#1
In-Bo Kim, Dong Wook Jung
BACKGROUND: Shoulder stiffness is a common complication after arthroscopic rotator cuff repair. However, there is no consensus on the treatment of stiffness after repair. Although one treatment option is an intra-articular steroid injection, it may negatively affect repair integrity, and there is a paucity of literature regarding the timing of intra-articular injections for stiffness after repair and its effect on repair integrity. PURPOSE: To compare repair integrity and clinical outcomes after an intra-articular steroid injection administered at 6 weeks and 12 weeks postoperatively for shoulder stiffness after arthroscopic rotator cuff repair...

BACKGROUND: Intra-synovial tendon injuries display poor healing, which often results in reduced functionality and pain. A lack of effective therapeutic options has led to experimental approaches to augment natural tendon repair with autologous mesenchymal stem cells (MSCs) although the effects of the intra-synovial environment on the distribution, engraftment and functionality of implanted MSCs is not known. This study utilised a novel sheep model which, although in an anatomically different location, more accurately mimics the mechanical and synovial environment of the human rotator cuff, to determine the effects of intra-synovial implantation of MSCs...

A 'terrible triad' of anterior shoulder dislocation, axillary nerve damage and rotator cuff tear has been previously described. However, we are unaware of any report of anterior shoulder dislocation, humeral fracture, axillary neuropathy and subsequent rotator cuff tear requiring surgery when the axillary neuropathy was deemed permanent. We report the case of a 20-year-old woman who fell in a motocross accident and had an anterior shoulder dislocation, humeral fracture and axillary neuropathy. The fracture was treated surgically with open reduction and internal fixation...

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...

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...

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...

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...

PURPOSE: Computed tomography osteoabsorptiometry (CTO) is a method to analyze the stress distribution in joints by measuring the subchondral bone density. The purpose of this study was to evaluate the bone mineralization changes of the glenoid in shoulders with rotator cuff tears by CTO and to evaluate whether rotator cuff tears are associated with stress changes in the glenoid. METHODS: In total, 32 patients, who were diagnosed with unilateral rotator cuff tears and underwent arthroscopic rotator cuff repair, were enrolled in this study...

Recently, attention has been given to recalcitrant lateral hip pain, also known as greater trochanteric pain syndrome. Although, historically, this has been attributed to greater trochanteric bursitis, the literature has shown that many patients will have a lesion of the gluteus medius and minimus tendons. Endoscopic hip abductor tendon repair has been shown to provide good outcomes with decreasing overall morbidity and is becoming more popular. However, failure rates have been reported to be as high as 35%, likely due to the poor tissue quality in this older population...

OBJECTIVE: The objective of this article is to provide a multimodality imaging review of the imaging features of the postoperative rotator cuff, including a discussion of the most common complications. CONCLUSION: Both MRI and ultrasound can be used to evaluate the repaired rotator cuff and potential complications. The appearance of the rotator cuff within the first 6 months after repair is heterogeneous and may be difficult to interpret but normalizes over time...

Despite the development in shoulder surgery, massive irreparable rotator cuff tears still remain challenging for orthopaedic surgeons. Many surgical methods are addressed to this kind of pathology, but each of them has its own limitations. We decided to fuse the ideas of superior capsular reconstruction, "GraftJacket" technique, and partial rotator cuff repair. In this way, the technique using the long head biceps tendon simultaneously as a vascularized bridge between rotator cuff remnants and greater tubercle and as a depressor for the humeral head was created...

Background: Historically, tendon-to-bone fixation has relied on knot tying. However, considerable variability exists in knot-tying strength among surgeons. Purpose/Hypothesis: The purpose of this study was to compare the biomechanical properties of knotted and knotless fixation and to evaluate variability among surgeons. The hypothesis was that knotless constructs would be stronger and have less variability as compared with knotted constructs. Study Design: Controlled laboratory study...
