Abstract:
Objective:To compare the arthroscopic autologous osteochondral transfer (AOT) and arthroscopic subscapularis augmentation (ASA) in the treatment of recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20%.Methods:A retrospective analysis was conducted of the clinical data of 42 patients who had been treated at Department of Orthopaedics, The Second Hospital of Lanzhou University for recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20% from January 2022 to January 2023. There were 30 males and 12 females, with an age of (32.2±15.2) years. Altogether 12 left shoulders and 30 right shoulders were affected. The patients were divided into 2 groups according to their surgical methods: an AOT group in which 15 cases were treated with AOT and an ASA group in which 27 cases treated with ASA. The Rowe score, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS), and shoulder range of motion were compared between groups at the last follow-up. All the above indexes were compared between pre-surgery and post-surgery in each group. The incidence of complications in the 2 groups was recorded.Results:There were no statistically significant differences in the preoperative general data between the 2 groups, indicating comparability ( P > 0.05). A total of 42 patients were followed up for (17.2±5.9) months after surgery. At the last follow-up, in the ASA group and the AOT group respectively, the Rowe score was (97.0±4.4) points and (98.3±2.4) points, the ASES score (97.9±5.2) points and (99.1±3.7) points, and the VAS score 0 (0, 0) point and 0 (0, 1) point, showing no significant difference between the 2 groups ( P > 0.05). The above items in the 2 groups were significantly improved compared with those before surgery ( P < 0.05). At the last follow-up, in ASA group and AOT group respectively, shoulder abduction was 169.2°±3.0° and 168.3°±3.1°, and flexion 171.9°±4.0° and 173.3°±4.1°, showing no significant difference between the 2 groups ( P > 0.05); the abduction 90° external rotation was 67.3°±3.2° in the AOT group, significantly better than that in the ASA group (64.4°±3.5°) ( P < 0.05). The above items in the 2 groups were significantly improved compared with those before operation ( P < 0.05). Follow-ups revealed no infection or osteoarthritis. After surgery, 1 case of shoulder re-dislocation and 6 cases of shoulder pain occurred in the ASA group, while no cases of shoulder re-dislocation or shoulder pain occurred in the AOT group. There was no significant difference between the 2 groups in the incidence of complications ( P > 0.05). Conclusions:In the treatment of patients with recurrent anterior shoulder dislocation complicated with scapular glenoid bone injury less than 20%, both AOT and ASA can improve shoulder function, but AOT is superior to ASA in 90° external rotation.
