Arthroscopic double-bundle double-tunnel anterior cruciate ligament reconstruction using multi-strand hamstring autograft / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To explore surgical reconstruction and clinical effect of arthroscopic double-bundle double-tunnel reconstruction of anterior cruciate ligament (ACL) with multi-strand hamstring tendons autograft.@*METHODS@#Twenty-one patients (13 males and 8 females) with ACL deficiency were diagnosed with arthroscopy, with an average age of 25.4 (17 approximately 50) years. The 2 separate tibial tunnels and 2 femoral tunnels were drilled on the footprint of the ACL to reconstruct the anteromedial and posterolateral bundles with arthroscopy.Tendons were fixed with Endo-button/polyester tape constructs at the femoral side and with biodegradable interference screw at the tibial side.@*RESULTS@#All patients were followed up for 15.8 (13 approximately 23) months. The anterior drawer test was positive in all patients and Lachman test was positive in all but 2 preoperatively. The postoperative results of anterior drawer test were negative in all but 1 at 90 degree of knee flextion. Lachman test was positive in 1, suspiciously positive in 1 and negative in other patients. The Lysholm knee score increased from 36 approximately 58 preoperatively to 71 approximately 95 postoperatively and the fineness rate was 95.2%.@*CONCLUSION@#Arthroscopic double-bundle double-tunnel reconstruction ACL with multi-strand hamstring tendons autograft is effective and reliable to restore the better dynamic stability of the knee.
