Attune distal femoral cutting jig was incorrectly set up/engaged by the nurse.It would seem that the cutting block was not connected at the unlock sign and then turned to the usual 9mm level.It seems the nurse put the dial to 9mm first, then connected the cutting block.While it does not engage, it seems to hold enough to be fooled into believing it is adequately holding.The surgeon trusted that the jig was correctly set at 9mm as was indicated by the dial and set up and proceeded to make the distal cut.17mm was taken instead of 9mm.This led to intra operative correction using distal augments and a femoral stem with a revision system.Was surgery delayed due to the reported event? yes.If yes, number of minutes: 60 minutes.Action taken when event occurred? switched to a revision femoral system.Was procedure successfully completed? yes.Were fragments generated? no.If yes, were they removed easily without additional intervention? unknown.Was there a clinical outcome experienced by the patient (infection, inflammation, etc.)? yes.Was other medical intervention (e.G.X-rays, additional procedures, prescriptions, otc, revision) required: yes.If yes, describe: more complex femoral revision surgery was required.Is the patient part of a clinical study? no.(b)(4).Device property of: none.Device in possession of: none.(b)(4).Device property of: none.Device in possession of: none.I certify that all information that are known/available has been disclosed.If any new information will be made available, the additional information will be submitted through cst.True.
