Abstract:
Objective To investigate the effect of single bundle anatomic reconstruction of the anterior cruciate ligament (ACL) with the hamstring autograft through anteromedial approach. Methods From January 2012 to Jan-uary 2014, 39 patients with ACL tore had been treated with single bundle anatomic ACL reconstruction with the hamstring autograft. In this group, 20 males and 19 females, 16 cases of the left knee and 23 cases of the right knee;including 27 cases of sports injuries, 5 cases of traffic accident injury and 7 cases of fall injury.8 cases were acute injury the others were old injury. 22 cases were had the meniscus injury. All patients were treated with single bundle anatomic ACL reconstruction with the hamstring autograft. The femoral tunnel was establish through the anteromedial approach. The medial meniscus suture was performed in 10 cases, partial resection in 2 cases, lateral meniscus su-ture in 9 cases, partial resection in 1 cases. The hamstring autograft was fixed with the RIGFIX system in the femoral tunnel and the BIOSURE SYNC in the tibia tunnel. The Lysholm score was used to evaluate the recovery of knee function, and the MRI score was used to evaluate the integraty of the grafts. Results All cases were followedup for 15 to 39 months with an average of 21.5 months. All cases had no vascular nerve injury, joint stiffness, infec-tion and other complications. All cases had good stability after 1 year and recover to normal sports after six months and intense sports after half past a year postoperation. The anterior drawer test and the Pivot shift tests were negative in all patients. The Lacheman test wasⅠin 1 patient and others were negative. The mean Lysholm score was (93.85± 4.33) which significantly increased compared with preoperative scores which was (36.84 ± 5.60) after 15 months (P <0.05). The MRI showed good maturity and normal morphology of the ACL autograft, the MRI score was (9.80 ±1.70) after 1 year postoperation. Conclusion The arthroscopic single bundle individual anatomic ACL reconstruction with hamstring autograft through anteromedial approach is effective, simple to perform and gives a graft the same as nor-mal anatomy. The grafts revascularization is good and effectively restore the stability of the knee.
