      Abstract

      Rotator cuff tears remain one of the most common causes of shoulder pain and disability. Although many repair techniques like single-row, double-row, and transosseous equivalent repair have become popular, transosseous repair still remains the gold standard.
      Arthroscopic transosseous repair is a safe and affordable alternative to suture anchors. Considering this fact, a reusable instrumentation “ArthroCuff”, was developed by SpowerN Medical Equipment (Chennai, India) in collaboration with the National Hub for Healthcare Device Development, India. Arthrocuff system not only aids a robust transosseous rotator cuff repair, but it is also cost-effective. We present the video technique of Arthrocuff for rotator cuff repair.

      The arm is be suspended in traction in lateral posture. We proceed with the diagnostic arthroscopy by inspecting the glenohumeral joint through the posterolateral portal and, if necessary, performing a biceps tenotomy. With the arthroscope in the subacromial space, a subacromial clearing bursectomy is done. Subsequently, assessment of the cuff tear and footprint preparation is performed using standard techniques. An accessory lateral portal is made about 4 cm below the lateral end of acromion to pass the “ArthroCuff” jig, which is later needed to pass the loop transport shuttle sutures. This portal is slightly lower than normal lateral portal done routinely, so as to accommodate the free passage of the instrument under the acromion. Next a superior portal in line with the medial footprint of the rotator cuff is made to aid the passage of entry awl for the jig: the pilot hole. This is made using the 3.9-mm diameter straight awl. It is tapped up to the laser mark. This vertical hole additionally also allows for bone marrow to seep into the repair, which improves the biology and could aid healing. The ArthroCuff jig is introduced through the lateral portal. The jig facilitates a cannulated handle through which a 2.9-mm drill bit is used to prepare the transverse tunnel. The transverse tunnel, which is about 20 mm distal to the tip of the greater tuberosity, intersects the vertical drill hole, forming an L shape from the lateral border of humerus to the footprint area of the head. A shuttle suture is then introduced in the locking screw tip mechanism. The introducer with screw tip mechanism is introduced into the lateral aspect of transosseous jig and screwed onto the tip of the “ArthroCuff” jig. Subsequently, the jig is withdrawn along with the transosseous loop through the accessory lateral portal. Using the loop as a suture shuttle, the surgeon passes two no. 2 FiberWires into each tunnel. Using a retrograde suture passer, the surgeon passes the sutures through the rotator cuff as medial as possible, and standard arthroscopic sliding knots are used. Various suture configurations like simple, mattress, or transosseous equivalent can be used in this system, s necessary according to what the scenario is. In our system, the knots fall over the lateral cortex and close to the entry point of the transverse tunnel. This confers the advantage of a knotless system, and the tangential pull vector provides a large area of cuff compression over the footprint.

      Introduction

      Arthroscopic rotator cuff repair provides multiple advantages over open repair, like inspection of glenohumeral joint for pathologies, deltoid preservation, and early functional recovery.

      Anchors and disposable systems place a significant financial burden to the patients in cost-conscious countries. Therefore, we developed a reusable system for arthroscopic transosseous cuff repair called "ArthroCuff" to overcome the cost issues. This system confers the mechanical and biological advantages of the open transosseous repair system while retaining the benefit of being an arthroscopic procedure.
      We report the video technique of arthroscopic cuff repair using this system here (Video 1).

      Surgical Technique

      We prefer a lateral position with the affected arm suspended in traction. Next, we proceed with the diagnostic arthroscopy by doing a glenohumeral joint inspection through the posterolateral portal. At this stage, a biceps tenotomy, if indicated, is performed. Then, through a subacromial bursoscopy, rotator cuff tear pattern and mobility are assessed.
      A low lateral working portal is made about 4 cm below the lateral end of the acromion. This portal is slightly lower than the routine lateral portal in order to aid the free passage of the transosseous jig under the acromion (Fig 1). Subsequently, a superior portal is made in line with the medial footprint of the rotator cuff for creating the pilot hole, using the entry awl (Arthrocuff, SpowerN). The pilot hole serves as the vertical limb of the transosseous tunnel and is done using a 3.9-mm diameter straight awl tapped up to the laser mark (Fig 2). In addition to providing as an entry point for the jig, the pilot hole allows bone marrow to seep into the repair, enhancing biology and healing (Fig 3).

