Arthrex TightRope® ABS (Attachable Button System)
The TightRope ABS (Attachable Button System) for GraftLink simplifies tibial implant passing and allows usage of a larger button on the tibial cortex, when desired. The ABS system also facilitates backup fixation of the GraftLink construct by tying off the whipstitch sutures or “closing the loop” of the GraftLink construct. Recent biomechanical studies have shown impressive strength with this construct for tibial fixation, traditionally the “weak link” in ACL reconstruction. Closing the loop with TightRope ABS averages over 1000N of fixation with minimal displacement.
