However, the potential adverse effects of tourniquet use have gained increasing attention from clinical researchers. We conducted this systematic review and meta-analysis to compare the clinical outcomes of tourniquet application versus non-tourniquet approach during arthroscopic ACL reconstruction.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>A comprehensive search of PubMed, Web of Science, Embase, and Cochrane Library databases, was performed through March 2023 to identify controlled clinical trials. The main outcomes assessed included post-operative drain output, post-operative pain using a visual analogue scale (VAS), operation time, calf girth, and thigh girth. A random-effects meta-analysis was performed to account for heterogeneity, with weighted mean difference (WMD) and 95% confidence intervals (CI) used as pooled estimates for clinical outcomes.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Of the nine potentially related studies, seven eligible studies (sufficient quantitative data) were included in the meta-analysis. Postoperative drain output in the tourniquet group was on average 100\u00a0ml higher than in the non-tourniquet group (95% CI: 36 to 168). Pain, measured by the VAS at 24\u00a0h postoperatively, was 0.42 points higher in the tourniquet group (95% CI: 0.08 to 0.76), with the increase persisting at 48\u00a0h, averaging 0.40 points (95% CI: 0.12 to 0.69). Thigh girth in the tourniquet group was reduced by 1.8\u00a0cm (95% CI: -2.7 to -0.94). No significant differences were observed for calf girth and the operation time.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Our meta-analysis indicates that tourniquet use during arthroscopic ACL reconstruction is associated with higher pain levels, increased postoperative drain output, and reduced thigh girth.
