Comparative study of double-bundle anterior cruciate ligament reconstruction respectively with four and eight strands of hamstring tendons / 中华骨科杂志

ABSTRACT

Objective To compare the clinical results of two bundle anterior cruciate ligament(ACL) reconstruction respectively with four and eight strands of hamstring tendons. Methods 76 patients with chronic ACL rupture were randomized separated in two groups for two bundle ACL reconstruction. In the first group the semitendinous tendon was used to make two two-stranded grafts. In the second group the semitendinous tendon was used to make one four-stranded graft, and the gracilis tendon was used to make the other four-stranded graft. 33 patients in the four-strands group and 35 patients in the eight-strands group were followed up for more than one year. IKDC and Lysholm scales were used to evaluate the clinical results. Results In the four-stranded graft group, the side to side difference was
