This disertation presents a comparative analysis of results after ALC reconstruction using two implant types for suspensory graft fixation in the femoral tunnel. Injury to the anterior cruciate ligament (ACL) of the knee is the most common ligament injury that requires operative treatment. Patient treatment can be non-operative and operative. So far, multiple ACL reconstruction techniques using a variety of graft types and implants that fixate the grafts have been described. Since 1995, titanium buttons with a loop have been used as implants for suspensory fixation of the graft in the femoral tunnel during ACL reconstruction. There are two types of titanium buttons in use: one with a fixed-length loop and the other with an intraoperative adjustable-length loop. The post-operative knee stability in this disertation was assessed 24 months after surgery using the Lachman test and the lateral pivot shift test, as well as the KT- 1000 arthrometer test. In patients whose graft was fixated us...ing a fixed-length loop implant, the mean post-surgery knee stability, measured with the KT-1000, was 1.27 +/-0.775; in patients whose graft was fixated using an adjustable-length loop implant, the mean value was 1.30+/-1.032 (P=0.691). The mean post-surgery IKDC score for the fixed-length loop group was 85.704 +/-7.792, while for the adjustable-length loop the score was 87.524 +/-6.7708 (P=0.233). The mean Lysholm score was 93.36+/-5.945 for the fixed-length loop group of patients and 92.68 +/-5.266 for the adjustable-length loop group (P=0.395). The mean Cincinnati score for the fixed-length loop group was 90.64 +/-7.030, while for the adjustable-length loop the score was 90.50 +/-8.906 (P=0.846). The mean Single leg hop test was 114.074+/-2.20 for the fixed-length loop and 113.094+/-2.192 for the adjustable length loop group (P=0.5). The results of this study lead to a conclusion that both types of implants can be used with success during ACL reconstruction, because the functional results of operative treatment of ACL reconstruction using both implants were identical after surgery.
