Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional and/or corrected information.The following sections were updated/corrected: h6.Mdr section codes updated/corrected: b, c, d, e, g.The revision reported was likely the result of a combination of prosthesis wear and femoral loosening.Additional reasons for the reported revision may be tibial loosening and inclusion of the polyethylene in the packaging recall.However, the reported tibial loosening could not be confirmed from the provided information.The prosthesis wear was likely due to excessive loading of the femoral component on the anterior portion of the tibial insert and third body wear.The loosening and osteolysis were likely the result of an insufficient bond between the implants and the bones and patient-related conditions.Potential contributions of user and patient-related considerations to the event could not be assessed as the devices were not available for evaluation.If any further information is obtained that would change or alter any information provided, a supplemental report will be filed accordingly.
