Proper femoral tunnel position is important for anatomical reconstruction of the anterior cruciate ligament (ACL). The purpose this study was to evaluate positions and tibial tunnels created using an accessory anteromedial portal technique in single bundle ACL reconstruction.The targeted at mid-portion bundles. We evaluated postoperative computed tomography scans 32 patients treated by a free-hand low technique. On side, Tsukada's method. 1) quadrant method, 2) Mochizuki's 3) 4) Takahashi's Tunnel obliquity also evaluated.The mean located 44.6%±2.5% from margin 48.0%±3.0% medial margin. center between posterolateral bundles: Quadrant 26.7%±2.7%/30.0%±2.9%; Watanabe's 37.7%±2.5%/26.6%±2.2%; 38.7%±2.7%; 21.8%±2.2%. 57.7°±6.2° sagittal plane 49.9°±5.6° coronal plane.In anatomic reconstruction, can restore accurate native footprint. Accurate facilitates recovery stability decreases graft failure rate.
