H3, h6: the device, used in treatment, was not returned for evaluation and the reported event could not be confirmed.The clinical/medical investigation concluded that, per complaint details, a left insert revision was performed due to breakage of the bcs post approximately 12-13 years post tka in a 110kg patient.It was communicated that the requested clinical documentation was not available.Based on the information provided, the root cause of the reported event could not be fully assessed, and a definitive conclusion could not be established.Patient impact beyond the reported breakage and subsequent revision could not be determined, as the patient was reportedly "healthy".No further medical assessment could be rendered at this time.Should clinically relevant documentation become available in the future, this case may be re-opened/re-assessed.At this time, we have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.Some potential probable causes for this event could include but not limited to traumatic injury or surgical technique.Based on this investigation, the need for corrective action is not indicated.Without the return of the actual product involved, our investigation could not proceed.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.
