Reason/Issue Zimmer received a single complaint regarding discoloration of a Natural-Knee II All Poly Congruent Tibia. An investigation into the event found that the discoloration was caused by oxidation resulting from prolonged exposure to artificial light after being machined by a third party supplier and awaiting completion and sterile packaging at Zimmer’s manufacturing facility. It is estimated that the above issue affects less than 2% of Natural-Knee II systems.
