Fig. 1 Examples of meniscal damage on MRI with annotation. a) Vertical tear: Sagittal intermediate-weighted MRI of the knee shows a vertical tear of the posterior horn of the medial meniscus (arrow). b) Maceration: Coronal intermediate-weighted MRI of the left knee shows diminutive body of the lateral meniscus with partial maceration (arrow) and lateral extrusion. There is also a medial extrusion of medial meniscus (arrowhead). Large lateral and small medial femoral osteophytes are noted. There is a severe cartilage loss with denudation of the lateral tibial plateau which is also remodeled. c) Radial tear: Coronal fat-suppressed proton density-weighted MRI of the right knee (1) shows a small radial tear of the medial meniscus (arrow) with grade 1 sprain of the medial collateral ligament (arrowheads). Axial fat-suppressed proton density-weighted MRI (2) confirms the radial tear is located at the anterior horn and body junction of the medial meniscus (arrow). d) Horizontal tear: Sagittal fat-suppressed proton density-weighted MRI shows horizontal oblique tear of the posterior horn of the lateral meniscus (arrow). There is also a moderate Hoffa-synovitis (circle) shown as a hyperintensity signal at the intercondylar region. e) Root tear: Coronal intermediate-weighted MRI of the left knee shows a complete vertical tear of the posterior root of the medial meniscus (arrow) with medial meniscal subluxation (arrowhead).
