H3, h6: the device was not returned for evaluation; therefore, a device analysis could not be performed.However, an engineering evaluation was performed and the segmentation was found to be within visionaire standards.Therefore, no root cause could be determined for the complaint.The clinical/medical investigation concluded that definitive contributing clinical factors could not be concluded based on the limited information provided; however, a user technique cannot be ruled out as a potential contributor.The patient impact includes the reported additional cuts to achieve the 11mm poly insert.Since no further complications or surgical delay was reported, no further patient impact is anticipated.A review of the production order did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of complaint history of the previous 12 months revealed similar events for the listed device, this failure mode will be monitored for future complaints for any necessary corrective actions.Visionaire devices are patient-matched instruments, therefore, no additional review was performed for the batch number.A review of the instructions for use documents for visionaire patient matched instrumentation revealed that if the patient matched cutting block does not perform as intended, use the standard smith & nephew instrumentation to complete the surgery.A review of the risk management file revealed this failure mode was previously identified.The anticipated risk level is still adequate.A historical review concluded that there are no prior actions related to this product and event.According to inspection drawings, part number, size, implant type, hand, recut type and sawblade thickness shall be verified.Also, part configuration shall be compared to print.At this time, we have no evidence to conclude that the product failed to meet any specifications at the time of manufacture.Factors that could contribute to the reported event include surgical technique used or user/procedural variance.Based on this investigation, the need for corrective action is not indicated.Should the device or additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.
