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.

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.

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.

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.

Partial Rotator Cuff Repair Provides Improved Patient-Reported Outcome Measures Following Superior Capsule Reconstruction (SCR).

Project description:PurposeTo evaluate the role of concomitant partial rotator cuff repair (RCR) (i.e., infraspinatus) on patient-reported clinical outcomes following superior capsule reconstruction (SCR).MethodsPostoperative recovery outcomes of SCR alone were compared with SCR with concomitant infraspinatus rotator cuff repair (SCR+RCR) at 3, 6, 12, and 24 months. Patients were included if they had an SCR surgery with or without a concomitant infraspinatus repair. Patients were excluded if they did not have a minimum of 6 months' follow-up or if a preoperative baseline questionnaire was not performed. Outcome measures included pain visual analog scale, American Shoulder and Elbow Surgeons (ASES) Shoulder Function, ASES Shoulder Index, and Single Assessment Numeric Evaluation (SANE) score.ResultsOverall, 180 patients were evaluated, including 163 patients who underwent SCR alone and 17 patients who underwent concomitant infraspinatus repair (SCR+RCR). There was no difference in demographic data including age, sex, and body mass index. The postoperative recovery curves demonstrated SCR alone and SCR+RCR both provide significantly improved pain and functional scores at 2 years postoperatively (P < .001). When we compared the 2 groups, SCR+RCR provided significantly improved ASES Index (87.6 vs 78.2, P = .048) and ASES Function (25.5 vs 21.7, P = .02). There was no statistically significant difference in SANE scores (75.5 vs 64.2, P = .07) at 24 months' follow-up.ConclusionsSCR provides modest improvements in pain and function at 2 years postoperatively in patients with irreparable rotator cuff tears. Patients who underwent SCR and concomitant infraspinatus repair demonstrated significantly improved ASES Index and ASES Function scores and statistically nonsignificant improvement in SANE scores at 24 months postoperatively when compared with SCR alone.Level of evidenceIII, retrospective cohort study.
