BackgroundPrevious studies have reported that both arthroscopic debridement (AD) and open debridement (OD) of extensor carpi radialis brevis are effective in the treatment of lateral epicondylitis. Despite this, few studies have focused on the comparative outcomes of these 2 procedures. The aim of this study was to assess whether AD is superior to OD in managing lateral epicondylitis.MethodsA systematic search of the literature was conducted to identify relevant articles that were published in MEDLINE, Embase, and Cochrane Library databases during January 2019. All studies comparing the efficacy of AD and OD in terms of failure rate, complication rate, and clinical outcome measures were included. Statistical analysis was performed using Review Manager.ResultsSix clinical trials were included in the current meta-analysis. There was no significant difference with regard to disabilities of the arm, shoulder, and hand scores, visual analog scale, and failure rate. There was a statistically significant difference in surgical time in favor of the OD (mean difference [MD], -11.45, 95% confidence interval [CI], -12.45 to -10.44, I = 0%, P < .001). There was no significant difference of complication rate between the OD group (0.6%) and the AD group (1.0%) (MD, 0.62; 95% CI, 0.12-3.06; P = .55) CONCLUSION:: There was no significant difference between arthroscopic and open surgery with regards to failure rate, functional outcome score, and complication rate. The current meta-analysis found that arthroscopic surgery had a longer surgical time than open surgery for lateral epicondylitis.
