Additional Manufacturer Narrative
The affected legion hk guided motion insert and legion hinge sleeve were not returned for evaluation.As the devices were not made available for investigation, the failure mode cannot be determined or confirmed.However, batch number was provided for both devices.Thus, a review of the manufacturing records for the listed batches did not reveal any deviation from the standard manufacturing processes.Our investigation including a review of the complaint history for the listed parts revealed no prior complaints for the listed failure mode.There is no information that would suggest the implanted devices failed to meet specifications.A clinical evaluation noted that the photos, in addition to the x-rays were reviewed but do not indicate the reason for the breakage.Without the requested clinical information or the explant, the root cause of the implant fracture cannot be determined.The future impact to the patient beyond the revision cannot be determined.No further clinical/medical assessment is warranted at this time.Without the return of the actual product involved, our investigation of this report is inconclusive.No further investigation is warranted for this complaint; however we will continue to monitor for future complaints and investigate as necessary.Should the device or additional information be received, the complaint will be reopened.
