ABSTRACT
Objective To evaluate and compare the clinical effects of forward and reverse anterior cruciate ligament (ACL) reconstruction through the arthroscopy. Methods From April 2008 to August 2009,97 cases with simple ACL injures were treated with eight strands of hamstring tendons in way of two-bundle and four-tunnel reconstruction. The patients were randomly divided into two groups according to the number of hospital admissions: odd numbers (A group, 47 cases) were treated with forward double-bundle reconstruction and even (B group,50 cases) were treated with reverse. The grafts were fixed with a suspension technique by mini-plates and mini-buttons. Mean follow-up exceeded one year. The function of knee joint were assessed by the IKDC, Lysholm and Tegner rating scale. Results Mean follow-up was 13.71 months.At the last follow-up, 2 patients in A group had a 10°extension deformity and 5 had a less than 15° flexion limitation. All patients in B group showed normal knee extension, and 4 had a 5° flexion limitation. According to Lachman test, there were one case with one plus positive and one with two plus positive in A group,and one with two plus in B. KT-1000 examination (30° flexion and 30 N) showed the side to side mean difference of anterior knee laxity was (1.04±1.11) mm in A group and (0.86±1.12)mm in B. According to objective IKDC evaluation, the results were graded as normal or nearly normal in 46 patients in A group and 48in B. There were no statistical differences in the IKDC, Lysholm, and Teguer scores between two groups.Conclusion Forward or reverse ACL double-bundle reconstruction with eight strands of hamstring tendons can both restore knee stability, and there is no significant deviation between the two techniques.
