Additional information: d9, g3, h3, h6.One unpackaged ar-1588tn-20 tightrope®, batch 15441519, was received for investigation.Visual inspection of the returned device noted that the sutures were torn.Additionally, the button was not returned for evaluation.Functional testing was not performed due to the damaged component.The most likely cause of the reported failure is user error, attributed to excessive force during suture passing, tightening, or tensioning.Per dfu-0147-eo revision 4; g.Precautions: ¿acl/pcl/btb/rt/abs/cl/cls/pf/pfc 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 complaint allegation is confirmed.
