Preserving-remnant versus removing-remnant for arthroscopic anterior cruciate ligament reconstruction: a Meta-analysis

doi:10.3969/j.issn.2095-4344.2016.20.019

Abstract

Abstract:

BACKGROUND: There are controversies about preserving the remnant in the anterior cruciate ligament reconstruction procedure because of its uncertain therapeutic effects.
OBJECTIVE: To compare the efficacy and safety of preserving-remnant with removing-remnant for arthroscopic anterior cruciate ligament reconstruction using a meta-analysis.
METHODS: A computer-based online search was conducted in PubMed, Embase, the Cochrane Library, CDSR, CBM, and CNKI databases by using the English key words of “anterior cruciate ligament AND remnant (OR stump) AND randomized controlled trial (RCT) OR quasi-RCT” and the Chinese key words of “anterior cruciate ligament reconstruction, preserving-remnant, removing-remnant” to screen the relevant articles published from 1995 to July 2015. Meta-analysis was performed using Review Manager 5.3 software.
RESULTS AND CONCLUSION: A total of 13 randomized controlled trials were included. The meta-analysis results showed that there were no statistically significant differences in KT1000/2000 scores (OR=-0.28, 95%CI: -0.76-0.20, P=0.25), the good rate of synoveal coverage (OR =-0.30, 95%CI: -0.30-0.90, P=0.32), and the incidence of cyclops leions (OR=0.87, 95%CI: 0.63-2.90, P=0.44). Postoperative Lysholm scores (OR=2.45, 95%CI: 0.52-4.39, P=0.01), proprioceptive function (OR=-1.72, 95%CI: -3.32 to 0.13, P=0.03), tunnel enlargement (OR=-0.66, 95%CI: -1.08 to -0.23, P=0.002) in preserving-remnant were superior to removing-remnant for arthroscopic anterior cruciate ligament reconstruction. These results suggest that both preserving-remnant and removing-remnant for arthroscopic anterior cruciate ligament reconstruction can obtain satisfactory antero-posterior stability of the knee. Preserving-remnant exhibits superiority in post-operative scores of the knee, proprioceptive function, tunnel enlargement. Further high-quality randomized controlled trials are warranted because of some low-quality studies and the existing biases.
