Manufacturer Narrative

Product complaint # (b)(4).Investigation summary - a surgery was performed on the patient's knee and at the moment of wanting to implant the tibial insert (5x8), the doctor could not, since the implant came with a failure that made insertion impossible.The device associated with this report was returned to depuy synthes for evaluation.Examination of the returned sigma tibial insert was performed without destructive testing.The tibial tray was not returned.Review of the returned tibial insert revealed evidence of deformation/witness marks on one of the posterior ridges of the tibial insert plateau underside.The witness marks are consistent with unsuccessful attempts of sliding the posterior ridge of the insert into the posterior undercut of the tray.Per the pfc sigma knee surgical technique, (sp2-007 115299-190528), the insert should be angled posteriorly and slid into position with the posterior undercut of the tray.The anterior margin of the of the insert is then tapped with a nylon mallet, deflecting the insert past the anterior lip of the tray until the insert is seated flush with the tray.The deformation observed on the insert suggests that the ridge of the insert was not fully interlocked with the undercut of the tray to allow for successful engagement during impaction.Soft tissue impingement and excess bone cement encroachment are potential contributing factors to consider and care should be take to clear the joint space of any obstruction before attempting to assemble the mating devices.In conclusion, no evidence of manufacturing or design related defects were observed that could have contributed to the unsuccessful attempts to assemble the insert.Dimensional and functional analysis could not be accurately performed due to the post-production damage of the interlocking features of the insert.Although the upon receipt burr was not confirmed the post-production damage observed would contribute to the sigma stab xlk ins 5 8mm not able to be used with a tibial tray.Based on the investigation findings, the potential cause is traced to unintended use error, and it has been determined that no corrective and/or preventative action is proposed.There is no indication that a design or manufacturing issue has caused the reported complaint condition.As part of depuy synthes quality process, all devices are manufactured, inspected, and released to approved specifications.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post-market safety surveillance activities.Device history lot - the product investigation found no evidence suspecting an error in the manufacturing or material that would be a contributing factor in the reported allegation(s).A manufacturing records evaluation (mre) was not performed.Corrected h3.
