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...

PURPOSE To examine the prognostic indicators associated with outcome following rotator cuff surgery. METHODS A retrospective evaluation of records on 1120 shoulders (1067 patients) with rotator cuff tear treated by surgery was performed. Preoperative, intra-operative and postoperative factors were analysed by Kendall's Tau-b correlation analysis and logistic regression analysis. RESULTS Pos...

The diagnosis of chronic lesions of the rotator cuff is challenging. We have developed a new index to improve the sonographic diagnosis of chronic tears of the cuff. In a pilot study, we examined 50 asymptomatic healthy volunteers by ultrasound to establish the diameter of the rotator cuff in relation to the tendon of the long head of biceps. Subsequently, the index was calculated in 64 patient...

BACKGROUND Surgical treatment of rotator cuff tears has consistently demonstrated good clinical and functional outcomes. However, in some cases, the rotator cuff fails to heal. While improvements in rotator cuff constructs and biomechanics have been made, the role of biologics to aid healing is currently being investigated. METHODS A selective literature search was performed and personal surg...

BACKGROUND Acromioplasty for impingement syndrome of the shoulder is one of the most common orthopaedic surgical procedures. The rate with which this procedure is performed has increased dramatically. This investigation sought high levels of evidence in the published literature related to five hypotheses pertinent to the concept of the impingement syndrome and the rationale supporting acromiopl...

Background: For surgical treatment of symptomatic partial rotator cuff tears, 2 repair techniques, i.e., arthroscopic trans-tendon repair and arthroscopic repair after conversion to full thickness tear, were widely used and satisfactory clinical outcomes have been reported. However, no study has seen for the direct evaluation of repair integrity after arthroscopic rotator cuff repair using seco...

Ultrasound is gradually achieving more acceptance by orthopaedic surgeons as a diagnostic imaging tool for rotator cuff and biceps tendon pathology. Two hundred and ten patients with arthroscopic rotator cuff repairs were examined clinically and with ultrasound at early (3 weeks) and late follow-up (average 22 months; range: 12 to 49). A high correlation between clinically intact cuffs and sono...

Arthroscopic rotator cuff repair is being performed by an increasing number of orthopaedic surgeons. The principles, techniques, and instrumentation have evolved to the extent that all patterns and sizes of rotator cuff tear, including massive tears, can now be repaired arthroscopically. Achieving a biomechanically stable construct is critical to biologic healing. The ideal repair construct mus...

The purpose of this study was to clinically examine the relationship between rotator cable integrity and the presence of pseudoparalysis. A retrospective review was performed of a consecutive series of arthroscopic repairs of massive rotator cuff tears performed between January 2007 and June 2009. A total of 127 massive tears were identified. Group 1 comprised 24 patients with preoperative pseu...
