The low-profile Roman bridge technique for knotless double-row repair of the rotator cuff

Abstract

With advances in arthroscopic surgery, many techniques have been developed to increase the tendon-bone contact area, reconstituting a more anatomic configuration of the rotator cuff footprint and providing a better environment for tendon healing. We present a low-profile arthroscopic rotator cuff repair technique which uses suture bridges to optimize rotator cuff tendon-footprint contact area and mean pressure. A 5.5 mm Bio-Corkscrew suture anchor (Arthrex, Naples, FL, USA), double-loaded with No. 2 FiberWire sutures (Arthrex, Naples, FL, USA), is placed in the anteromedial aspect of the footprint. Two suture limbs from a single suture are both passed through a single anterior point in the rotator cuff. One suture limb is retrieved from the cannula. The second suture limb is passed through a single posterior point in the rotator cuff producing two points of fixation in the tendon, with a tendon bridge between them. The same suture limb is retrieved through the lateral portal, and then inserted into the bone by means of a Pushlock (Arthrex, Naples, FL, USA), placed approximately 1.5-2 cm posterior to the first anchor. This second suture is passed again in the posterior aspect of the cuff. The limbs of the first suture are pulled to compress the tendon in the medial aspect of the footprint. The two free suture limbs are used to produce suture bridges over the tendon by means of a Pushlock (Arthrex, Naples, FL, USA), placed 1 cm distal to the lateral edge of the footprint relative to the medially placed suture anchors anterior to posterior. This technique allows us to perform a low-profile (single pulley-suture bridges) repair for knotless double-row repair of the rotator cuff.
