Abstract (original English)

Purpose To compare the efficacy of steroid injections to other injectable therapies in partial-thickness rotator cuff (RC) tears. Methods A systematic literature search was performed until October 25, 2021, in 3 databases (Cochrane Central Register of Controlled Trials, Embase, MEDLINE). Eligible studies compared the efficacy of steroid, hyaluronic acid (HA), platelet-rich plasma (PRP), the combination of HA and PRP (HA + PRP), and adipose-derived regenerative cells in RC tears. The primary outcomes were the visual analog scale (VAS), Constant-Murley Shoulder Outcome Score (CMS) and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form. Using paired and network meta-analysis, we calculated pooled mean differences (MDs) with 95% confidence intervals (CIs). Results We included a total of 7 articles in the quantitative synthesis. In shorter periods, the HA + PRP combination was superior to the other substances we investigated (HA + PRP: VAS [0-4 weeks]: MD: -0.99 [95% CI, -1.62 to -0.36]; CMS [0-3 months]: 20.56 [95% CI, 16.18 to 24.94]. This combination was followed by the use of HA or PRP alone, depending on the duration of follow-up and the outcome being studied. In our study, short-term results suggest that saline is superior to steroids for partial tears, but this trend is reversed at 6-month follow-up. Conclusions The HA and PRP combination is currently
