Background Non‐anatomic tunnel placement, which leads to failure in double‐bundle anterior cruciate ligament ( ACL ), has focused greater attention on single‐bundle ACL reconstruction. However, single‐bundle ACL with 2‐ to 4‐strand autogenous hamstring tendon graft always showed weak graft strength. Methods To solve this problem, single‐bundle ACL with 6‐strand autogenous hamstring tendon graft was performed on 32 A sian patients in this study. At 24 months post‐operatively, all patients were evaluated with L ysholm knee scores, T egner activity level and KT ‐1000 examinations. Results The results demonstrated that no patients showed knee extension limitation. Of the 32 patients, there were 26 negative and 6 positive 1° in L achman test; 31 negative and 1 positive 1° in pivot‐shift test. There were four patients with a 5° flexion limitation. The median L ysholm score increased from 45 preoperatively to 92 post‐operatively ( P < 0.001). The median T egner sport level score increased from 1 preoperatively to 4 post‐operatively ( P < 0.001). KT ‐1000 examination revealed that the median anterior laxity at 25° of flexion was 6.3 mm preoperatively and 1.7 mm post‐operatively ( P < 0.001). Conclusions The data showed that arthroscopic central anatomic single‐bundle ACL reconstruction with 6‐strand autogenous hamstring tendon graft is a reliable method to restore stabilization and function of the knee.
