[Arthroscopic double-bundle double-tunnel anterior cruciate ligament reconstruction using multi-strand hamstring autograft].
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%.


CONCLUSIONS
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.
