The RetroButton XL’s unique button design facilitates greater button coverage over cortical bone, while minimizing the distance the button must travel past the cortex to flip. The “Z" shaped button covers 20 mm of bone with only 18 mm of overall length. This facilitates flipping and decreases the chance of catching soft tissue under the button. The short 11 mm loop allows the graft to be positioned directly under the button, maximizing soft tissue fill in short tunnels. Use the RetroButton XL when the femoral cortex is inadvertently damaged during drilling, for revision ACLR or when the femoral condyle is too small for a socket.
