Abstract:

BACKGROUND: Our group has designed the arthroscopic anterior cruciate ligament (ACL) reconstruction using Femoral-Intrafix system in order to restore the rotary stability of knee joint and function of ACL. But its clinical efficacy has not been confirmed.

OBJECTIVE: To retrospectively evaluate the functional recovery of knee joint after reconstructed using single-tunnel single-bundle versus three-tunnel double-bundle with Femoral-Intrafix system.
METHODS: Clinical data of 60 patients with ACL injury from June 2013 to June 2015 were analyzed retrospectively. Hamstring tendon autografts were used for all patients. Among them, 30 patients received single-tunnel single-bundle reconstruction, the Endobutton was performed at the femoral site and the Milagro interference screw was used for tibial tunnels (control group); another 30 patients adopted three-tunnel double-bundle reconstruction with Femoral-Intrafix system, the Femoral Intrafix System was used to fix the graft at the femoral site, and the Milagro interference screws were used for tibial tunnels (trial group). The perioperative indexes were recorded. The anterior drawer test, Lachman test, pivot shift test, Lysholm and International Knee Documentation Committee scores at baseline and last follow-up were detected to evaluate the functional recovery of ACL.
RESULTS AND CONCLUSION: (1) All patients were followed up with an average of (25±4) and (28±3) months in the control and trial groups, respectively. (2) No patients had screw exfoliation, deep vein thrombosis, ligament rerupture or articular infection. (3) The range of motion of the knee joint was restored. The positive rates of anterior drawer test, Lachman test and pivot shift test in the two groups were significantly lower than those before reconstruction (P < 0.05), and the positive rates in the trial group were significantly lower than those in the control group (P < 0.05). (4) The Lysholm and International Knee Documentation Committee scores at last follow-up in the two groups were significantly improved compared with the baseline (P < 0.05), and the scores showed no significant differences between two groups (P > 0.05). (5) These results indicate that both of the two methods can obtain satisfactory short-term outcomes in anterior cruciate ligament reconstruction, and can improve the stability and movement of the knee joint. But the three-tunnel double-bundle with Femoral-Intrafix system can obtain better rotary stability of knee joint after reconstruction.
