Abstract
An adjustable button/loop device for securing biologic material in bone, such as for ACL reconstruction. The device has a pair of button/loop constructs, each including a flexible, adjustable loop integrated with a fixation device (for example, a wedge). Biologic material (for example, soft tissue, graft, ligament or tendon) is secured to the two fixation devices, and the construct is inserted into a pair of bone sockets/tunnels, such as into a tunnel in the tibia and a socket in the femur. The biologic material is secured within the bone by passing the buttons though respective bone sockets/tunnels, flipping and seating the buttons outside the bone, and then adjusting the lengths of the flexible adjustable loops passing through the buttons and the respective fixation devices, with the graft extending between the fixation devices thereby appropriately secured in the bone.
