The RetroButton® is a fast way to obtain strong suture button fixation on cortical bone. The 12 mm or 15 mm long titanium buttons pass through a small cortical pin hole without overdrilling, which saves time and preserves bone. The simplified measuring technique also reduces steps and improves sizing accuracy. The continuous polyethylene loop, available in 10 lengths (15 - 60 mm), provides maximum strength and stiffness with a widened, atraumatic graft interface to protect graft integrity.The RetroButton Graft Prep Station attachment allows graft tensioning with the RetroButton in place and confirms proper loop length.
TheRetroButton® XL’s unique button design facilitates greater button coverage overcortical bone, while minimizing the distance the button must travel past thecortex to flip. The “Z” shaped button covers 20 mm of bone with only 18 mm ofoverall length. This facilitates flipping and decreases the chance of catchingsoft tissue under the button. The short 11 mm loop allows the graft to bepositioned directly under the button, maximizing soft tissue fill in shorttunnels. Use the RetroButton XL when the femoral cortex is inadvertentlydamaged during drilling, for revision ACLR or when the femoral condyle is toosmall for a socket.
