Superior Capsule Reconstruction: A Glimpse into the Future?

ABSTRACT: The recent study by Mihata et al., [10] "Five-year follow-up of arthroscopic superior capsule reconstruction for irreparable rotator cuff tears" (J Bone Joint Surg Am. 2019;101:1921-1930), was the first case series published examining long-term clinical and radiographic outcomes of superior capsule reconstruction (SCR) for irreparable rotator cuff tears. This article is a critical review of how the aforementioned study fits into a growing literature surrounding the use of SCR for irreparable rotator cuff tears and how these results may impact clinical and operative decision-making for this patient population. The series compares clinical and radiographic data taken pre-operatively with data taken at 1 year and 5 years post-operatively in a group of 30 patients who underwent SCR utilizing tensor fascia lata autograft. While the results of the study suggest that a healed SCR graft utilizing this specific technique successfully restored shoulder function and prevented progression of rotator cuff arthropathy, it is important to appreciate the limitations of this small, retrospective case series. Nonetheless, the study represents an important addition to the expanding literature surrounding this significant topic. In this report, we shed light on the current state of this novel operative technique and the ongoing controversies revolving around graft material and thickness.

Magnetic Resonance Imaging Findings After Superior Capsule Reconstruction.

Project description:PurposeTo evaluate graft properties on magnetic resonance imaging (MRI) after superior capsular reconstruction (SCR) to help improve our understanding of postoperative imaging.MethodsWe identified consecutive patients who underwent SCR by a single surgeon and who had postoperative MRIs available. MRIs were analyzed to look for common postoperative findings on imaging.ResultsTen consecutive patients with an average age of 58 years who underwent SCR by a single surgeon had postoperative MRIs on average 404 days from surgery. Eight patients had completely intact grafts on follow-up MRI. All intact grafts were similar with homogenous appearance on all coronal images. All patients displayed some trace fluid with mild heterogenous signal at the level of the glenoid, which could represent failure of the graft to completely incorporate at the level of the glenoid or could be normal in the postoperative setting since all eight intact grafts displayed this finding. None of the patients with intact grafts had bony edema noted on either the glenoid or humeral side. Four of 8 patients were noted to have trace bony edema at the level of the lateral acromion. One patient had complete disruption on the glenoid side. One patient had partially intact graft that revealed heterogenous appearance of graft.ConclusionsAn intact graft displays a more homogenous signal on consecutive postoperative MRI coronal images than disrupted grafts or partially intact grafts. This suggests that intact grafts have better clinical outcomes than a partially disrupted or completely disrupted graft. However, the finding of heterogenous signal/fluid at the glenoid graft interface in all intact grafts could not be explained in this study.Level of evidenceLevel IV, therapeutic case series.

Superior Capsule Reconstruction Technique Using an Acellular Dermal Allograft.

Project description:Chronic, massive, irreparable rotator cuff tears remain one of the most challenging pathologies in shoulder surgery to treat. Because of this, many treatment options exist for the management of chronic retracted rotator cuff tears. Superior capsule reconstruction is one option that provides the potential to restore and rebalance the force couples necessary for dynamic shoulder function. We describe an all-arthroscopic technique using an acellular dermal allograft for superior capsule reconstruction indicated for patients with a deficient superior rotator cuff. This technique provides an option for patients with an irreparable rotator cuff tear without compromising future treatment options. Although this is a relatively new and unproven method for treating chronic irreparable rotator cuff tears, our short-term results are promising. Nevertheless, larger studies with long-term follow-up are required to fully evaluate the success of this technique.

Arthroscopic Superior Capsule Reconstruction for Irreparable Rotator Cuff Tears.

Project description:Massive irreparable rotator cuff tears in young patients are a particular challenge for the orthopaedic surgeon. Surgical treatment options include debridement, partial rotator cuff repair, patch-augmented rotator cuff repair, bridging rotator cuff reconstruction with graft interposition, tendon transfer, and reverse total shoulder arthroplasty. Recently, reconstruction of the superior glenohumeral capsule using a fascia lata autograft has been suggested to reduce superior glenohumeral translation and restore superior stability. Promising clinical results have been reported in 1 case series of 23 patients, indicating that superior capsular reconstruction may be a promising tool to manage massive irreparable rotator cuff tears. This article describes our preferred technique for arthroscopic superior capsule reconstruction.

Technique for Double Row Superior Capsule Reconstruction with Dermal Allograft.

