단일 다발 전방 십자인대 재건술 후 대퇴골 터널의 위치와 대퇴골 터널 기울기의 상관관계

Purpose: The purpose of this study is to determine correlation between femoral tunnel angle in the coronal plane on a simple radiograph and femoral tunnel location in the sagittal plane on three-dimensional computed tomography (3D-CT). Materials and Methods: The subjects included 42 patients who underwent 3D-CT after the operation out of 70 cases of anterior cruciate ligament reconstruction using quadriceps tendon-patelllar bone autograft from April, 2009 to June, 2011. Measurement of the femoral tunnel angle was based on the anatomical axis of the femur in antero-posterior (AP) and Rosenberg views; femoral tunnel location was described as a proportional percentage on the medial surface of the lateral femoral condyle in the 3D-CT image; then the correlation between femoral tunnel angle and femoral tunnel location was analyzed retrospectively. Results: Femoral tunnel angle was 41.5°±6.8° (range: 29.7°?53.9°) on AP radiographs, and 34.9°±6.9° (range: 23.8°?46.5°) on Rosenberg views. The femoral tunnel was located 36.9%±11.3% from posterior, and 38.1%±6.5% from proximal on the 3D-CT image. On plain AP radiographs, femoral tunnel angle and femoral tunnel location showed negative correlation (p Conclusion: On AP radiographs and Rosenberg views, femoral tunnel angle showed significant correlation with the femoral tunnel location on the 3D-CT image, and the group who had femoral tunnel location in the anatomical range showed a relatively higher femoral tunnel angle.
