Abstract

Objective: To compare the rerupture rate after conservative treatment, open repair, and minimally invasive surgery management of acute Achilles tendon ruptures.

Design: Systematic review and network meta-analysis.

Data sources: We searched Medline, Embase, and the Cochrane Central Register of Controlled Trials from inception to August 2022.

Methods: Randomised controlled trials involving different treatments for Achilles tendon rupture were included. The primary outcome was rerupture. Bayesian network meta-analysis with random effects was used to assess pooled relative risks (RRs) and 95% confidence intervals. We evaluated the heterogeneity and publication bias.

Results: Thirteen trials with 1465 patients were included. In direct comparison, there was no difference between open repair and minimally invasive surgery for rerupture rate (RR, 0.72, 95% CI 0.10-4.4; I2 = 0%; Table 2). Compared to the conservative treatment, the RR was 0.27 (95% CI 0.10-0.62, I2 = 0%) for open repair and 0.14 (95% CI 0.01-0.88, I2 = 0%) for minimally invasive surgery. The network meta-analysis had obtained the similar results as the direct comparison.

Conclusion: Both open repair and minimally invasive surgery were associated with a significant reduction in rerupture rate compared with conservative management, but no difference in rerupture rate was found comparing open repair and minimally invasive surgery.
