BACKGROUND Literature regarding the outcomes of revision rotator cuff repair is limited. The purposes of the present study were to report the tendon repair integrity and clinical outcomes for a cohort of patients following revision arthroscopic rotator cuff repair and to examine factors related to tendon healing and the influence of healing on clinical outcomes. METHODS Twenty-one of twenty-n...

objective: due to the frequent use of surface electromyography as a tool for the study of muscle function, to accurately compare electromyographic data from different muscles and different subjects, it is necessary to normalize the integrated data obtained from each muscle. the most common normalization technique is the use of maximum voluntary isometric contraction (mvic) of a predetermined is...

[Purpose] The purpose of this study was to analyze the effect of an active vibration stimulus exercise according to shoulder joint angles on functional reach and stability of the shoulder joint. [Subjects and Methods] Thirty healthy male students participated in this study. Upper limb length of each subject was measured to obtain normalized measurement values. The exercise groups were as follow...

PURPOSE The purpose of this study was to report on a difficult patient population and to critically evaluate the role of revision arthroscopic stabilization surgery. METHODS Eighteen patients with failed traumatic instability repairs were treated with revision arthroscopic labral fixation and plication with a mean follow-up of 29.7 months (range, 24 to 48 months). There were 15 male patients ...

BACKGROUND Psychologic distress contributes to symptom severity in patients with several musculoskeletal disorders. While numerous shoulder outcome instruments are used it is unclear whether and to what degree psychologic distress contributes to the scores. QUESTIONS/PURPOSES We asked (1) to what degree shoulder outcome instruments reflect patients' psychologic distress, and (2) whether patie...

BACKGROUND To prospectively evaluate patients who underwent a "mini-open" repair versus a completely arthroscopic technique for small to large size rotator cuff tears. METHODS Fifty-two patients underwent "mini-open" or all arthroscopic repair of a full thickness tear of the rotator cuff. Patients who complained of shoulder pain and/or weakness and who had failed a minimum of 6 weeks of physi...

Background: It is unclear whether hemiarthroplasty (HA) or reverse shoulder arthroplasty (RS) are superior for patientswith cuff tear arthropathy (CTA) and preserved preoperative motion (elevation >90˚).Methods: This was a retrospective, single institution study. Patients who underwent RSA or HA for CTA were included ifthey had preserved preoperative motion with a minimum of 2...
