Repaired Rotator Cuff Injuries: Magnetic Resonance Imaging Evaluation
Main Article Content
Abstract
The repaired rotator cuff frequently appears abnormal on magnetic resonance imaging (MRI). Recent studies have shown that while the tendons typically normalize, they can demonstrate clinically insignificant abnormal imaging appearances for longer than 6 months. Features of capsular thickening or subacromial-subdeltoid bursal thickening and fluid distension were found to decrease substantially in the first 6-month postoperative period. MRI was found to be highly comparable in the postoperative assessment of the rotator cuff, although they had a lower sensitivity for partial thickness tears. Imaging evaluation of newer techniques such as patch augmentation and superior capsular reconstruction needs to be further investigated.
