It was reported that, during navio tka procedure (while patient under anesthesia), upon handpiece registration the bur did not home.The surgeon did a handpiece test and it passed so he returned to the same case, but he had started and this time the registration was completed without issues.During the case, once they got to neutral leg collection, they got an error message saying the malleoli were collected incorrectly.The malleoli error message was after hip center.The surgeon hit the continue button to recollect the information once again and the same thing happened while trying to collect neutral leg alignment.At this point the surgeon ended the case and started a new one.The case was completed after a delay non greater than 30 min.Patient was not harmed.

The product, navio surgical system (us), npfs02000, sn(b)(6) used for treatment was not returned for evaluation, however log files were provided for review.Screenshots during the case show the "collection error-the malleoli points were collected in the wrong order".A relationship between the reported event and the device was confirmed.A functional evaluation could not be performed because the device was not returned.A review of manufacturing and service records indicate the device met all specifications upon release into distribution.A complaint history review for similar reported/confirmed complaints has identified prior events.The most likely cause of this event may be associated with the incorrect collection of the malleoli points and/or the femoral tracker pointing toward the ceiling during neutral position collection.Although no further containment or corrective action is recommended or required at this time, all complaints are monitored and trended through post market surveillance activities.If the product associated with this event is returned or provided at a future date, this evaluation will be reopened for investigation.
