Additional Manufacturer Narrative
This report is being submitted pursuant to the provisions of 21 cfr, part 803.This report may be based on information which has not been investigated or verified prior to the required reporting date.This report does not reflect a conclusion by depuy synthes, or its employees that the report constitutes an admission that the product, depuy synthes, or its employees caused or contributed to the potential event described in this report.If information is obtained that was not available for the initial report, a follow-up report will be filed as appropriate.H11: additional narrative: the actual device was evaluated.The device log files were reviewed for this event, and the investigation found that the complaint of inaccurate cuts could be confirmed since the pointer tool was used to verify resection planes.The investigation found that there was approximately -16.3 mm inaccuracy in the tibial cut.The investigation found that in the log file analyzed, significant array movement occurred during multiple steps before beginning of femur or tibia cuts.As array movement may have occurred prior to any femur or tibia cuts, there is a potential risk of inaccurate bone resections.When bone array moves, the accuracy of the system compromised, and this could lead to inaccurate cuts.There are no defects found with the system or software.The software was performing as intended.The investigation found that the most probable root cause of the reported issue is sub-optimal leg positioning and leg/robot movement in combination with potential array movement and sub-optimal anterior cortex line acquisition.The root cause for those issues could not be determined.
