Abstract
BACKGROUND: Treatment of rotator cuff diseases often involves various arthroscopic procedures but their combined effectiveness remains contentious, especially in complex cases. METHODS: We focused on patients with degenerative shoulder cuff diseases requiring arthroscopic rotator cuff repair. Searches covered multiple databases (Medline, Embase, Web of Science, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Cochrane Clinical Answers) up to April 1, 2024. Bias risk was assessed using RevMan (v 5.4), and a network meta-analysis was conducted with netmeta (v 2.8). RESULT: From 16 studies, 1232 patients (average age, 56.2 years; balanced sex ratio) were included. Arthroscopic rotator cuff repair ranked highest in functional score networks, surpassing other interventions. Physiotherapy was superior for pain relief compared to arthroscopic procedures combined with platelet-rich plasma (mean, 2.5; 95% confidence interval, 4.48-0.52). Arthroscopic rotator cuff repair and subacromial decompression were significantly superior to arthroscopic rotator cuff repair and subacromial decompression combined with platelet-rich plasma (MD, 1.80; 95% CI, 3.39-0.21). DISCUSSION: Moderate bias risks were noted in both networks due to blinding issues and methodological quality reporting. Arthroscopic rotator cuff repair is favored for improving shoulder function, while other procedures or intra-articular treatments offer no significant benefits. Regarding pain management, physiotherapy is preferred; however, more evidence is needed to support this recommendation and caution is advised.
