Anterior cruciate ligament (ACL) is acknowledged to consist of anteromedial (AMB) and posterolateral bundles (PLB). Endoscopic bi-socket ACL reconstruction using multiplied hamstring tendon autografts were performed in 13 patients (3 females, 10 males) since 2000. The mean age at the time of the operation was 28.7 years (range 12 to 48 years). The follow-up period ranged from 7 to 32 months.
This technique was reported by Rosenberg T. D., two femoral sockets were created through a single sockets of the tibia. ACL ruptures of 2 patients were caused by traffic accidents, and the others were caused by non-contacted force.
The knees were evaluated at the final follow-up using manual instability tests (Lachman test, pivot shift test), range of motion (ROM), side-to-side differences of anterior displacement of tibia with the KT-1000 knee arthrometer, JOA score, Lysholm score and IKDC (International Knee Documentation Committee) standard knee evaluation form.
In the postoperative results, the Lachman test was negative in 11 patients, and false-positive with firm end point in 2 patients. The pivot shift test was negative for all patients. The mean degree of knee extension was -0.2±0.8°, and that of knee flexion was 148.2±3.2°. The mean side-to-side differences of knee arthrometer values by manual maximum force was 0.2±1.8 mm. The mean JOA score was 88.2±10.5, Lysholm score was 95.2±5.3.According to IKDC score at the final follow-up, 6 patients were graded as A, 5 as B, 2 as C, and none of the patients were graded as D.
The results of this study show that bi-socket ACL reconstruction was a useful method, which obtained good outcome regarding knee stability in these cases.
