Surgical repair is the preferred method of treatment of acute Achilles ruptures in North America because, despite a higher risk of overall complications, it offers a reduced risk of re-rupture. However, more recent trials, particularly those using functional bracing with early range of motion (ROM) have challenged this statement. This meta-analysis aims to compare surgical to conservative treatment in respect to re-rupture, overall complications, return to work, calf circumference and functional outcomes, as well as to examine the effects of early ROM on re-rupture rate. Literature search, data extraction, and quality assessment were conducted by two independent reviewers. Publication bias was assessed using the Eggar and Begg tests. Heterogeneity was assessed using I2 tests. Fixed or random-effects models were used accordingly. Pooled results were expressed as risk ratios, risk differences, and weighted or standardized mean difference, as appropriate. Meta-regression was employed to identify heterogeneity causes. Sub-group analysis was performed to assess the effect of early ROM.Purpose
