Abstract
An assembly and method are provided for incorporation into suture anchor designs to facilitate the locking of a slidable working suture after it has been tensioned. The assembly can be utilized on multiple anchors in a pre-strung chain on a single working suture to create continuous, individually tensioned suture bridges between anchors in series, without knot tying. Further, the bridges are independently locked with selected tension for the particular application. An anchor body having at least one suture receiving passage therethrough is threaded with a working suture wherein the working suture flosses through the passage when tension is applied to the working suture. A locking cord extends through a second passage through the anchor body, the locking cord having a collapsible loop extending out the second passage and encircling a portion of the working suture, wherein collapsing the loop locks the working suture after tensioning.
