Clinical effect of reconstruction of single-bundle versus double-bundle posterior cruciate ligament under arthroscopy: a Meta-analysis

doi:10.3969/j.issn.2095-4344.0234

Abstract

Abstract:

BACKGROUND: Arthroscopic surgery is often used for posterior cruciate ligament injury, but the specific reconstruction method is still controversial. The clinical efficacy of single-bundle and double-bundle
reconstruction still remains unclear.
OBJECTIVE: To evaluate the clinical efficacy of arthroscopic single-bundle versus double-bundle posterior cruciate ligament reconstruction.
METHODS: PubMed, Embase, the Cochrane library, CNKI, and WanFang databases were retrieved for the articles addressing the curative effect of arthroscopic single-bundle versus double-bundle posterior cruciate ligament reconstruction. Based on the inclusion and exclusion criteria, the literature screen and quality assessment were conducted by two researchers, and a Meta-analysis was performed on Revman5.3 software.
RESULTS AND CONCLUSION: A total of 11 eligible articles were included, including 5 randomized controlled trials and 6 non-randomized controlled trials, involving 529 cases of posterior cruciate ligament injury. Meta-analysis results showed that the postoperative International Knee Documentation Committee scores in the double-bundle reconstruction group were superior to those in the single-bundle reconstruction group (RR=0.88, 95%CI (0.79, 0.98), P=0.02]. The postoperative Lysholm score (MD=-0.68, 95%CI (-1.59, 0.24), P=0.15) and Tegner scores (MD=-0.16, 95%CI (-0.37, 0.04), P=0.12) showed no significant difference between two groups. The knee flexion 90° to the evaluation of the stability in double-bundle reconstruction group was superior to that in the single-bundle reconstruction group (MD=1.07, 95%CI (0.28, 1.87), P=0.008). In summary, both reconstructions are effective, only in the knee stability and International Knee Documentation Committee scores, double-bundle posterior cruciate ligament reconstruction is superior to single-bundle posterior cruciate ligament reconstruction. However, because of the quality and size of the literature included, more high quality randomized controlled trials need to be collected for in-depth investigation.
