  • Figure 3
    Sagittal plane image

    Sagittal plane image showing intrameniscal high signal intensity along the medial meniscus suggestive of meniscal contusion. Also note the flattening of the medial femoral condyle (arrows).

  • Figure 4
    Coronal plane image

    Coronal plane image of the knee showing that the ratio of the minimal meniscal width to the maximal tibial width exceeds 20%
