Purpose: To compare range of motion and healing rates between 2 different rehabilitation protocols after arthroscopic single-row repair for full-thickness rotator cuff tear. Methods: Sixty-four shoulders available for postoperative magnetic resonance imaging (MRI) evaluation after arthroscopic rotator cuff repair were enrolled in this study. Aggressive early passive rehabilitation (manual therapy [2 times per day] and unlimited self–passive stretching exercise) was performed in 30 shoulders (group A) and limited early passive rehabilitation (limited continuous passive motion exercise and limited self–passive exercise) in 34 shoulders (group B). A postoperative MRI scan was performed at a mean of 7.6 months (range, 6 to 12 months) after surgery. Results: Regarding range of motion, group A improved more rapidly in forward flexion, external rotation at the side, internal and external rotation at 90° of abduction, and abduction than group B until 3 months postoperatively with significant differences. However, there were no statistically significant differences between the 2 groups at 1-year follow-up (P = .827 for forward flexion, P = .132 for external rotation at the side, P = .661 for external rotation at 90° of abduction, and P = .252 for abduction), except in internal rotation at 90° of abduction (P = .021). In assessing the repair integrity with postoperative MRI scans, 7 of 30 cases (23.3%) in group A and 3 of 34 cases (8.8%) in group B had retears, but the difference was not statistically significant (P = .106). Conclusions: Pain, range of motion, muscle strength, and function all significantly improved after arthroscopic rotator cuff repair, regardless of early postoperative rehabilitation protocols. However, aggressive early motion may increase the possibility of anatomic failure at the repaired cuff. A gentle rehabilitation protocol with limits in range of motion and exercise times after arthroscopic rotator cuff repair would be better for tendon healing without taking any substantial risks. Level of Evidence: Level II, randomized controlled trial. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to evaluate the clinical and radiologic results of arthroscopic tuberoplasty for symptomatic irreparable massive rotator cuff tears. Methods: This study enrolled 32 patients (32 shoulders) who underwent arthroscopic tuberoplasty for irreparable massive rotator cuff tears and were followed up for at least 24 months. The mean patient age at the time of surgery was 62.4 years (range, 43 to 76 years), and the mean duration of follow-up was 40 months (range, 24 to 63 months). The Constant score and the University of California, Los Angeles score were used for clinical evaluation. The acromiohumeral interval and inferior scapulohumeral line continuity were used for radiologic evaluation. Results: Twenty-six shoulders underwent arthroscopic tuberoplasty with concomitant acromioplasty, and 6 shoulders had only arthroscopic tuberoplasty. The Constant score increased from a preoperative mean of 47.6 points to 70.4 points at the last follow-up (P < .001). The University of California, Los Angeles score also improved from a preoperative mean of 15.4 points to 27.1 points at the last follow-up (P < .001), with 3 shoulders (9%) rated as excellent, 23 (72%) as good, and 6 (19%) as poor. The active range of forward flexion improved from 115.9° to 142.7° (P = .024). The final outcomes were not statistically affected by sex, age, preoperative mobility, and existence of a lesion of the long head of the biceps tendon. However, preoperative acromiohumeral interval and inferior scapulohumeral line continuity were statistically correlated with the final results (P < .001 and P = .047, respectively). Conclusions: Arthroscopic tuberoplasty with concomitant acromioplasty, as well as treatment of the biceps tendon when indicated, would be an option for diminishing pain and improving active forward elevation for irreparable massive rotator cuff tears. In particular, satisfactory results during the minimum follow-up period of 24 months can be achieved in the cases with good preservation of the preoperative and postoperative acromiohumeral interval and continuity in the inferior scapulohumeral line, regardless of preoperative mobility. Level of Evidence: Level IV, therapeutic case series. [Copyright &y& Elsevier]
