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 joint reconstruction, or its employees that the report constitutes an admission that the product, depuy synthes joint reconstruction, or its employees caused or contributed to the potential event described in this report.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.The actual device was returned for evaluation.During evaluation it was determined that the reported condition of saw stuttered could be confirmed.It was found that when the device was run, the blade tip appeared to oscillate up and down (out of plane) while the motor was driven.It is unknown when this failure occurred.Review of the device log files for this event determined that inaccurate cuts "continually" could not be confirmed but one case was confirmed as inaccurate possibly related to the saw.The most probable cause of the saw issue is loss of performance.(premature wear).No defects were found with the system or software.The overall assignable root cause was determined to be due to user/improper handling and component failure and premature wear.D10, concomitant medical devices and therapy dates, base station device, robotic assisted satellite station device.(b)(6), 2023.
