The Adjustable Loop Attachable Button System is a two-piece implant that facilitates implant passing through narrow bone tunnels, while allowing increased cortical fixation with the assembly of a large button over the cortical bone. The Loop Washer may be used for tibial fixation of the Graft for all-inside ACL reconstruction technique, or for fixation of the graft over small bone tunnels created during transtibial ACL reconstruction.
