Abstract:

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is the key factor to determine repairing effect. Arthroscopic double-bundle hamstring tendons and single-bundle reconstruction of the ACL is a common repairing method in clinic.
OBJECTIVE: To compare the clinical outcomes of arthroscopic double-bundle hamstring tendons and single-bundle for the reconstruction of the ACL.
METHODS: A total of 55 cases with acute grade Ⅲ ACL from The Second Xiangya Hospital of Central South University between May 2005 and June 2009 were retrospectively analyzed, including 36 cases treated with single-bundle hamstring tendons reconstruction, 20 cases treated with double-bundle hamstring tendons and reconstruction. All patients received the same procedure performed by the same surgeon. All patients were followed up for 16-42 months, and the range of motion, stability, and other indicators were assessed.
RESULTS AND CONCLUSION: During follow-up, the range of motion of all patients was recovered without extension of knee joint. There was no significant difference in Lysholm-Tegner, IKDC knee comprehensive functional evaluation results, and KT-1000 detection (P > 0. 05). Patients underwent arthroscopy when removing the interference screw at one year after operation, and who had no significant reconstruction of ligament laxity. The clinical outcomes of ACL reconstruction with single-bundle and double-bundle hamstring tendons are similar.
