BackgroundRotator cuff injury is a common clinical disorder of the musculoskeletal system. It is one of the most common causes of shoulder pain and shoulder joint dysfunction. Intra-articular injection therapy is one of the common conservative treatments for rotator cuff injury in clinical practice, but scholars have been controversial about the different drugs used for injection therapy and their clinical effectiveness, and there is no complete agreement on the choice of different injectables, and the existing original studies are mostly direct comparisons in 1 arm, lacking indirect comparisons, making it difficult to have a clear and comprehensive understanding.ObjectiveA network Meta-analysis was used to comprehensively compare the effectiveness of drug injection therapies for rotator cuff injuries.MethodsThe PubMed, The Cochrane Library, EMbase, Chinese national knowledge infrastructure, Chinese BioMedical Literature on disc, China Science and Technology Journal Database, and Wan-Fang databases were searched for randomized controlled trials on the effectiveness of steroid injections for the comparative treatment of rotator cuff injury for the period April 19, 2013 to April 19, 2022 (the last decade). Two investigators independently screened the literature, extracted data according to inclusion and exclusion criteria, and evaluated the quality of the literature in parallel. Statistical analysis was performed using Stata 16.0 software to compare the differences in efficacy of each treatment measure and rank the efficacy using the ratio and 95% confidence interval (CI) as the effect indicator.Results10 RCTs with a total of 861 patients with rotator cuff injury were included, involving 4 therapeutic measures: corticosteroid injection therapy (COR), platelet-rich plasma injection therapy (PRP), Hyaluronic acid injection therapy (HA), and prolotherapy therapy (PRO).Meta-analysis results showed that the ranking results of the 4 therapeutic measures were: corticosteroid injection + hyaluronic acid injection > platelet-rich plasma injection + corticosteroid injection > corticosteroid injection > platelet-rich plasma injection > PRO > platelet-rich plasma injection + hyaluronic acid injection > hyaluronic acid injection.Conclusionwe recommend that corticosteroid injections combined with hyaluronic acid injections can be used for the non-surgical conservative clinical management of rotator cuff injuries.Copyright © 2022 the Author(s).
