H3, h6.The navio surgical system india, part number rob00036, serial number (b)(6), used for treatment was not returned for evaluation.A relationship between the reported event and the device could not be established.The clinical/medical investigation concluded that the device did not perform as intended during the ¿femur cut stage¿ of the surgery, and the navio system was abandoned.Per the field report form, the surgery was concluded using manual procedure with a 0-30 minute surgical extension without patient injury due to the reported event.Patient impact beyond the reported 0-30 minute surgical delay, abandoning the navio¿ system and subsequent use of manual instrumentation to perform the procedure would not be anticipated as manual procedure/standardized instrumentation is an approved surgical technique and no patient harm was alleged due to the reported event.A complaint history review for similar reported/confirmed complaints has identified prior events.A review of manufacturing records indicate the device met all specifications upon release into distribution.If a navio surgical system failure occurs at any point during the surgical case, refer to the surgical technique guide for knee arthroplasty, recovery procedure guidelines tables for proper guidance regarding recovering to a fully manual procedure.A failure can consist of, but is not limited to, a system software crash, unrecoverable hardware failure, handpiece failure with no backup available, tracker array failure or loss of contact with bone that is unrecoverable, etc.The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still within the product risk profile.Although the reported problem was not confirmed through a visual or functional evaluation, factors contributing to the reported symptom may have been associated with a drill/handpiece issue.Based on the investigation, the need for a corrective action is not recommended or required at this time.Should any additional information be received the complaint will be reopened.The failure mode will continue to be closely monitored through complaint investigation and trended through post market surveillance activities.
