Background: The aim of this study is to compare the clinical efficacy between the ligament augmentation reconstruction system (LARS) and the modified Brostrom-Gould (MBG) operations in the treatment of chronic ankle instability.
Methods: We searched the MEDLINE, EMBASE, PubMed, Web of Science, the Cochrane library, and the Clinicaltrial.gov databases for eligible studies. The Review Manager 5.3 software was applied to compare various postoperative functional scoring, ankle stability and complications between the two groups.
Results: Four randomized controlled trials including a total of 209 patients were conducted. No significant difference was found in terms of postoperative FAOS, FAAM, ankle stability and complications between the LARS and MBG group.
Conclusions: The present meta-analysis suggested that there was no clinical superiority for the LARS operation over the MBG operation for patients with chronic ankle instability.
