Predictive factors for coronal and sagittal graft extrusion length after using tendon autograft for medial meniscus reconstruction

Figure 2 Tunnel edge distance, measured as the horizontal distance from the intraarticular tunnel entrance to the edge of the tibia measured on the slice where the tunnel entrance is the widest on sagittal knee magnetic resonance imaging. A: Anterior tunnel edge distance (indicated by the letter “a”); B: Posterior tunnel edge distance (indicated by the letter “a”).
