Efficacy of augmentation versus direct suture for repairing acute Achilles tendon ruptures: a Meta-analysis / 中华创伤杂志

ABSTRACT

Objective:To compare the efficacy of augmentation suture and direct suture in treatment of acute Achilles tendon ruptures so as to provide evidences for the selection of surgical methods.Methods:A systematic search was conducted in PubMed, Web of Science, EMBASE, CNKI and Wanfang database for studies of augmentation suture versus direct suture of acute Achilles tendon ruptures. Literatures were retrieved from January 1990 to January 2019. Literatures were screened according to the pre-set inclusion and exclusion criteria, and the rating of included literature was strictly evaluated by the Cochrane System Evaluation Manual and Newcastle-Ottawa scale (NOS). The relevant data were analyzed using RevMan 5.3 to compare patient satisfaction, rerupture rate, infection rate, ankle's range of motion and other complications (postoperative calf atrophy, plantar flexion, plantar flexion strength).Results:Eight articles involving 558 patients were identified including 273 patients in augmentation suture group and 285 patients in direct suture group. There were no significant differences between two groups in aspects of patient satisfaction ( OR=1.00, 95% CI 0.54-1.84, P>0.05), rerupture rate ( OR=0.75, 95% CI 0.34-1.66, P>0.05), infection rate ( OR=1.73, 95% CI 0.76-3.94, P>0.05), ankle's range of motion ( OR=0.97, 95% CI 0.33-2.87, P>0.05) and other complications rate ( OR=1.93, 95% CI 0.91-4.09, P>0.05). Meantime, the two groups showed similar effect on postoperative calf atrophy and average isokinetic calf muscle strength ( P>0.05). There was a significant difference in plantar flexion of injured limbs after augmentation suture( P<0.05). Conclusion:Compared with direct suture, augmentation suture cannot improve patient satisfaction or reduce complication rate in repair of acute Achilles tendon ruptures.
