Platelet-rich plasma (PRP) is a clinically relevant source of growth factors used commonly by surgeons. The clinical efficacy of PRP use as reported in the literature is widely variable which is likely attributed to poorly defined retention time of PRP at the repair site. To overcome this limitation, branched poly(ester urea) (PEU) nanofibers were used to adsorb and retain PRP at the implant site in an acute rotator-cuff tear model in rats. The adsorption of PRP to branched-PEU was characterized using quartz crystal microbalance (QCM) and immuno-protein assay...

BACKGROUND: Surgical management of rotator cuff tears is controversial and complex, ranging from nonoperative management to reverse shoulder arthroplasty. PURPOSE: To systematically review and evaluate the outcomes of graft augmentation or interposition versus rotator cuff repair (RCR) alone and evaluate via meta-analysis whether the use of a graft leads to superior outcomes versus RCR alone. STUDY DESIGN: Systematic review and meta-analysis...

BACKGROUND: Intratendinous lesions of the rotator cuff of the shoulder are frequent and may be a distinct clinical entity. Nevertheless, there are only a few publications which deal specifically with this subject. This study analyses the existing literature for the arthroscopic reconstruction of the intratendinous lesion of the supraspinatus tendon, by means of a systematic review, and identifies relevant research questions for future studies. MATERIAL AND METHODS: In January 2017, a systematic review of the U...

Inflammation and extracellular matrix (ECM) disorganization following the rotator cuff tendon injuries (RCTI) delay the repair and healing process and the molecular mechanisms underlying RCTI pathology are largely unknown. Here, we examined the role of HMGB1 and NLRP3 inflammasome pathway in the inflammation and ECM disorganization in RCTI. This hypothesis was tested in a tenotomy-RCTI rat model by transecting the RC tendon from the humerus. H&E and pentachrome staining revealed significant changes in the morphology, architecture and ECM organization in RC tendon tissues following RCTI when compared with contralateral control...

Background: After rotator cuff repair, some patients have ongoing problems significant enough to warrant presentation to a clinic for reassessment. Purpose/Hypothesis: The purpose of this study was to determine whether this cohort of patients was more likely to have a healed rotator cuff. We hypothesized that patients who had an unscheduled postoperative visit were more likely to have a healed rotator cuff than those who did not have an unscheduled postoperative visit...

Economic pressure highlights the critical need for appropriate diagnosis and treatment of various shoulder pathologies since under-diagnosis and under-treatment can result in increased costs to society in the form of disability and lost production. On the other hand, aggressive over-treatment can further inflate already burgeoning health-care costs and potentially harm the patient. Therefore, it is crucial to distinguish the indications between operative and nonoperative management, especially in common shoulder pathologies such as rotator cuff tears, anterior shoulder instability, biceps tendinitis, lesions to the acromioclavicular joint, and proximal humeral fractures...

OBJECTIVE: Hydroxyapatite (HA) crystal calcifications in or around the joint can induce acute flares with severe pain. A previous pilot study suggested that the interleukin 1β (IL-1β) inhibitor anakinra was effective. The goal of this observational study was to confirm these results in a larger set of patients and to report on the long-term follow-up. METHODS: Flare was defined as acute pain for<10 days. Calcification in or around a joint (rotator cuff: 15/23 patients) was confirmed by conventional radiography and/or ultrasonography (US)...

BACKGROUND: Although conventional Bankart repair has been the accepted procedure for traumatic anterior glenohumeral instability, the humeral avulsion of the glenohumeral ligament or an elongation of the capsule remains challenging to decide the appropriate treatment. The anatomical knowledge regarding the whole capsule of glenohumeral joint is necessary to accurately treat for the capsular disorders. The aims of the current study were to investigate the anatomical features of capsular attachment and thickness in a whole capsule of glenohumeral joint...

