BACKGROUND: No previous study has examined whether isolated subscapularis tendon repair in irreparable posterosuperior massive rotator tears involving the subscapularis tendon in relatively young patients without arthritis can yield satisfactory outcomes. HYPOTHESIS: We hypothesized that this procedure would produce favorable outcomes in patients who might otherwise be candidates for reverse arthroplasty. STUDY DESIGN: Case series; Level of evidence, 4...

BACKGROUND: The purpose of this study was to investigate clinical outcomes and structural integrity after arthroscopic repair of anterosuperior massive rotator cuff tears (RCTs) and to compare clinical outcomes between healed and retear groups. HYPOTHESIS: The authors hypothesized that although both groups would exhibit improved clinical outcomes compared with their preoperative status, the healed group would have better clinical outcomes than the retear group, and in the retear group, the subscapularis retear subgroup would have inferior outcomes compared with the intact subscapularis repair subgroup...

BACKGROUND: Numerous studies have shown preoperative fatty infiltration of rotator cuff muscles to be strongly negatively correlated with the successful repair of massive rotator cuff tears (RCTs). PURPOSE: To assess the association between factors identified on preoperative magnetic resonance imaging (MRI), especially infraspinatus fatty infiltration, and the reparability of massive RCTs. STUDY DESIGN: Case-control study; Level of evidence, 3...

BACKGROUND: Recurrence rate of rotator cuff tears is still high despite the improvements of surgical techniques, materials used and a better knowledge of the healing process of the rotator cuff tendons. Large to massive rotator cuff tears are particularly associated with a high failure rate, especially in elderly. Augmentation of rotator cuff repairs with extracellular matrix or synthetic patches has gained popularity in recent years with the aim of reducing failure. The aim of this study was to investigate the outcome of rotator cuff repairs augmented with denatured extracellular matrix in a series of patients who underwent arthroscopic rotator cuff repair for large to massive tears...

BACKGROUND: Rehabilitation and overuse of the shoulder after rotator cuff repair are a concern in patients with comorbid disability in other extremities. Improvement of outcomes can be hampered in this situation. This study was to describe the clinical outcomes of rotator cuff repair in patients with comorbid disability in other extremities. METHODS: In two tertiary institutions, 16 patients with comorbid disability (9 men and 7 women; mean age of 57.1 years [range, 45 to 71 years]; 14 dominant arms; mean follow-up of 18 months [range, 12 to 38 months]) underwent rotator cuff repair...

EDITORIAL
Joshua S Dines
Patches have been used in a variety of ways to improve outcomes after repair of large to massive rotator cuff tears. Some authors have advocated using these patch grafts as augmentation, whereas other authors have used them as bridging tissue from the rotator cuff to the tuberosity. A recent study reports a well-written systematic review on healing rates and outcomes of the 2 different graft indications, showing no significant differences in healing. I do think that, equally as important, this study highlights the lack of well-designed studies on the use of patches in rotator cuff surgery...

BACKGROUND: Instability is one of the major causes of failures in unconstrained anatomic total shoulder arthroplasty (TSA). This study reviewed the instabilities that may occur in an anatomic shoulder platform system to identify its potential predictors. We hypothesized that soft tissue deficiency was the main cause of instability and that the best treatment option would be conversion to a reverse shoulder arthroplasty (RSA). MATERIALS AND METHODS: Between 2003 and 2013, we reviewed 27 patients who experienced postoperative instability, and the overall incidence was 5...

INTRODUCTION: Massive rotator cuff tear repair results are variable. The main purpose of this study was to compare functional outcome between two procedures: open repair by autologous quadriceps-patella tendon patch, and arthroscopic suture. The study hypothesis was that there is no significant difference in results between the two techniques. MATERIAL AND METHODS: A retrospective study included all patients younger than 70 years operated on from 1995 to 2013 for massive rotator cuff tear...

BACKGROUND: The humerus shaft is one of the sites with the largest probability of developing pseudoarthrosis after fracture. We present the results of nine patients with atrophic pseudoarthrosis of humeral shaft treated with angular stability plate associated with allograft and platelet-rich plasma (PRP), after a first treatment with intramedullary nail to correct the fracture. MATERIAL AND METHODS: From January 2012 to December 2014, nine patients were treated for atrophic pseudoarthrosis (PSA) of humeral shaft treated previously using intramedullary nail; seven humeral diaphysis fractures were located in the middle-proximal third and two in the middle third...

BACKGROUND: Arthroscopic repair of large to massive rotator cuff tears commonly retear. To improve healing rates, a number of different approaches have been utilized, including the use of grafts, which may enhance the biomechanical and biologic aspects of the repair construct. However, the outcomes after the use of grafts are diverse. PURPOSE: To systematically review the literature for large to massive rotator cuff tears to determine whether the use of grafts generally provides superior tendon healing and clinical outcomes to the repairs without grafts...

