Abstract:

BACKGROUND: Arthroscopic reconstruction of anterior cruciate ligament (ACL) commonly adapted single-tunnel single-bundle or double-tunnel double-bundle methods. Though single-tunnel double-bundle has been used in the clinic, the curative effect remains unclear.  
OBJECTIVE: To compare the clinical results of ACL reconstruction using the single-tunnel double-bundle and single-tunnel single-bundle.  
METHODS: From March 2007 to June 2009, 39 patients with ACL rupture underwent arthroscopic single-tunnel double-bundle reconstruction (21 cases) or single-tunnel single-bundle reconstruction (18 cases). They both used anterior tibialis tendon allograft to reconstruct the ACL. Their clinical result was compared in terms of International Knee Documentation Committee (IKDC) and Lysholm scores.  
RESULTS AND CONCLUSION: The follow-up periods ranged from 12 to 25 months, mean (18.0±3.3) months, for the single-tunnel double-bundle group, and from 13 to 27 months, mean (19.8±3.6) months, for the single-tunnel single-bundle group. The Lysholm of the single-tunnel double-bundle group and single-tunnel single-bundle group were (87.0±2.18) and (87.5±2.33) scores, and the difference had no significant (P > 0.05). Since there are no significant differences between two groups in clinical outcome, the single-tunnel double-bundle ACL reconstruction is a reliable method for ACL reconstruction.
