最近，通过设计的缝合技术，大面积袖带撕裂修复后的再撕裂率得到了提高。然而，报告的再撕裂率与术前萎缩和脂肪变性相关。本研究的目的是调查术前肩袖肌肉萎缩和脂肪变性是否通过成功修复得到改善。对24例肩袖大面积撕裂患者术后冈上肌和冈下肌萎缩和脂肪变性的恢复情况进行了评价。萎缩按占位比分类，脂肪变性按改良Goutallier分类。在手术前和手术后对两者进行磁共振成像（MRI）评估。当袖带修复良好时，分别在一半和四分之一的病例中观察到萎缩和脂肪变性的改善。然而，在再撕裂病例中，萎缩和脂肪变性变得更糟。在成功完成肩袖修复术治疗大面积和大量撕裂的病例中，肩袖肌肉萎缩和脂肪变性有望得到改善。
Recently, retear rate after repair for massive cuff tear have been improved through devised suture techniques. However, reported retear rate is relevant to preoperative atrophy and fatty degeneration. The purpose of this study was to investigate whether preoperative atrophy and fatty degeneration of rotator cuff muscles improve by successful repair. Twenty-four patients with massive rotator cuff tear were evaluated on the recovery of atrophy and fatty degeneration of supraspinatus and infraspinatus muscle after surgery. Atrophy was classified by the occupation ratio and fatty degeneration by modified Goutallier's classification. Both were assessed on magnetic resonance imaging (MRI) before and after the operation. When the cuff was well repaired, improvement of the atrophy and fatty degeneration were observed in a half and a one-fourth of the cases, respectively. In retear cases, however, atrophy and fatty degeneration became worse. Improvement of atrophy and fatty degeneration of the rotator cuff muscles may be expected in the cases with successful achievement of rotator cuff repair for large and massive tear.
