A device having an implantable body associated with at least two filaments or sutures and configured for use in soft tissue reconstructions is provided. One exemplary embodiment includes an implantable body 10 , an adjustable filament loop 42 for holding ligament grafts that is coupled to the body, and a shuttle suture 60 removably coupled to the implantable body and configured for shuttling the body through at least a portion of a bone tunnel. The loop can be defined by a self-locking knot, and one or more loop-adjusting limbs 52/54 can extend from the knot 46, with a portion of the limb(s) also extending into a hollow portion 66/68 of the shuttle suture. In some embodiments having two adjustable limbs, an intermediate portion of each limb can be the portions disposed in respective hollow portions of the shuttle suture. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.
