Event or Problem Description
It was reported approximately 86 months after a left total knee replacement surgery; a male patient underwent a left knee revision procedure to address pain and symptoms of instability.A revision operative report was provided.Operative findings noted the patella component was well fixed, femoral component loose and de-bonded from the cement and the tibial well fixed.It was noted the polyethylene insert showed evidence of wear of the medial tibial tray.Infectious workup was performed; inflammatory markers were negative.The patient was revised to a competitor's construct.The patient was noted to be in stable condition following the procedure.No additional information is available.
Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional and/or corrected information.The reason for the revision reported cannot be confirmed from the information provided but may be the result of prosthesis wear, instability, and femoral loosening.The reported femoral loosening may have been a result of failure of the cement used to secure the femoral component to the femoral bone, which led to loosening at the cement-implant interface.Potential contributions of user and patient-related considerations to the event could not be assessed as the devices were not available for evaluation and images and radiographs were not provided.If any further information is obtained that would change or alter any information provided, a supplemental report will be filed accordingly.
