BACKGROUND: Due to the highly organized tissue and avascular nature of the rotator cuff, rotator cuff tears have limited ability to heal after the tendon is reinserted directly on the greater tubercle of the humerus. Consequently, retears are among the most common complications after rotator cuff repair. Augmentation of rotator cuff repairs with patches has been an active area of research in recent years to reduce retear rate. HYPOTHESIS: Graft augmentation with 3D collagen could prevent retears of the repaired tendon and improve tendon-bone healing in moderate to large rotator cuff tears...

BACKGROUND: Little is known about the influence of rotator cuff pathology on sleep. The purpose of this study was to determine which patient-reported factors correlate with sleep disturbance in patients with rotator cuff disease. METHODS: A nonrandomized, cross-sectional cohort study was performed to evaluate the effects of rotator cuff disease on sleep quality. Data collected at time zero (before any treatment) included the Single Assessment Numeric Evaluation rating, the American Shoulder and Elbow Surgeons score, the Pittsburgh Sleep Quality Index, patient demographics, and medical comorbidities...

PURPOSE: Little information is available regarding the healing capacity of in situ and completion repair for the treatment of partial thickness rotator cuff tears. The purpose of the study was to analyze the healing characteristics of both techniques. METHODS: Twenty-four adult Sprague-Dawley rats were operated. Partial thickness bursal side tears were created bilaterally at the supraspinatus tendons. Additional 6 rats were used as the sham group. The right shoulders were repaired in situ, and the left shoulders were repaired using the tear completion technique on the 10th day after detachment surgery...

BACKGROUND: In a progredient rotator cuff tear with tendon retraction, fatty infiltration and atrophy of rotator cuff muscles the humerus cannot be centered and stabilized sufficiently in the glenohumeral joint. This leads to rotator cuff defect arthropathy as an eccentric osteoarthritis with acetabularization and wear of the acromion, as well as of the glenoid. INDICATION: A painful pseudoparalysis of the shoulder indicates the implantation of a reversed total shoulder arthroplasty (rTSA) to reduce pain and restore active motion...

OBJECTIVE: Shoulder symptoms are common and imaging is being increasingly used to help with management. However, the relationship between imaging and symptoms remain unclear. This review aims to understand the relationship between imaging-detected pathologies, symptoms and their persistence. METHODS: A systematic review using Medline, EMBASE, Cochrane and grey literature was conducted to April 2017. The cross-sectional and longitudinal relationships between imaging-detected abnormalities and symptoms were analysed and associations qualitatively characterised by a best evidence synthesis based on study design, covariate adjustment and the Grade of Recommendations Assessment, Development and Evaluation (GRADE)...

BACKGROUND: Patients with partial-thickness rotator cuff tears (PTRCTs) can be treated nonoperatively and/or undergo operative treatment, but the ideal time for surgical intervention is unclear. PURPOSE: The purpose is to compare the results of immediate arthroscopic rotator cuff repair with repair after 6 months of nonoperative care of PTRCTs involving more than 50% of the tendon thickness. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2...

BACKGROUND: Studies have demonstrated radiographic findings of sclerosis and cortical irregularity at the greater tuberosity can suggest a rotator cuff tear. Plain radiographs are the most easily attainable first-line investigations in evaluating shoulder injuries. This study determines the effectiveness in predicting degenerate rotator cuff tears by detecting radiographic changes on shoulder x-rays. METHODS: Retrospective cross-sectional study with a consecutive series of patients conducted in Hinchingbrooke Hospital, Huntingdon, United Kingdom from January 2015 to June 2017...

Study Design: Case-control study. Purpose: The aim of the present study was to identify physical findings useful for differentiating between cervical spondylotic amyotrophy (CSA) and rotator cuff tears to prevent the misdiagnosis of CSA as a rotator cuff tear. Overview of Literature: CSA and rotator cuff tears are often confused among patients presenting with difficulty in shoulder elevation. Methods: Twenty-five patients with CSA and 27 with rotator cuff tears were enrolled...

The critical shoulder angle and lateral acromioplasty are areas of controversy that are being studied in association with rotator cuff tears both as potential pathogenic variables and as surgically modifiable variables that could improve clinical outcomes. Current clinical evidence regarding the effectiveness and potential benefit of lateral acromioplasty support the hypothesis that modification of the bony anatomy may influence the integrity of the rotator cuff.

Arthroscopic rotator cuff repair in the obese patient offers functional outcomes and rates of complications comparable to those seen in nonobese patients. Future prospective studies with better methodology, as well as including larger numbers of severely obese patients with a body mass index of 40 or greater, will help to further elucidate if obesity truly affects outcomes in rotator cuff repair. In the meantime, be sure to consider admission of your obese rotator cuff repair patients.

BACKGROUND: To introduce a (semi-)quantitative surgical score for the classification of rotator cuff tears. MATERIAL AND METHODS: A total of 146 consecutive patients underwent rotator cuff repair and were assessed using the previously defined Advanced Rotator Cuff Tear Score (ARoCuS) criteria: muscle tendon, size, tissue quality, pattern as well as mobilization of the tear. The data set was split into a training (125 patients) and a testing set (21 patients). The training data set fitted a nonlinear predictive model of the tear score based on the ARoCuS criteria, while the testing data served as control...

BACKGROUND: Although sports participation and heavy physical work can contribute to rotator cuff tears, many patients expect to return to these activities after surgery; however, irreparable rotator cuff tears can preclude this outcome. A new surgical treatment-arthroscopic superior capsule reconstruction (SCR)-restores shoulder stability and muscle balance in patients with irreparable rotator cuff tears; consequently, it improves shoulder function and relieves pain. PURPOSE: To evaluate the rates of return to sports and physical work among patients treated with arthroscopic SCR...

A well-functioning rotator cuff is necessary for successful anatomic total shoulder arthroplasty (TSA). This study evaluated patients who underwent concomitant TSA and rotator cuff repair (RCR) for functional outcomes, revision rates, and predictors of poor results. Retrospective chart review was conducted to identify patients who underwent TSA and RCR. Demographic data, rotator cuff tear and RCR characteristics, range of motion, and radiographs were recorded. Minimum 2-year functional outcomes were obtained...

A survey of 67 experienced orthopedic surgeons indicated that precise portal placement was the most important skill in arthroscopic surgery. However, none of the currently available virtual reality simulators include simulation / training in portal placement, including haptic feedback of the necessary puncture force. This study aimed to: (1) measure the in vivo force and stiffness during a portal placement procedure in an actual operating room and (2) implement active haptic simulation of a portal placement procedure using the measured in vivo data...
