It was reported that during an acl revision (which involved removal of titanium interference screws from a previous surgery) and a meniscal root repair procedure, the surgeon prepared the btb allograft with #5 fiberwire and #2 fiberwire.The femoral socket was prepared through the medial portal with the over-the-top guide and 2.4 mm beath pin, followed by a 10 mm low profile reamer to a depth of 30 mm.The tibial tunnel was prepared with an acufex guide, 2.4 mm drill tip pin, and 10 mm cannulated drill.The graft was passed with a #2 fiberwire through the tibial tunnel and into the femoral socket.An 8 mm tap with disposable sheath and tunnel notcher was used on the femoral socket.An 8 x 23 mm biocomposite interference screw w/ disposable sheath (ar-1380bc, lot: 10051207, (b)(6)) was inserted and broke while the surgeon was inserting it.All fragments of this screw were removed and a 7 mm tap was used to re-tap the femoral socket.A second screw, a 7x23mm biocomposite interference screw w/ disposable sheath (ar-1370c, lot: 10192231, (b)(6)) was inserted and this screw broke as well as the surgeon was inserting it.All fragments of this screw were removed.At this point a different bio-composite screwdriver was opened and used.An 8mm tap was used to retap the femoral socket and a 7x23mm biocomposite interference screw w/ disposable sheath (ar-1370c, lot: 10185735, (b)(6)) was inserted what seemed to be successfully.An 8mm tap, followed by a 9 mm tap was used on the tibial tunnel.While the surgeon was inserting a 9x23 biocomposite interference screw w/ disposable sheath (ar-1390c, lot: 10152151, (b)(6)) into the tibial tunnel, the screw broke and cut the sutures from the graft.At this point, the surgeon deemed it necessary to open a new btb allograft and restart the entire procedure.While he was removing the 7x23mm biocomposite interference screw w/ disposable sheath (ar-1370c, lot: 10185735, (b)(6)) from the femoral socket, it was revealed the screw was broken.The procedure was completed with the new btb allograft and a 7x20 titanium interference screw in the femur and an 8x20 titanium interference screw in the tibia.No fragments from any of the screws were left in the patient and the case was completed successfully.Follow-up investigation: this was a revision of a procedure that took place on (b)(6) 2013 where two arthrex titanium interference screws (part# unknown, (b)(6)) were implanted.The following screws were explanted during the revision: ar-1370e lot #573367, qty 1 ((b)(6)); ar-1380t, lot #587116, qty 1 ((b)(6)); ar-13372-1, lot #m12403a958, qty 2 ((b)(6)); sales rep has confirmed with the surgeon, who stated: "the revision was being done because the original surgery from five years ago had failed and the acl was torn again".
