A Measurement methods in magnetic resonance imaging. (a) An axial view at the medial meniscus level. (b) The anteroposterior (AP) length of the medial meniscus is measured on sagittal-view images sectioning the midpoint between the medial edge of the tibia and the medial intercondylar eminence. (c) The mediolateral (ML) width of the medial meniscus is measured on the coronal-view images sectioning the midpoint of the AP width of the medial tibial plateau.
