Manufacturer Narrative

(b)(4).This follow-up report is being submitted to relay additional information.The visual investigation confirmed the reported event.The cement mantle was found to be uneven but well attached to the tibial and femoral components, covering most of the non - articulating surface and slightly overhanging from the cement pocket.There is little evidence of bone integration on tibial tray and the femoral component.There are light scratches on the articulating surface of the femoral component.Deep scratches are visible on the articulating surfaces of the tibial tray, the surface damage could have appeared during implant removal.Considering that the implant was in use for over 12 years the polyethylene bearing is in overall good condition.Some pitting and light starches are observed on the bearing surface, this indicates that there might have been some third bodies present in the joint space, however this cannot be confirmed without radiographic images.The root cause of the reported event could not be determined from the information provided in the complaint.Device history record (dhr) was reviewed and no discrepancies were found.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
