Abstract This systematic review determined the effectiveness of the Unna boot in the treatment of venous leg ulcers (VLUs) by assessing the quality of the available evidence. A systematic search of studies published between August 2019 and February 2020 was conducted using the PubMed, PubMed/PMC, BVS/BIREME, CINAHL, Web of Science, MEDLINE, Embase, Cochrane, ProQuest, BDTD, CAPES Thesis and Dissertation, OPEN THESIS, Centre for Reviews and Dissemination and SciELO databases. Studies were eligible if they reported primary studies, controlled clinical trials, quasi‐experimental studies or observational studies (cross‐sectional studies or cohort studies). We identified 302 articles. After screening and critical appraisal, eight articles were included in this review, while six articles were included in the meta‐analysis. Four studies were included in the outcome of complete ulcer healing rate with a weighted estimate of the odds ratio of 0.43 (95% CI = 0.188–1.01). No evidence of the presence of considerable heterogeneity was observed ( p = 0.35, I 2 = 32%). Two studies were assigned to the outcome time to complete ulcer healing (days) with a weighted estimated mean difference of 41.3 days (95% CI = 21.62–61.04). Evidence of the presence of considerable heterogeneity was observed ( p = 0.01, I 2 = 85%). The results showed a moderate degree of evidence that there is no difference in the healing rates of VLUs with the use of the Unna boot. For the time to complete ulcer healing, the low number of studies and low classification impaired the reporting at any level of evidence.
