Arthroscopic Subscapularis Tendon Repair Using the Lasso-Loop Technique Through Anterolateral Viewing Portal.

ABSTRACT: The subscapularis is the strongest muscle among the rotator cuff muscles, and it provides a coupled balanced force across the glenohumeral joint by resisting the infraspinatus in axial plane and the shearing force of deltoid in the coronal plane. It is important to repair subscapularis tears to maintain the coupled balanced force. Subscapularis tendon tears are difficult to diagnose and treat. Only a small portion of the subscapularis tendon is visualized during routine arthroscopy, as it is largely covered by the middle and inferior glenohumeral ligaments. Various repair techniques have been described in the literature. Here, we describe the anterolateral viewing portal for better visualization of subscapularis and our preferred technique, the lasso-loop technique, which provides better tissue grip and improved functional outcome.

Arthroscopic Single-Portal Subscapularis Tendon Repair.

Project description:Tears of the subscapularis tendon can be challenging to diagnose and treat. Because the subscapularis plays an important role in shoulder function, careful arthroscopic evaluation and treatment are necessary to restore function. Previous surgical techniques have ranged from full open repairs to complex arthroscopic procedures needing suture passer and/or retriever devices. We describe an arthroscopic surgical technique of subscapularis repair through a single anterior portal using only penetrating graspers. This approach can be used for partial upper-border subscapularis tears, as well as complete and retracted subscapularis tendon tears.

Single Portal Technique for Subscapularis Tendon Repair.

Project description:The fast and steady development of arthroscopy techniques in the last couple of decades led to a drastic increase of arthroscopic rotator cuff repairs over the open procedure. Supraspinatus tears are the most common of all, but the subscapularis tendon tear is a more common injury than expected. Most of the time it presents as a partial tear or is associated with a subsequent rotator cuff tendon injury, especially the supraspinatus. Nowadays, the standard procedure to repair the subscapularis tendon is performed arthroscopically, even though a real superior result over the open repair it is yet to be reported. Ideally less operative time, less scarring, and postoperative pain would be the expected benefits, but no study has compared the long-term outcome of these 2 procedures yet. To maximize possible improvements, we would like to present an arthroscopic technique: a subscapularis tendon repair performed with the aid of an angled suture passer and using a single anterior working portal.

The High Resistance Loop (H-Loop) Technique for Arthroscopic Repair of Subscapularis.

Project description:The subscapularis tendon is more challenging and riskier to repair than the posterior upper rotator cuff. The knotless anchor suture in subscapularis repair simplified the repair process and had an excellent postoperative effect. We describe a new knotless anchor stitching method, the H-Loop technique. The simplicity and efficiency of the technique make it particularly suitable for small subscapular tendon tears.

Arthroscopic Subscapularis Repair Using a Clever Hook and Lasso Loop Technique in the Beach Chair Position: A Simple and Reproducible Guide.

Project description:Addressing subscapularis tendon pathology has garnered increased attention during shoulder arthroscopy in attempt to adequately restore glenohumeral force couples. The appropriate rebalancing of force couples of the rotator cuff musculature by repairing subscapularis tendon tears in patients with large rotator cuff tears has been shown to improve functional outcomes while decreasing retear rates. However, subscapularis tendon tears may be particularly challenging to diagnose and present a significant degree of technical difficulty with the description of multiple arthroscopic and open surgical techniques. In this comprehensive guide, we put forth a simple, concise, and reproducible arthroscopic technique using a Clever Hook and Lasso Loop stitch technique for repairing both high-grade partial and full-thickness tears of the subscapularis tendon.

Arthroscopic Subscapularis Repair Through a Single Anterior Portal.

Project description:Arthroscopic subscapularis repair with knotted suture fixation typically requires use of both anterior and accessory superolateral portals with passage of suture through multiple anatomic spaces. The advent of knotless anchors has allowed for simplification of subscapularis repairs. In this report we describe a simple method of knotless arthroscopic subscapularis repair through a single anterior portal. The indication for a single-anterior portal knotless subscapularis repair is a complete tear of the upper one-third of the subscapularis. This approach can be used for isolated subscapularis repair or, in patients with multiple-tendon involvement, initial subscapularis repair to facilitate subsequent posterosuperior cuff repair.