Project description:Superior capsular reconstruction (SCR) is increasingly being used as a procedure for addressing irreparable rotator cuff tears. The procedure was initially described for failed rotator cuff repairs where the retears are severely retracted and when grade 3-4 fatty infiltration and atrophy exist. The SCR procedure can also be considered for irreparable rotator cuff tears in patients that are either too young or too high demand to be appropriate candidates for arthroplasty. Early short and medium term follow up studies support SCR with favorable outcomes compared with other salvage procedures.

Arthroscopic Superior Capsule Reconstruction With Doubled Autologous Semitendinosus Tendon Graft.

Project description:Massive and irreparable rotator cuff tears remain a difficult condition to treat. Fatty infiltration of the muscles and excessive retraction of the tendons predispose to high failure rates of arthroscopic repair techniques. In recent years, studies on the superior capsule have shown that it plays a key role in reducing superior humeral head translation and restoring balance to the force couples required for dynamic shoulder function. Superior capsule reconstruction has become common in clinical practice. Several techniques with different types of grafts have been described, such as fascia lata autograft, dermal allograft patch, and long head of the biceps tendon autograft. More recently, an open technique with semitendinosus tendon autograft has been proposed. Our aim is to describe an all-arthroscopic technique for superior capsule reconstruction using a doubled semitendinosus tendon autograft in a box-shaped configuration. We believe that the technique can combine the advantages of other techniques, such as graft availability, low harvest-site morbidity, limited cost, and mechanical strength.

Arthroscopic Superior Capsule Reconstruction Using Three-Dimensional Preoperative Planning: Technique Description.

Project description:We describe a technique using a fascia lata autograft with 3-dimensional (3D) printing to reconstruct the rotator cuff. Prototyping constitutes the construction of physical prototypes with high complexity after virtual studies. Such models increase the knowledge of the characteristics and size of rotator cuff injuries, thus improving the accuracy of determining the correct size of the graft to be used in superior capsule reconstruction. We present a case of superior capsule reconstruction using 3D printing for enhancing the accuracy of fascia lata allograft size and tension determination; 3D reconstruction has never been described in the literature for rotator cuff injuries.

Arthroscopic Superior Capsule Reconstruction with a Doubled-Over (6 mm) Dermal Allograft.

Project description:Superior capsule reconstruction has gained popularity as a treatment option for massive rotator cuff tears. The initial graft described was a tensor fascia lata. In the United States, acellular dermal matrix or dermal allograft has gained popularity. The results from published reports have been promising, but graft tear on postoperative imaging has been reported in several studies. Strives are being made to reduce the graft tear rate. One such way is to increase the thickness of the graft. Biomechanical studies have shown that thicker and stiffer grafts perform better in restoring superior stability. We present a technique of doubling a commercially available 3 mm dermal allograft and making it into a 6 mm graft for superior capsule reconstruction.

Cable Graft: Simple Superior Capsule Reconstruction Technique for Irreparable Rotator Cuff Tear Using a Teflon Patch.

Project description:We describe a simple superior capsule reconstruction technique for irreparable rotator cuff tear using a Teflon patch. In this technique, a triple-folded Teflon patch, suture tape, and a strong suture penetrating through the graft are fixed to the glenoid and greater tuberosity using a suture anchor. This allows for reconstruction of the superior capsule while simultaneously playing a role as a spacer. This procedure's greatest advantage is its simplicity; it is easy to perform, has a short operative time, and avoids the need to collect autologous tissue. More time is saved, as suturing and tying are not required. We believe our study could aid orthopaedic surgeons in clinical decision-making when encountering irreparable rotator cuff repairs.

Surgical Technique for Superior Capsule Reconstruction With 6-mm Acellular Dermal Allograft and Knotless Glenoid Anchors.

Project description:Superior capsule reconstruction (SCR) creates a humeral head depressor in the setting of a massive, irreparable rotator cuff tear. Recently, a 6-mm-thick acellular dermal allograft (ACD) has been shown to be noninferior to the standard fascia lata autograft in recreating native shoulder biomechanics. This paper outlines a reproducible means by which to perform an arthroscopic SCR using a 6-mm ACD. A standard diagnostic arthroscopy first assesses the integrity of the subscapularis and infraspinatus tendons. The glenoid anchors are then placed. Accessory anterior and posterolateral portals are made as well as a lateral portal by which to shuttle the graft. Suture management is paramount. Ideally allograft preparation occurs on the back table simultaneously to maintain efficiency. Suture passage through premade holes in the graft, and when the sutures have passed through and been tensioned, the graft is shuttled into place and tied down with medial and lateral row anchors in SpeedBridge fashion. The thickness of ACD has been shown to influence the ability of the reconstructed superior capsule to perform its role as a humeral head depressor. This technique describes the use of a 6-mm-thick ACD to perform an arthroscopic SCR that minimizes both donor-site morbidity and operative time.
