BACKGROUND The purposes of this study were to identify changes in tear dimensions, shoulder function, and glenohumeral kinematics when an asymptomatic rotator cuff tear becomes painful and to identify characteristics of individuals who develop pain compared with those who remain asymptomatic. METHODS A cohort of 195 subjects with an asymptomatic rotator cuff tear was prospectively monitored f...

Subscapularis tendon tears are a well-established cause of shoulder pain. The objective of the current study was to evaluate the associated shoulder pathology in patients with full-thickness subscapularis tendon tears using magnetic resonance imaging. Forty-seven magnetic resonance imaging studies taken between 2008 and 2009 with a diagnosis of full-thickness subscapularis tendon tears were rev...

Our aim was to determine the most repeatable three-dimensional measurement of glenoid orientation and to compare it between shoulders with intact and torn rotator cuffs. Our null hypothesis was that glenoid orientation in the scapulae of shoulders with a full-thickness tear of the rotator cuff was the same as that in shoulders with an intact rotator cuff. We studied 24 shoulders in cadavers, 12...

BACKGROUND Increased age, larger tear size, and more advanced fatty degeneration of the rotator cuff musculature have been correlated with poorer healing rates after rotator cuff repair. Platelets are an endogenous source of growth factors present during rotator cuff healing. HYPOTHESIS Augmentation of rotator cuff repairs with platelet-rich fibrin matrix (PRFM) may improve the biology of rot...

OBJECTIVE To compare the clinical outcomes following conservative treatment and arthroscopic repair in patients with a rotator cuff tear. METHODS In this retrospective study, patients aged >50 years with a symptomatic rotator cuff tear were reviewed. The rotator cuff tendons were evaluated using ultrasonography, shoulder magnetic resonance imaging or MR arthrography, and the patients with eit...

The purpose of this study was to investigate the characteristics of rotator cuff tears and the clinical outcome of rotator cuff repair in patients under 50 years of age. Sixty-eight patients (72 shoulders) aged < 50 years, who underwent repair of rotator cuff tears were evaluated. We analyzed the cause of injury, tear size, time from symptom onset to surgery, and rate that patients returned to ...

OBJECTIVE. The management of patients with signs and symptoms referable to the rotator cuff depends on the presence of cuff injury and the size of the tear. Treatment options include conservative nonsurgical management for patients with an intact or partially tom cuff, arthroscopic decompression of the coracoacromlal space for those not responding to nonsurgical management, and a range of surgi...

abstract   background: despite being the largest rotator cuff tendon of the shoulder, the function and clinical relevance of subscapularis pathology has been largely ignored in the literature. although many studies have focused on subscapularis tears recently, majority of them reported techniques for open repair. the advent of arthroscopy and arthroscopic repair techniques has opened new fronti...

Introduction Rotator cuff tears are a common cause of pain and disability. 2 With modern advances in arthroscopy and arthroscopic techniques, most rotator cuff tears can now be repaired arthroscopically, with several authors reporting successful results. However, the optimal management of massive rotator cuff tears is controversial and evolving. In general, a massive rotator cuff tear (MRCT) is...

INTRODUCTION Degenerative rotator cuff tears are a common problem, affecting greater than 30% of the general population [1]. Rotator cuff tears most commonly occur in the supraspinatus tendon near the insertion site [2]. There is a high failure rate of rotator cuff tear repairs, and this failure typically occurs at the tendon-suture interface [3]. By determining localized differences in rotator...
