Abstract

Methods and devices for tissue fixation. A cortical button with a rib between two slotted openings. The rib increases the cortical button structural rigidity without increasing palpability. An adjustable loop construct with two discrete locking passages that provides manageable loop reduction and improved tissue coupling. The adjustable loop construct may be coupled to tissue via a passing construct. An assembly with a reduction bar, a button and an adjustable loop construct, the assembly provided assembled in a first configuration that disassembles to guide steps of tissue fixation. The reduction bar may be assembled to the reduction bar for reducing the adjustable loop construct.