Arthroscopic Knotless Repair of Complete Full-Thickness Tears of the Subscapularis Tendon Through a Single Portal.

Project description:Arthroscopic repair of subscapularis tendon tears has shown to be a reliable and reproducible technique and is now considered the gold standard method over open repair. However, most arthroscopic techniques use several working portals and the procedure can be technically challenging and time-consuming, especially when knot-tying is required and when multiple anchors are used. Recently, single-portal knotless techniques have been popularized for upper-third lesions (e.g. Lafosse type 1 or 2 tears). Here, we describe a technique of repairing complete tears of the subscapularis tendon (Lafosse type 3 and 4) using knotless suture anchors through a single portal. This technique is quick and allows a safe anatomic footprint repair to the lesser tuberosity.

Subscapularis Tendon Repair Using Suture Bridge Technique.

Project description:The subscapularis tendon plays an essential role in shoulder function. Although subscapularis tendon tears are less common than other rotator cuff tears, tears of the subscapularis tendon have increasingly been recognized with the advent of magnetic resonance imaging and arthroscopy. A suture bridge technique for the treatment of posterosuperior rotator cuff tears has provided the opportunity to improve the pressurized contact area and mean footprint pressure. However, suture bridge fixation of subscapularis tendon tears appears to be technically challenging. We describe an arthroscopic surgical technique for suture bridge repair of subscapularis tendon tears that obtains ideal cuff integrity and footprint restoration. Surgery using such a suture bridge technique is indicated for large tears, such as tears involving the entire first facet or more, tears with a disrupted lateral sling, and combined medium to large supraspinatus/infraspinatus tears.

Arthroscopic recognition and repair of the torn subscapularis tendon.

Project description:Although the subscapularis has historically received less attention than posterosuperior rotator cuff tears, repair of a torn subscapularis tendon is critically important to restoring anatomy and achieving the best functional outcome possible. Arthroscopic repair begins with proper recognition of the tear. A systematic approach can then be used to arthroscopically repair all types of subscapularis tendon tears, from partial tears to full-thickness tears, as well as those which are retracted and have adhesions medially. Subscapularis footprint restoration can be accomplished with a variety of repair techniques that must be matched to the extent of the tear and mobility of the tendon.

Double-Row Arthroscopic Subscapularis Repair: A Surgical Technique.

Project description:The subscapularis is the strongest rotator cuff muscle in the shoulder. Until recently, most surgical repairs were performed through an open approach. Furthermore, the reporting of arthroscopic repair techniques and outcomes is fairly limited. This is likely due to the difficulty involved in all-arthroscopic repairs and the relative rarity of this injury compared with injuries of the other rotator cuff tendons. Arthroscopic subscapularis repair can be challenging, even for an expert surgeon, and attempting a double-row repair adds further complexity. Given these issues, this article provides techniques to allow for successful arthroscopic double-row subscapularis repair and avoid potential complications. The key features of an arthroscopic double-row repair include portal placement, surgical technique, and tips to avoid potential pitfalls, all of which are discussed.

Knotless Arthroscopic Repair of Subscapularis Tendon Tears Using Looped Suture.

Project description:Subscapularis tendon tears present a technical challenge because both diagnosis and arthroscopic treatment can be difficult. One difficulty is the limited visualization and working space of the anterior shoulder. Although most tears of the subscapularis are partial- or full-thickness tears of the upper third of the tendon, occasionally, larger or more retracted tears are encountered. Various techniques have been developed to treat a wide variety of tear patterns. We present a simple technique using a looped suture that remains easy to use in the limited working space of the anterior shoulder; can be easily modified to accommodate a broad spectrum of subscapularis pathology, from partial to full and retracted tears; and uses familiar viewing and working portals. This technique creates a single-row, knotless repair. Traction on the superior suture improves visualization and ease of passing more inferior sutures. Risks include unintentional over-tensioning of the repair and medialization of the femoral footprint, which can be avoided with appropriate exposure and arm positioning during repair. Postoperative care includes restriction of external rotation for 3 to 6 weeks and strengthening at 3 months.
