H3, h6: evaluation is not possible, as the unknown endobutton device will not be returned.The part and lot number have not been provided making an examination of the manufacturing records prohibitive, however a review of the risk management, labeling and instructions for use documentation was reviewed for this device family and found to contain statements and instructions in regards to the use of the device to avoid damage or non-functionality.A review of the complaint records was also performed for this device family, which confirmed additional complaints have been reported within the scope of the reported study.The investigation was limited to the information provided.This investigation could not draw any conclusions about the reported event with the limited clinical details provided.If additional clinical details become available in the future, the investigation will be reopened.This complaint was reported from the literature review.The study suggest that the superiority of the double bundle might in part be due to the anatomical placement of the femoral fixation obtained using the anteromedial portal for drilling, rather than drilling the femur using the transtibial route in the single bundle groups.During the studying it was reported that after the double bundle acl reconstruction, the endobutton migrated from the lateral femoral cortex which caused some pain with flexion after 20 to 22 months postoperatively and required the removal at 23 months.The patient outcome is unknown.No individual clinical information has been provided for inclusion in this medical investigation, without supporting clinical/medical documents, a thorough investigation cannot be performed.Should information become available this complaint can be re-assessed.
