Summary

Prospective study was to compare clinical and radiological outcomes of arthroscopic single-bundle versus double-bundle anterior cruciate ligament reconstruction. There was no statistically significant difference concerning knee stability, knee scores, subjective evaluations & MRI evaluation of graft inclination angles between SB & DB ACL reconstruction groups at an average of 35 months followup

Abstract

Introduction

Aim

of study was to compare clinical and radiological outcomes of arthroscopic single-bundle versus double-bundle anterior cruciate ligament reconstruction. Methods: 60 patients with isolated ACL injury were randomized by chit method into single bundle (SB) (n=30) and double bundle (DB) reconstruction groups (n=30); and were operated by single surgeon between July 2009 to July 2012. Evaluation tools were GeNouRoB (GNRB) arthrometer, International Knee Documentation Committee (IKDC) and Lysholm scale. Magnetic resonance imaging was performed postoperatively to compare the orientation of the reconstructed ACL. Rotational stability was determined by pivot-shift test. Results: At final follow up, mean Lysholm score was 95.13+2.67 in SB group and 93.13 ± 3.31in DB group (P value >0.05 statistically non significant -NS). All patients in both groups were in grade A or B according to objective IKDC scores. Mean differential anterior tibial translation - 1.45+0.6mm in SB group, 1.07 ± 0.8 mm in DB group [P value 0.1632(NS)]. All had a negative pivot shift test in DB group while two patients had positive pivot shift in SB group. MRI of operated knees showed that the values of mean sagital ACL graft-tibial angle and mean coronal ACL graft-tibial angle were comparable in both groups (P value >0.05 NS). Conclusions: There was no statistically significant difference concerning knee stability, knee scores, subjective evaluations & MRI evaluation of graft inclination angles between SB and DB ACL reconstruction groups at an average of 35 months of follow-up.
