[Meta-analysis of leg length discrepancy after robot-assisted and traditional total hip arthroplasty].

Abstract

Objective: To systematically evaluate the difference in leg length discrepancy (LLD) between robot-assisted total hip arthroplasty (THA) and traditional THA. Methods: The Cochrane Library, PubMed, Web of Science, EMbase, CNKI, Wanfang, VIP, and CBM databases were searched by computer to collect cohort studies of robot-assisted and traditional THAs from inception to August 11th, 2021. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.3 software. Results: >0.05). Conclusion: Robot-assisted THA is superior to traditional THA in postoperative LLD.
