BACKGROUND: Rotator cuff tear is a common finding in patients with painful, poorly functioning shoulders. The surgical management of this disorder has improved greatly and can now be fully arthroscopic. PURPOSE: To evaluate clinical and radiological results of arthroscopic rotator cuff repair using 2 different techniques: single-row anchor fixation versus transosseous hardware-free suture repair. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1...

PURPOSE: To determine if reoperation rates are higher for patients who underwent isolated rotator cuff repair (RCR) than those who underwent RCR with concomitant biceps tenodesis using a large private-payer database. METHODS: A national insurance database was queried for patients who underwent arthroscopic RCR between the years 2007 and 2014 (PearlDiver, Warsaw, IN). The Current Procedural Terminology (CPT) 29,827 (arthroscopy, shoulder, surgical; with RCR) identified RCR patients who were subdivided into 3 groups-group 1: RCR without biceps tenodesis; group 2: RCR with concomitant arthroscopic biceps tenodesis (CPT 29827 and 29,828); group 3: RCR with concomitant open biceps tenodesis (CPT 29827 and 23,430)...

BACKGROUND: The purpose of this study was to evaluate the relationship of fatty infiltration in rotator cuff muscles and shoulder strength in rotator cuff tears and these changes during nonsurgical treatment. METHODS: Fifty-three shoulders from 47 patients (mean age: 69.9 years) diagnosed with rotator cuff tears by magnetic resonance imaging (MRI) were treated nonsurgically. The degrees of fatty infiltration in supraspinatus (SSP) and infraspinatus (ISP) muscles were graded by the modified Goutallier classification (grade 0-1, grade 2-3, or grade 4)...

Stem cell research arose from the need to explore new therapeutic possibilities for intractable and lethal diseases. Although musculoskeletal disorders are basically nonlethal, their high prevalence and relative ease of performing clinical trials have facilitated the clinical application of stem cells in this field. However, few reliable clinical studies have been published, despite the plethora of in vitro and preclinical studies in stem cell research for regenerative medicine in the musculoskeletal system...

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.

BACKGROUND: The New Zealand Rotator Cuff Registry is a multicentre, nationwide prospective study of rotator cuff repairs established in March 2009. METHODS: A total of 1383 rotator cuff repairs were included in this study, all with completed baseline Flex-SF scores, pain scores and standardized operative forms. RESULTS: Increasing tear size and tear retraction, over 4 cm, were associated with decreasing Flex-SF scores but not pain. Tear area (a composite of tear size and retraction) is increased with advancing age, male gender and a traumatic history but not with smoking...

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: The aim of the study was to compare the clinical outcomes of patients undergoing all-arthroscopic (AA) or mini-open (MO) rotator cuff repair. METHODS: The present study evaluated 50 patients who had undergone AA repair and 50 patients who had undergone MO repair with a minimum 1-year follow-up. Every patient was asked to complete the Disabilities of the Arm, Shoulder and Hand (DASH) and visual analog scale (VAS) questionnaires. Constant-Murley score (CMS) and active ranges, forward flexion and external rotation, were also evaluated and documented...

BACKGROUND: There have been numerous reports of clinical outcomes associated with tendon healing after repair that suggest a nonhealed tendon has a negative effect on postoperative clinical outcomes. However, to our knowledge, there has been no report on the relationship between tear size progression of nonhealed tendons and clinical outcomes. QUESTIONS/PURPOSES: (1) Do patients with healed arthroscopic rotator cuff repairs have better outcomes, less pain, and more strength than patients whose repair did not heal? (2) In patients with nonhealed rotator cuff tendons, does tear size progression (increase or decrease) affect outcomes, pain, and strength? (3) Is there continued improvement beyond 6 months in outcomes, pain, and strength; and how do the improvements differ based on whether the tear size has increased or decreased? METHODS: Between May 2008 and December 2012, 647 patients underwent arthroscopic rotator cuff repair for full-thickness tears at our institution...

BACKGROUND: There are more than 40 outcome scores for evaluating shoulder pain and function. Some studies have correlated the results obtained using different scales, but none has compared the results obtained by the University of California, Los Angeles (UCLA) and American Shoulder and Elbow Surgeons (ASES) scores. METHODS: We performed a retrospective study to evaluate patients who underwent arthroscopic rotator cuff repair with 2 years' follow-up. The patients were evaluated by the UCLA and ASES scores preoperatively and at 6, 12, and 24 months after surgery...

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...

INTRODUCTION: Rotator cuff tears are common diseases of the upper extremity. There are no recommendations to the surgeon on how to prepare the footprint to ensure optimal tendon-to-bone healing. However, biologic augmentation using stem cells and growth factors is considered to encourage the healing process of the tendon. The aim of the study was to investigate the biomechanical and histological outcome of different footprint preparations in rotator cuff repair. MATERIAL AND METHODS: One hundred and eighty-nine Sprague-Dawley rats were randomly assigned to either spongialization, radiofrequency ablation or an untreated control group...

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...

We propose a technique to repair delamination, which often occurs during rotator cuff repair surgery. We have reported that the infraspinatus occupies most of the greater tuberosity with the articular capsule attached to a very wide area, and that the superficial layer is mainly composed of the infraspinatus, and the deep layer is mainly composed of the articular capsule. To repair such delamination with consideration of the detailed anatomy, we developed the following repair method with independent repair of the superficial layer (infraspinatus) and the deep layer (articular capsule): (1) the deep layer is pulled laterally and joined to the medial margin of the greater tuberosity using 4 simple sutures from 2 anchors; (2) the paired limbs (same color) of 4 knots are passed over the posterior leaf of the superficial layer at intervals; (3) a push-in anchor loaded with 1 thread each of 4 knots is placed on the anterolateral corner of the greater tuberosity to pull the superficial layer anterolaterally; (4) another push-in anchor (remaining threads) is pushed on the posterior corner of the greater tuberosity...

INTRODUCTION: We conducted a study to elucidate the correlation between the anatomy of the shoulder joint with the development of rotator cuff tear (RCT) and glenohumeral osteoarthritis (GHOA) by using acromioglenoid angle (AGA). MATERIALS AND METHODS: The AGA is a new measured angle formed between the line from midglenoid to lateral end of the acromion with the line parallel to the glenoid surface. The AGA was measured in a group of 85 shoulders with RCT, 49 with GHOA and 103 non-RCT/GHOA control shoulders...
