Illustrations showing the effect of portal location on axial inclination and sagittal angulation. Representational images showing the effect of change in axial orientation (A) relative to a vertical line “V” and sagittal angulation (B) in relation to a horizontal line “H” on the femoral tunnel trajectories, with the two portals in knee hyperflexion. cFP, center of footprint of anterior cruciate ligament; FAM, far anteromedial portal; LFC, lateral femoral condyle; LM, lateral meniscus; MFC, medial femoral condyle; MIAM, modified inferior anteromedial portal; MM, medial meniscus; PT, patellar tendon
