简要总结
Purpose: To find out whether the clinical and MRI findings two years after anterior cruciate ligament (ACL) reconstruction were associated with each other so that MRI-based graft invisibility in the anteromedial (AM) graft would have an impact on anteroposterior stability of the knee, and MRI-based posterolateral (PL) graft invisibility on rotational stability of the knee.
Methods: 75 patients. One experienced orthopaedic surgeon performed all double-bundle (DB) ACL reconstructions. Two independent examiners made the clinical examinations at the two-year follow-up: clinical examination of the knee, KT-1000, International Knee Documentation Committee (IKDC) and Lysholm knee evaluation scores and IKDC functional score. The MRI evaluations were made by two musculoskeletal radiologists separately and the means of these measurements were used.

结局指标
主要结局
The location of the ACL grafts in the insertion site in the femur and in the tibia reported as percentages
时间窗: 2 years after surgery
The measurements of the graft location from the MRI were made by two musculoskeletal radiologists separately and the means of these measurements were used. In brief, first the centers of the tunnels were measured from sagittal images referring to the Blumensaat's line and to the posterior femoral condyle. Then these were divided with the maximum diameters of the femoral condyle parallel to and perpendicular to the Blumensaat's line. In the tibial side, the centers of the tunnels were measured from the anterior edge of the tibial plateau and then divided with the maximum diameter of the plateau, which was measured from the sagittal view.
The visibility of the ACL grafts measured from the MRI
时间窗: 2 years after surgery
Two musculoskeletal radiologists made the interpretation of the images separately and the means of these measurements were used. A graft was considered visible when intact graft fibers were seen. The graft was considered partially visible when only few graft fibers were seen. The graft was considered invisible when no graft fibers were seen.
