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

Figure 1 The absolute value of the degree of graft extrusion, measured as the horizontal distance from the most peripheral aspect of the graft to the edge of the tibia measured on the slice that the medial joint space is the narrowest on coronal and sagittal knee magnetic resonance imaging. A: Medial extrusion. a: The absolute value of medial extrusion; b: Meniscus remnant; c: Tendon graft; B: Anterior and posterior extrusiona. a: The absolute value of anterior extrusion; b: Tendon graft; c: Meniscus remnant; d: The absolute value of posterior extrusion; e: Tendon graft; f: Meniscus remnant.
