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...

BACKGROUND: Muscle atrophy and fatty infiltration in the rotator cuff muscles are often observed in patients with chronic rotator cuff tears. The recovery from these conditions has not been clarified. METHODS: Ninety-four patients were included in this study. The improvement in muscle atrophy and fatty infiltration in successfully repaired rotator cuff tears was evaluated by magnetic resonance imaging at 1 year and 2 years after surgery and was compared with muscle atrophy and fatty infiltration observed on magnetic resonance imaging at 2 weeks after surgery to discount any changes due to the medial retraction of the torn tendon...

INTRODUCTION: Rotator cuff pathology has been proposed to occur through intrinsic and extrinsic mechanisms. Hyperlipidemia has been proposed as a mechanism of intrinsic rotator cuff pathology. This prospective observational study evaluates serum and synovial lipid profiles in patients with and without rotator cuff tears to further define the relationship of cholesterol and rotator cuff pathology. METHODS: Patients were prospectively enrolled with intact rotator cuff (37 patients) and rotator cuff tear requiring a repair (40 patients) groups...

BACKGROUND: Postoperative rehabilitation after arthroscopic rotator cuff repair (ARCR) remains controversial and suffers from limited high-quality evidence. Therefore, appropriate use criteria must partially depend on expert opinion. HYPOTHESIS/PURPOSE: The purpose of the study was to determine and report on the standard and modified rehabilitation protocols after ARCR used by member orthopaedic surgeons of the American Orthopaedic Society for Sports Medicine (AOSSM) and the Arthroscopy Association of North America (AANA)...

The rotator cuff (RC) insertions according to most anatomical texts are described as being separate from one another. However, clear fusion of the RC tendon fibres exists with prior studies showing this interdigitation forming a common, continuous insertion onto and around the lesser and greater tubercles (LT and GT) of the humerus. Current surgical repair methods (especially arthroscopic techniques) rarely mention or consider these connections during repair and suture anchor implantation. The general principles of RC surgery remain a controversial subject, due to various available techniques, surgeon experience and preference, and the contradicting success rates...

BACKGROUND: As value becomes a larger component of heath care decision making, cost data can be evaluated for regional and physician variation. Value is determined by outcome divided by cost, and reducing cost increases value for patients. "Third-party spend" items are individual selections by surgeons used to perform procedures. Cost data for third-party spend items provide surgeons and hospitals with important information regarding care value, potential cost-saving opportunities, and the total cost of ownership of specific clinical decisions...

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)...

Diagnostic imaging plays an important role in the postoperative evaluation of the rotator cuff, as pain and disability may occur or persist after treatment. Postoperative imaging is therefore of paramount importance for clinicians before planning additional treatments. Multimodality imaging of the postoperative shoulder includes radiography, magnetic resonance (MR) imaging, MR arthrography, computed tomography (CT), CT arthrography, and ultrasound. Correct interpretation of imaging findings of the postoperative shoulder necessitates that the radiologist be familiar with the various treatment strategies, their possible complications and sources of failure, knowledge of normal and abnormal postoperative findings, and awareness of the advantages and weaknesses of the different imaging techniques...

#13
John G Skedros, Tanner R Henrie
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...

OBJECTIVE: While there has been increasing interest in minimally invasive surgery, the expenses incurred by patients undergoing this form of surgery have not been comprehensively studied. The authors compared the costs borne by patients undergoing arthroscopic rotator cuff repair with the standard mini-open repair at a tertiary hospital in an Asian population. PATIENTS AND METHODS: This was a retrospective cohort study. The authors studied the inpatient hospital bills of patients following rotator cuff tear repair between January 2010 and October 2014 via the hospital electronic medical records system...

BACKGROUND: In the past 16 years, the number of prescription opioids sold in the United States, as well as deaths from prescription opioids, has nearly quadrupled. However, the overall amount of pain reported by patients has not changed significantly. Specific information about opioid prescriptions in the perioperative period is lacking. Of the studies that have been published, investigators have shown that the majority of patients have unused postoperative opioid pills. Moreover, patients appear to lack information about disposal of unused opioid pills...

OBJECTIVES: All-suture anchors are increasingly used in rotator cuff repair procedures. Potential benefits include decreased bone damage. However, there is limited published evidence for the relative strength of fixation for all-suture anchors compared with traditional anchors. MATERIALS AND METHODS: A total of four commercially available all-suture anchors, the 'Y-Knot' (ConMed), Q-FIX (Smith & Nephew), ICONIX (Stryker) and JuggerKnot (Zimmer Biomet) and a traditional anchor control TWINFIX Ultra PK Suture Anchor (Smith & Nephew) were tested in cadaveric human humeral head rotator cuff repair models (n = 24)...

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...

BACKGROUND: The purpose of this study was to assess the effect of demineralized bone matrix (DBM) on rotator cuff tendon-bone healing. The hypothesis was that compared with a commercially available dermal matrix scaffold, DBM would result in a higher bone mineral density and regenerate a morphologically superior enthesis in a rat model of chronic rotator cuff degeneration. METHODS: Eighteen female Wistar rats underwent unilateral detachment of the supraspinatus tendon...

The use of biomaterial scaffolds has been an enormous field of research in tissue engineering, where the aim is to use graft materials for assisting the human body in recovering lost functions. Currently, there are many ways biomaterial scaffolds can be fabricated; however, many of these techniques involve the use of toxic organic solvents during the process. As biocompatibility is one of the mandatory requirements in designing a successful scaffold, there is an interest in fabricating scaffolds that are completely organic solvent-free...