      The ArthroCuff jig (SpowerN Medical Equipment) is then introduced through the lateral portal, and the tip of the jig is manipulated to engage in the pilot hole (Fig 4). The jig has a cannulated handle through which a 2.9-mm drill bit is used to create the transverse tunnel. This intersects the vertical limb formed by the pilot hole, forming an L-shaped transosseous tunnel, from the lateral cortex of the proximal humerus to the footprint area on the head. The "ArthroCuff" jig is designed to create a bone bridge with the vertical tunnel of 22 mm and a transverse tunnel of 10 mm. This ensures maximal bone volume between the tunnels, which, in turn, minimizes suture cut-out and at the same time, it is not low enough to endanger the axillary nerve (Fig 5).

(C) The pilot hole is made close to the articular surface, and the jig has an inbuilt 10-mm horizontal offset and 22-mm vertical offset that helps in maintaining adequate bone bridge. (D) The pilot hole and the transverse drill meet to complete the tunnel.
      A shuttling loop loaded to the locking screw tip guide (SpowerN Medical Equipment) is introduced through the cannulated handle of the jig. Through the transverse tunnel, the guide with the shuttling mechanism encounters the Arthrocuff jig.(Fig 6) The screw locks to the tip of the jig and disengages from the guide. As the guide is removed, the screw and shuttle loop remains locked to the jig’s tip (Fig 7). Subsequently, the jig is withdrawn from the pilot hole, and the shuttling process is completed. Two FiberWires are shuttled through the transosseous tunnel using the shuttle loop (Fig 8).

      Using a retrograde suture passer, standard rotator cuff repair is completed using sliding knots. The above steps can be repeated in large tears to create another tunnel 1 cm apart in the footprint. Again, various suture configurations like simple, mattress, H-type or Xbox technique can be incorporated. In the ArthroCuff system, the knots fall over the lateral cortex and close to the entry point of the transverse tunnel (Fig 9), thus providing better footprint coverage, increased bone tendon surface contact, and a tangential compression vector perpendicular to the rotator cuff (Table 1).

      The initial fixation strength is mainly due to the tangential compression force in a tunnel repair technique, leading to a superior tuberosity–tendon fixation and limited interface micromotions. This, in turn, provides better healing potential.

      The lateral portal in our technique for introducing the jig is 4 cm from the tip of the acromion along its anterior border. This is in consideration of the normal anatomical variations of the course of the axillary nerve, which is usually 6.1 ± 0.7 cm from the top anteriorly and 7 cm posteriorly

      and the space needed to manipulate the jig in the subacromial space. We did not have any axillary nerve injury in our series of patients who had surgeries using this technique.
      Cadaveric biomechanical studies by Behrens et al. have compared the initial fixation strength of the suture bridge rotator cuff repair construct to the traditional transosseous suture construct. They have showed similar results with both techniques with respect to load to failure, and cyclical testing.

      The design of our transosseous jig (vertical 22 mm, transverse 10 mm) allows for maximal lateral cortical purchase to prevent suture cut-out and inherently enables a wider bone bridge.
      The void created by the tunnel in the lateral cortex may be considered a stress riser, and some authors have used cortical augments to fill the void. However, studies have shown no benefit with cortical augments.

      Conclusion

      Shoulder arthroscopy has become quite an expensive procedure with the need to use multiple suture anchors. Since ArthroCuff is an autoclavable and reusable implant-less system, it provides significant cost efficiency compared to Suture anchors, without compromising the results.
