Short-term Follow-up of Double Bundle ACL Reconstruction using Autogenous Hamstring Tendons Fixed with Ligament Plate(R) / 대한정형외과학회잡지

ABSTRACT

PURPOSE: We wanted to evaluate the clinical outcomes at a minimum 1-year following anatomic double bundle ACL reconstruction with using autogenous hamstring tendons fixed with Ligament Plate(R). MATERIALS AND METHODS: We evaluated a total of 50 patients. Semitendinosus tendon was used for the reconstruction of the anteromedial bundle and the gracilis tendon was used for the reconstruction of the posterolateral bundle. For femoral fixation, we used an anteromedial bundle that was suspended in Ligament Plate(R) and a posterolateral bundle linked with Mersilene tape(R). For tibial fixation, we used double post-tie. The average follow-up period was 16.5 months. We analyzed the clinical and radiographic results. RESULTS: At the last follow-up, the Lysholm score was 92.4+/-6.8 points. For the IKDC score, there were 35 cases of grade A, 14 cases of grade B and 1 case of grade C. The Lachman test was negative for 40 cases, it was grade 1 for 9 cases and it was grade 2 for 1 case and the pivot shift test was negative for 45 cases and it was grade 1 for 5 cases. The side-to-side differences with the KT-2000 and the anterior drawer radiogram were 1.3+/-1.6 mm and 1.3+/-1.3 mm, respectively. The femoral tunnel enlarged to 1.7+/-0.6 mm in the anteromedial aspect and 1.6+/-0.7 mm in the posterolateral aspect, and the tibial tunnel enlarged to 1.2+/-0.4 mm in the anteromedial aspect and 1.4+/-0.5 mm in the posterolateral aspect. CONCLUSION: Anatomic ACL reconstruction using autogenous hamstring tendons that are fixed with Ligament Plate(R) showed good clinical results due to the strong strength of early fixation and the anatomic restoration of the ACL.
