PurposeTo compare range of motion and healing rates between 2 different rehabilitation protocols after arthroscopic single-row repair for full-thickness rotator cuff tear.MethodsSixty-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.ResultsRegarding 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).ConclusionsPain, 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 EvidenceLevel II, randomized controlled trial.Copyright © 2012 Arthroscopy Association of North America.
