components are identified by item numbers 00591101128 and 00591101137. The recall covers distribution in the United States (including DC and specific states) and in Canada, Australia, India, Austria, Japan, Czech Republic, Seoul Korea, France, Venezuela, Germany, Luxembourg, Spain, and Switzerland.

The recall was initiated after a complaint was received regarding a discolored All Poly Tibia. Root cause analysis determined that the discoloration was the result of free radical oxidation. This oxidation process was advanced prematurely because the machined component was stored in a transparent container exposed to artificial light for six years prior to inert packaging and sterilization of the device.

Healthcare providers and patients should contact Zimmer, Inc. for further instructions regarding the affected components. The source text does not specify specific actions for consumers or report any illnesses or injuries associated with this recall.