Rotator cuff pathology is a common cause of shoulder pain in the athletic and general population. Partial-thickness rotator cuff tears (PTRCT) are commonly encountered and can be bursal-sided, articular-sided, or intratendinous. Various techniques exist for the repair of bursal-sided PTRCTs. The 2 main distinctions when addressing these lesions include tear completion versus preservation of the intact fibers, and single- versus double-row suture anchor fixation. We present our method for addressing bursal-sided PTRCTs using an in situ repair technique with double-row suture anchors...

An irreparable anterosuperior massive rotator cuff tear with an irreparable subscapularis tear is not common; however, once symptomatic, it would become a challenging situation. Tendon transfer is a choice and the pectoralis major is a commonly selected graft source. However, there are theoretical concerns over its use: high invasiveness and low reproducibility, different force vector from the subscapularis, unsuitability for the arthroscopic modification, and difficulty in conversion to the reverse shoulder arthroplasty due to adhesions and scar formation in the anterior shoulder...

We report outcomes of using GraftJacket to repair massive rotator-cuff-tears. Twenty patients with a mean age of 64.6y over 12-month duration were reviewed. Two patients had a single GraftJacket repair (group1), whilst 18 had the GraftJacket sheet doubled (group2). Pre and post oxford shoulder scores (OSS) and patient related outcome measures were evaluated. A statistically significant improvement of OSS was demonstrated in-group 2 from a mean of 22 to 45.5 (p < 0.00148) over a follow up of 18 months...

Introduction: There are numerous configurations of double row fixation for rotator cuff tears however, there remains to be a consensus on the best method. In this study, we evaluated three different double-row configurations, including a new method. Our primary question is whether the new anchor and technique compares in biomechanical strength to standard double row techniques. Methods: Eighteen prepared fresh frozen bovine infraspinatus tendons were randomized to one of three groups including the New Double Row Equivalent, Arthrex Speedbridge and a transosseous equivalent using standard Stabilynx anchors...

The purpose of this study was to compare clinical outcomes and retear rate between arthroscopic double row (DR) and suture bridge (SB) repair for rotator cuff tears. Postoperative Constant score and MRI findings were compared between 52 patients underwent DR repair and 63 patients underwent SB repair with medium tear of the supraspinatus. There was no significant difference in Constant score between the two groups. Postoperative MRI revealed that retear rate of SB group was significantly lower than DR group...

The goal of this study was to determine the disease specificity and responsiveness of the Western Ontario Rotator Cuff Index (WORC). Responsiveness, two cut-off points of the minimal important change, the area under the curve, standard error of measurement, the minimal detectable change and the standardized response mean were determined. Patients undergoing a rotator cuff repair need to improve more than 35 points to be considered clinical importantly improved. The WORC is disease specific and has a high responsiveness in patients undergoing rotator cuff repair and patients with disease of the rotator cuff without rotator cuff tears...

BACKGROUND: Rotator cuff repair decreases pain, improves range of motion, and increases strength. Whether these improvements translate to an improvement in a patient's activity level postoperatively remains unknown. The Shoulder Activity Level is a valid and reliable outcomes survey that can be used to measure a patient's shoulder-specific activity level. Currently, there are no studies that examine the effect of rotator cuff repair on shoulder activity level. METHODS: Preoperative patient-determined outcomes scores collected prospectively on patients undergoing rotator cuff repair were compared with postoperative scores at a minimum of 2 years...

BACKGROUND: Rotator cuff tears are the most common shoulder injury, and little is known about the underlying etiology of fatty infiltration after rotator cuff tear. Previous studies speculated that rotator cuff tears lead to neural injury due to tethering of the suprascapular nerve at the notch. This study aimed to evaluate fatty infiltration after suprascapular nerve injury and rotator cuff tears. METHODS: Ninety adult male Sprague-Dawley rats were used and were divided into four groups: sham, tendon transection only, suprascapular nerve ligation, and tendon transection plus suprascapular nerve ligation...
