Abstract:
Objective:To compare the outcomes between the arthroscopic en masse repair and the modified separate repair for type Ⅰ delaminated rotator cuff tears.Methods:This retrospective study analyzed the clinical data of 46 patients who had been treated for delaminated rotator cuff tears at Department of Sports Medicine, The Second People's Hospital of Fujian Province from January 2021 to January 2023. This cohort consisted of 15 males and 31 females, with an age of (58.2±9.0) years. Their delaminated rotator cuff tears were all classified as typeⅠ according to Choo et al. According to different surgical methods, they were divided into 2 groups: group A (22 cases) was treated by arthroscopic en masse repair while group B (24 cases) by arthroscopic modified separate repair. The 2 groups were compared in terms of forward flexion, external rotation, internal rotation, visual analogue scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, and Constant-Murley score at preoperation and the last follow-up. MRI was used to evaluate the healing status of rotator cuff at the last follow-up.Results:There was no significant difference in the baseline data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for 26.0 (24.0, 28.0) months. At the last follow-up, the external rotation (57.3°±15.7°), ASES score [(97.5±3.6) points] and Constant-Murley score [(93.7±3.0) points] in group B were significantly better than those in group A [40.9°±17.7°, (85.5±18.3) points, and (78.6±22.7) points] ( P<0.05), but the differences in forward flexion, internal rotation or VAS pain score were not significantly different between the 2 groups ( P>0.05). In both groups A and B, significant improvements were achieved at the last follow-up in forward flexion, external rotation, internal rotation, VAS pain score, ASES score, and Constant-Murley score compared with the preoperative period ( P<0.05). At the last follow-up, in group A and group B respectively, the rotator cuff was completely healed in 9 and 18 cases, partially healed in 10 and 6 cases, and re-torn in 3 and 0 cases, showing significant differences in the healing status between the 2 groups ( P<0.05). Conclusion:In the treatment of type Ⅰ delaminated rotator cuff tears, the modified separate repair can obtain significantly better external rotation, ASES score, Constant-Murley score, and healing status of rotator cuff than the arthroscopic en masse repair.
