Abstract

Anterior cruciate ligament (ACL) is the most common surgically treated knee ligament. If we take into account the fact that incidence of ACL injuries is growing, it is clearly that the interest of orthopedic surgeons for this pathology is also growing. Increasing number of this operations leads to increasing of complications, which requires its analysis. One of the most common failure of ACL reconstruction is a bad position of the graft in the femoral condyle. This study aimed to analyze the positioning of the graft in to the femur by two generally accepted techniques--transtibial technique and technique through the antero-medial portal. The analysis included postoperative radiographs in 60 patients, of whom 30 were operated by transtibial technique and 30 by technique through anteromedial portal. Radiographic analysis involved the measurement of the AP digital imaging, the tunnel projection X ray measurements and measurements of the computed tomography (CT), which was here a control method. The accuracy of measurement was set at 0.5 degrees or 1 min. All radiographs were made in the same way according to the literature. The results showed that the neoligaments were placed lower in the femoral condyle by technique through anteromedial portal than by transtibial technique, and the difference was statistically significant (on tunnel X ray by anteromedial portal screws were average placed at 50.0 degrees and 10:20 am, and by transtibial technique at 37.5 degrees or 10:45 am). Based on the results, it was concluded that the neoligaments were positioned closer to its anatomical position by technique through anteromedial portal.
