Rotator cuff tear is one of the most common shoulder diseases. It is interesting that some rotator cuff tears are symptomatic, whereas others are asymptomatic. Pain is the most common symptom of patients with a tear. Even in patients with an asymptomatic tear, it may become symptomatic with an increase in tear size. Physical examination is extremely important to evaluate the presence, location,...

BACKGROUND Idiopathic adhesive capsulitis is defined as a frozen shoulder with severe and global range-of-motion loss of unknown etiology. The purpose of our study was to clarify the prevalence of rotator cuff lesions according to patterns and severity of range-of-motion loss in a large cohort of patients with stiff shoulders. METHODS Rotator cuff pathology was prospectively investigated with...

BACKGROUND We compared the clinical course of rotator cuff tears between rotator cuff exercise and bone marrow aspirate concentration (BMAC)-platelet rich plasma (PRP) injection to identify the therapeutic effects of BMAC-PRP on partial tear of the rotator cuff tendon. METHODS Twenty-four patients with partial tear of the rotator cuff tendon participated in this study. Twelve patients underwe...

INTRODUCTION: Rotator cuff tears are a common cause of shoulder pain and disability. Surgical repair of the rotator cuff tears is effective for improvement of shoulder function. The long head of the biceps brachii (LHB) tendon has an important mechanism for humeral head stability and glenohumeral articulation. 1) Several lesions around the LHB tendon associated with rotator cuff tears are repor...

BACKGROUND Normative data are essential to the evaluation of shoulder function. The purposes of this study were to establish a normative database of isometric shoulder strength measured in asymptomatic individuals verified to have intact rotator cuffs and to determine the effect of asymptomatic rotator cuff tears on shoulder strength. METHODS Two hundred and thirty-seven volunteers with no sh...

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...

Ultrasound and magnetic resonance imaging (MRI) are both capable of diagnosing full-thickness rotator cuff tears. However, it is unknown which imaging modality is more accurate and precise in evaluating the characteristics of full-thickness rotator cuff tears in a surgical population. This study reviewed 114 patients who underwent arthroscopic repair of a full-thickness rotator cuff tear over a...

Rotator cuff tear size has an important effect on clinical outcomes after repair. Management options for massive rotator cuff tears are numerous, and selection of the most appropriate treatment method for individual patients can be a challenge. An understanding of the pathomechanics, treatment, and clinical outcomes in patients with massive rotator cuff tears can serve as a guide for clinical d...

BACKGROUND Magnetic resonance imaging (MRI) is considered to be a valuable tool for the diagnosis of rotator cuff tears in patients with severe glenohumeral osteoarthritis who are indicated for total shoulder arthroplasty (TSA). We determined the sensitivity, specificity, and positive predictive value of MRI in diagnosing rotator cuff tears in such patients. METHODS MRI reports of 100 patient...

PURPOSE To compare the accuracy of ultrasonography and magnetic resonance imaging in the detection of rotator cuff tears. MATERIALS AND METHODS Ninety-six patients with clinically suspected rotator cuff pathology underwent ultrasonography and magnetic resonance imaging of the shoulder. The findings in 88 patients were compared with arthroscopy or open surgery. RESULTS Full-thickness tear wa...
