Event or Problem Description
It was reported that a patient was revised approximately eight and half month's post implantation due to loosening with bone erosion and necrosis.A patient underwent right total knee arthroplasty with unknown implants on an unknown date and was subsequently revised with a stage i unknown cement spacer on an unknown date due to mssa infection.A stage ii implantation with a rotating hinge construct was performed during which, there was no evidence of persistent infection.All existing hardware and spacers were removed.An rhk was placed without complications.The patient did well until presenting with possible reinfection and evidence of femorotibial implant malrotation, patellar erosion, and bone necrosis.The patient was taken to the operating room approximately eight and a half months later; however, the surgeon decided to abort the procedure and have the patient return when culture results were available.Three days later, the patient returned to surgery for a full revision.During the revision the femoral component was clearly loose at the cement-bone interface.Extensive bone loss and defects were noted in the femoral, tibial, and patellar regions.A tibial tubercle osteotomy was performed to remove the tibial components and was secure with wires.Upon revision of tibial and femoral components with implantation of a patellar component, good tracking and stability was achieved.Attempts to obtain additional information have been made; however, no more information is available.
Additional Manufacturer Narrative
This follow-up is being submitted to relay additional information.No product was returned, or pictures provided; therefore, visual and dimensional evaluations could not be performed.Medical records were provided and reviewed by a health care professional.Review of the available records identified the following: necrotic debris and fibrosis on arthrotomy with histology samples taken, no results provided, femoral loosening, tibial and patella bone loss, tibial tubercle osteotomy (tto) fashioned / secured with 4 charnley wires.Device history record (dhr) was reviewed for deviations and/ or anomalies with no related deviations / anomalies identified.A definitive root cause cannot be determined for loosening of the femur and associated femoral components.For the reported infection, the issue was determined to be unrelated to the implanted zimmer biomet devices.The complaint is confirmed via medical records.If any further information is received which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
