A complaint was received for a discolored All Poly Tibia. Root cause analysis found that the discoloration was the result of free radical oxidation. The oxidation process was advanced prematurely as a result of the machined component being stored in a transparent container exposed to artificial light for six years prior to inert packaging and sterilization of the device.
