Arthroscopic subscapularis repair with knotted suture fixation typically requires use of both anterior and accessory superolateral portals with passage of suture through multiple anatomic spaces. The advent of knotless anchors has allowed for simplification of subscapularis repairs. In this report we describe a simple method of knotless arthroscopic subscapularis repair through a single anterio...

OBJECTIVE To evaluate the functional and clinical outcomes and identify prognostic factors in patients undergoing arthroscopic repair of isolated tears of the subscapularis tendon. METHODS Between January 2003 and May 2009, we identified 18 shoulders with isolated tears or deinsertions that were complete or affected at least one third of the subscapularis tendon and underwent arthroscopic rep...

The rotator cuff is comprised of the supraspinatus, infraspinatus, subscapularis, and teres minor muscles and tendons. The four muscles of the rotator cuff act as stabilizers of the glenohumeral joint. The supraspinatus is primarily a shoulder abductor. The supraspinatus muscle originates along the dorsal surface of the scapula. The muscle fibers course in a lateral orientation and converge to ...

HYPOTHESIS Many authors suggest that subscapularis deficiency after shoulder arthroplasty has a negative effect on long-term outcomes. Thus, increasing emphasis has been placed on the technique for repair of the tendon. This study evaluated the biomechanical strength of 3 different repairs: osteotomy, tendon to bone, and a combined method. MATERIALS AND METHODS Twenty-four paired shoulders fr...

O w large body of evidence supports the fact that ubluxation and dislocation of the long head of the iceps tendon are relatively common findings associted with rotator cuff pathology. Dislocation of the ong head of the biceps is often linked to chronic egenerative changes seen with impingement synrome and tears in the rotator cuff, especially the ubscapularis tendon. One report states that medi...

HYPOTHESIS Dislocation is the most common serious complication after reverse shoulder arthroplasty. One theorized cause is subscapularis insufficiency because the tendon cannot be repaired at the time of surgery. There are no documented risk assessments of reverse total shoulder arthroplasty dislocation related to this cause. The study objective was to quantify the risk of postoperative disloca...

PURPOSE To assess diagnostic accuracy in the detection and grading of subscapularis tendon lesions at magnetic resonance (MR) arthrography. MATERIALS AND METHODS MR arthrograms in 50 consecutive patients (29 with normal subscapularis tendons, 11 with a lesion in the cranial quarter, seven with a major tear but not complete detachment, three with complete detachment) with arthroscopic or surgi...

A 13-year-old right-hand-dominant skeletally immature boy presented to the authors' clinic after being blocked during an overhead dodgeball throw and hearing an abrupt "pop" in the shoulder. He had pain in the subdeltoid region that was most prominent during sports-related activity, particularly throwing. The patient had nonoperative management of a lesser tuberosity avulsion fracture 1 year ea...

CASE In this case report, we presented the case of an adolescent tennis player with avulsion injury of the subscapularis tendon of the right shoulder. PATIENTS A 17-year-old right-hand-dominant male tennis player visited our hospital complaining of pain in the anterior aspect of the right shoulder. We performed X-ray and three-dimensional computed tomography (3D-CT) and magnetic resonance ima...

We evaluated whether matrix metalloproteases and their inhibitors are involved in extracellular matrix remodelling and degradation of chronic rotator cuff tears. Tendon samples were harvested from 13 patients who underwent arthroscopic repair of a rotator cuff tear. Supraspinatus specimens were harvested en bloc from the arthroscopically intact middle portion of the tendon, more than 1 cm later...
