Fig. 7From: Transtibial versus independent femoral tunnel drilling techniques for anterior cruciate ligament reconstruction: evaluation of femoral aperture positioningMeta-analysis of aperture sagittal plane position. A Along BL measured on 3DCT by quadrant method (Higher percentage is defined as shallower aperture position). B Along DP axis measured on 3DCT by anatomic coordinate axis method (Higher percentage is defined as more distal aperture position). (c + m): combined conventional and modified TT groups. (AM + OI): combined AM and OI groupsBack to article page
