Postoperative progression of muscle atrophy correlates with tendon integrity after rotator cuff repair, and preoperative MRI baselines may overestimate atrophy.
Muscle atrophy has been established as a predictor of failure after rotator cuff repair. Traditionally, preoperative magnetic resonance imaging has been used as a baseline for subsequent comparison. Use of a preoperative baseline may overestimate the degree of atrophy present. In addition, postoperative progression of atrophy correlates with the integrity of the tendon.
