Manufacturer Narrative

Updated investigation.Visual examination for the returned product found evidence of being implanted.The articular surface is extremely worn and fractured/cracked.The femoral condyle is fractured and all pieces were not returned.There is cement seen on part of the femoral component, however as product information for the cement and information of the cement technique used was not provided a definitive statement cannot be made.There is a lack of bone ingrowth seen on the femoral component which could indicate loosening.Device was submitted for further analysis.Analysis determined the femoral condyle fractured due to fatigue.Eds semi-quantitative elemental analysis of the fracture showed that it was consistent with co-cr-mo alloy.Review of complaint history identified additional similar complaints for the reported items and no additional complaints for the reported part and lot combinations.Complaints are monitored through monthly complaint review in order to identify potential adverse trends.A definitive root cause cannot be determined.No corrective actions, preventive actions, or field actions resulted after investigation of this event.Implant fracture and poly wear were confirmed; however, it is unknown whether the implant fracture or loosening occurred first.The loosening has not been confirmed therefore this complaint cannot be confirmed.
