The etiology of rotator cuff tendinopathy is multi-factorial, and has been attributed to both extrinsic and intrinsic mechanisms. Extrinsic factors that encroach upon the subacromial space and contribute to bursal side compression of the rotator cuff tendons include anatomical variants of the acromion, alterations in scapular or humeral kinematics, postural abnormalities, rotator cuff and scapu...

The purpose of this systematic review was to address the treatment of rotator cuff tears by applying tissue engineering approaches to improve tendon healing, specifically platelet rich plasma (PRP) augmentation, stem cells, and scaffolds. Our systematic search was performed using the combination of the following terms: "rotator cuff", "shoulder", "PRP", "platelet rich plasma", "stemcells", "sca...

For the past few decades, the repair of rotator cuff tears has evolved significantly with advances in arthroscopy techniques, suture anchors and instrumentation. From the biomechanical perspective, the focus in arthroscopic repair has been on increasing fixation strength and restoration of the footprint contact characteristics to provide early rehabilitation and improve healing. To accomplish t...

BACKGROUND Degenerative rotator cuff tears are a significant cause of shoulder pain in the aging population. Rotator cuff repair surgery may be more successful when growth factors are delivered to the repair site. This study was designed to determine the cellular processes involved in normal bone-to-tendon healing and the current approaches used for biologic augmentation of rotator cuff repair....

Purpose Rotator cuff tears and cervical spondylotic amyotrophy (CSA) are often confused as the main symptom in those with difficulty in shoulder elevation. Empty and full can tests are frequently used for the clinical diagnosis of rotator cuff tears. The aim of the present study was to investigate whether the empty and full can test results can help differentiate rotator cuff tears from CSA. ...

CONTEXT Little is known about pitching performance or lack of it among Major League Baseball (MLB) pitchers who undergo operative treatment of rotator cuff tears. OBJECTIVE To assess pitching performance outcomes in MLB players who needed operative treatment of rotator cuff tears and to compare performance in these athletes with that in a control group of MLB players. DESIGN Case-control st...

BACKGROUND Among the many causes of rotator cuff tears, scapular morphology is associated with the accelerating degenerative process of the rotator cuff. Acromion index (AI) was previously introduced and compared in two populations. METHODS We enrolled 100 Korean patients diagnosed with full-thickness rotator cuff tears by magnetic resonance imaging and intraoperative arthroscopic findings be...

PURPOSE OF THE STUDY The aim of this study is to present a simple rotator cuff lesion classification that provides guidelines as to their treatment, and to evaluate the results of palliative arthroscopic resection of rotator cuff residues known as unreconstructible lesions. In addition, our therapeutic approaches were ascertained in view of their applicability to the types of lesions studied. ...

INTRODUCTION: Rotator cuff tears are a common condition, affecting approximately 50% of the population over the age of 60 [1]. The etiology of rotator cuff tears is not well understood, but it is widely believed that abnormal glenohumeral joint (GHJ) motion leads to subacromial impingement and the development of rotator cuff tears [2]. The treatment of rotator cuff tears is based implicitly on ...

Rotator cuff arthropathy is often associated with disabling pain and shoulder dysfunction. When non operative treatment options have failed, reverse shoulder replacement is usually indicated. Alternative treatment options may be prudent in younger patients, those with multiple co morbidities compromising surgical options, or those unable to comply with postoperative rehabilitation. There is lit...
