A Current Review of the Meniscus Imaging: Proposition of a Useful Tool for Its Radiologic Analysis

Figure 13

Meniscal fragments from horizontal meniscal tears can sometimes be displaced in relation to the body of the meniscus, slipping above or below the rest of the meniscal surface. (a) Coronal T2 FSE Fat Sat MRI showing a displaced fragment of the medial meniscus; (b) a meniscal fragment (arrow) is seen posterior to the PCL in Sagittal T2 FSE Fat Sat MRI; (c) axial reconstruction showing meniscal fragment (arrow) on the T2-weighted fat-saturated sequence; (d) three-dimensional diagram showing the meniscal fragments; (e) arthroscopic views of a displaced tear of the medial meniscus in the intercondylar notch; (f) arthroscopic views of a displaced tear of the medial meniscus in the underlying posteromedial tibial plateau.
