  • Publication number: 20220378409
    Abstract: Soft suture anchors are disclosed that can be formed into a pre-strung array with a common working suture. Each anchor includes the common working suture and a soft anchor member that is expandable when implanted. This allows first locking an individual anchor into a bone hole followed by tensioning the suture and independently locking the suture at the anchor. A first anchor is implanted through the tendon and the suture is locked. A second anchor is implanted a selected close distance from the first anchor, the working suture is tensioned between the first and second anchors, and the working suture is locked at the second anchor to create a single suture tensioned and locked stitch between the first and second anchor. This process is repeated for each anchor in the array.
