It was reported that during an anterior cruciate ligament surgery the loop of the device did not lock.Per complaint reporter there was no harm for patient, operator or third party.The surgery was finished successfully with a new device with the same part number.It was not necessary to switch the surgical technique or do a second surgery.
Additional Manufacturer Narrative
Additional information: d9, g3, h3, h6.Complaint allegation is confirmed.Visual evaluation revealed that the tightrope system was damaged; the loops were tightened and shortened.Functional testing was not performed due to the damage to the device.The most likely cause can be attributed to user error, as excessive force on the shortening suture strands may break them and impair the ability to fully seat the implant.According to dfu-0147-eo - g.Precautions 1.Acl/pcl/btb/rt/abs tightrope only: excessive force on the shortening suture strands and/or tensioning the shortening suture strands not in line with the bone socket may break the strands and impair the ability to fully seat the implant.No additional force on the shortening suture strands is required when the graft/wedge construct reaches the desired position in the femoral socket, and the graft stability is verified by pulling distally on the graft.The most likely cause for the reported failure can be attributed to improper surgical technique and/or excessive force used during suture passing/tightening /tensioning.
