To compare the effect of steroid injection and physiotherapy for patients with adhesive capsulitis of the shoulder (ACS). An electronic search was performed on PubMed, Embase, and Cochrane Library, and reference lists were also reviewed for randomized controlled trials (RCTs) comparing steroid injection and physiotherapy for patients with ACS. The quality of included studies were assessed using PEDro scale. Standardized mean differences (SMDs) and 95% confidence interval (CI) were used for comparisons. The primary outcome was functional improvement. Nine RCTs including 453 patients were identified. From 6 to 7 weeks to 24 to 26 weeks postintervention, no superiority was noted in favor of either steroid injection or physiotherapy for functional improvement (SMD 0.28; 95% CI -0.01 to 0.58; p = 0.06) or pain relief (SMD -0.10; 95% CI -0.70 to 0.50; p = 0.75). Steroid injection provided more improvement in passive external rotation at 24 to 26 weeks (3 studies, SMD 0.42; 95% CI 0.11 to 0.72; p = 0.007) but not at 6 to 7 weeks (4 studies, SMD 0.63; 95% CI 0.36 to 0.89; p = 0.32) or 12 to 16 weeks (3 studies, SMD -0.07; 95% CI -0.79 to 0.65; p = 0.85). Steroid injection was as safe as physiotherapy for patients with ACS (risk ratio 0.94; 95% CI 0.67 to 1.31). Both steroid injection and physiotherapy are equally effective for patients with ACS. One steroid injection might be the 1st choice for ACS. Results should be interpreted with caution due to the heterogeneity among the studies.