BACKGROUND: Rotator cuff tears are a common cause of shoulder pain and often necessitate operative repair. Muscle atrophy, fibrosis, and fatty infiltration can develop after rotator cuff tears, which may compromise surgical outcomes. This study investigated the regenerative potential of 2 human adipose-derived progenitor cell lineages in a murine model of massive rotator cuff tears. METHODS: Ninety immunodeficient mice were used (15 groups of 6 mice). Mice were assigned to 1 of 3 surgical procedures: sham, supraspinatus and infraspinatus tendon transection (TT), or TT and denervation via suprascapular nerve transection (TT + DN)...

Massive irreparable rotator cuff tears can be reconstructed with latissimus dorsi tendon transfers (LDTT). Although uncommon, the natural length of the latissimus dorsi tendon (LDT) could be insufficient for transfer even after adequate soft tissue releases. Descriptions of cases where grafts were needed to lengthen the LDT are therefore rare. We located only two reports of the use of an acellular dermal matrix to increase effective tendon length in tendon transfers about the shoulder: (1) GraftJacket patch for a pectoralis major tendon reconstruction and (2) ArthroFlex® patch for LDTT...

We report a case of subcutaneous ganglion adjacent to the acromioclavicular joint with massive rotator cuff tear [1-7]. An 81-year-old woman presented with a ganglion adjacent to the acromioclavicular joint that had first been identified 9 months earlier. The ganglion had recurred after having been aspirated by her local physician, so she was referred to our hospital. The puncture fluid was yellowish, clear and viscous. Magnetic resonance imaging identified a massive rotator cuff tear with multi- lobular cystic lesions continuous to the acromioclavicular joint, presenting the "geyser sign"...

PURPOSE: The primary purpose of this study was to determine the effect of the preoperative position of the musculotendinous junction (MTJ) on rotator cuff healing after double-row arthroscopic rotator cuff repair. A secondary purpose was to evaluate how tendon length and MTJ position change when the rotator cuff heals. METHODS: Preoperative and postoperative magnetic resonance imaging (MRI) scans of 42 patients undergoing arthroscopic double-row rotator cuff repair were reviewed...

We have been performing arthroscopic superior capsular reconstruction (SCR) with acellular dermal allograft for almost 2 years. Our techniques are based on Mihata's original concept for SCR, in which he used fascia lata autograft. In this report, we describe our standard arthroscopic technique as well as 2 variations of a "zip-line" technique, which we have found particularly useful for large dermal allografts (grafts that are ≥40 mm in any dimension).

Excellent clinical results of arthroscopic repair of rotator cuff tears have been reported. However, retears after surgical repair of large and massive rotator cuff tears are one of the most common complications. We present single-row repair with graft augmentation of the fascia lata for large and massive rotator cuff tears to reduce tension at the tendon-bone repair site, and this technique may prevent retears of the repaired rotator cuff. A candidate for this technique is a patient who has a large or massive rotator cuff tear in which the torn edge cannot reach the footprint after mobilization of the torn rotator cuff...

BACKGROUND: Cellular remodeling in rotator cuff muscles following a massive rotator cuff tear is poorly understood. The aim of the current study was to provide histological evidence to elucidate the mode of muscle loss in advanced human rotator cuff disease and to assess tissue-level changes in relation to findings on noninvasive imaging. METHODS: Rotator cuff muscle biopsy samples were taken from the scapular fossae from 23 consecutive patients undergoing reverse total shoulder arthroplasty in order to evaluate muscle composition in severe rotator cuff disease...

BACKGROUND: Management of massive rotator cuff tears in shoulders without glenohumeral arthritis remains problematic for surgeons. Repairs of massive rotator cuff tears have failure rates of 20% to 94% at 1 to 2 years postoperatively as demonstrated with arthrography, ultrasound, and magnetic resonance imaging. Additionally, inconsistent outcomes have been reported with debridement alone of massive rotator cuff tears, and limitations have been seen with other current methods of operative intervention, including arthroplasty and tendon transfers...

Rotator cuff tear is one of the most common types of shoulder injuries, often resulting in pain and physical debilitation. Allogeneic tendon-derived decellularized matrices do not have appropriate pore size and porosity to facilitate cell infiltration, while commercially-available synthetic scaffolds are often inadequate at inducing tenogenic differentiation. The aim of this study is to develop an advanced 3D aligned collagen/silk scaffold (ACS) and investigate its efficacy in a rabbit massive rotator cuff tear model...
