Objective To evaluate the feasibility of the anterior cruciate ligament (ACL) reconstruction with 6 strands of hamstring tendons enveloped by periosteum. Methods Between April 2008 and April 2009, 34 patients with ACL injury were treated, ACL of whom was reconstructed with 6 strands of hamstring tendons enveloping of periosteum and double Rigidfix fixation. There were 30 males and 4 females, aged 19-54 years with an average of 29.4 years. The causes of injury included sport in 19 cases, traffic accident in 8 cases, falling from height in 5 cases, and other in 2 cases. The locations were left knee in 19 cases and right knee in 15 cases. The disease duration was 3 weeks to 18 months (median, 9.4 months). The results of Lachman test and anterior drawer test were positive. The Lysholm knee score was 61.5 ± 3.6. MRI examination revealed ACL rupture in 26 cases and ACL injury in 8 cases. Results All incisions healed by first intention, and no early complication occurred. Twenty-eight cases were followed up 12-32 months (mean, 16.1 months). The result of Lachman test was negative at 12 months after operation; in all patients, knee extension reached 0°, and flexion reached 120-150° (mean, 132.5°). The AP and lateral X-ray films and MRI showed no bone tunnel expansion. At last follow-up the therapeutic effect evaluation was excellent in 25 cases, good in 1 case, and fair in 2 cases; the excellent and good rate was 92.9%. The postoperative Lysholm score was 91.0 ± 3.2, showing significant difference when compared with preoperative score (t=32.78, P=0.00).  Conclusion Six strands of hamstring tendons can ensure sufficient tensile strength, and use of the double Rigidfix absorbable screw makes fixation more reliable. Facing outside suture of periosteal flap can promote tendon-bone healing, so it is a good method of ACL reconstruction.
