Surgical management for massive rotator cuff tears: a network meta-analysis of randomized controlled trials.

Abstract

Background: Multiple surgical strategies have been developed for treating massive rotator cuff tears (mRCTs). However, there is still no consensus on the best surgical option for mRCTs. Through a network meta-analysis, we aimed to comprehensively and systematically analyse the evidence in randomized controlled trials to help clinicians make evidence-based clinical decisions for patients with mRCTs.

Methods: Our study was a network meta-analysis of the surgical management of mRCTs (PROSPERO Registration ID: CRD42023397971). We searched PubMed, EMBASE, Cochrane and Web of Science for randomized controlled trials that examined the efficacy of surgical management for mRCTs up to 3 November 2022. A three-step method was employed for the study process. Study selection, data extraction and risk of bias evaluation were conducted by two independent reviewers. R software (version 4.2.1) and Stata (version 15.1) were used for the data analysis.

Results: From 10,633 publications, we included 15 randomized controlled trials (996 participants) for the quantitative analysis. In terms of both long-term and short-term surgical effects, there were no statistically significant differences among surgical interventions such as patch-augmented rotator cuff repair (RCR), RCR with platelet-rich plasma, arthroscopic decompression, bridging reconstruction, arthroscopic RCR with platelet-leukocyte membrane, open RCR, mini-open RCR, arthroscopic debridement, superior capsular reconstruction, arthroscopic suture-spanning augmented repair, subacromial balloon spacer and latissimus dorsi tendon transfer. Based on algorithms, the probability ranking suggests that patch augmentation is the most highly ranked surgical intervention for achieving better short-term surgical outcomes. Furthermore, arthroscopic-associated mini-open RCR was ranked as the highest surgical intervention for achieving better long-term surgical effects.

Conclusions: Based on the available data from the included studies, similar surgical efficacies were observed among the reported intervention measures for mRCTs. The patch augmentation technique was found to potentially achieve better short-term surgical outcomes, which is consistent with previous reports. However, the best surgical interventions for achieving long-term surgical effects remain unknown. More high-quality research is needed to evaluate the efficacy and safety of these interventions and to guide clinical practice.
