Fig. 3From: Large lateral tibial slope and lateral-to-medial slope difference are risk factors for poorer clinical outcomes after posterolateral meniscus root tear repair in anterior cruciate ligament reconstructionIdentification of central sagittal plane on T1 MRI sagittal sequence. a The most proximal axial cut of the tibia was identified on MRI (right upper corner). Using this axial cut as scout image, the central sagittal plane was identified. b The sagittal longitudinal tibial axis was defined as the line connecting the centres of two circles, then a line is further drawn perpendicular to the longitudinal tibial axisBack to article page
