Assessment is typically performed on a single coronal magnetic resonance imaging (MRI) slice, but this method may miss the location of maximal circumferential displacement. We developed an extrusion mapping technique using radially oriented multiplanar reconstruction (rMPR) images from high\u2010resolution 3D MRI to enable circumferential meniscal position measurements perpendicular to the tibial margin. Extrusion was measured by three independent readers on rMPR images generated from non\u2010fat\u2010saturated 3D fast spin\u2010echo MRI in 20 patients stratified by meniscal tear and extrusion status. Intrareader and interreader measurement variabilities were assessed using intraclass correlation coefficient (ICC), 95% repeatability coefficient (RC; intrareader), and 95% reproducibility coefficient (RDC; interreader). Corresponding rMPR and standard 2D coronal midbody extrusion measurements were compared. Intrareader variability was low, with a mean within\u2010meniscus within\u2010angle standard deviation (SD) of 0.2\u2009mm and mean RC of 0.6\u2009mm. Interreader variability was also low, with a mean within\u2010meniscus within\u2010angle SD of 0.5\u2009mm and mean RDC of 1.4\u2009mm. At the midbody, there was 98% concordance for extrusion classification between rMPR and 2D coronal measurements within the interreader RDC (1.4\u2009mm). Exploratory regional analysis suggested different extrusion patterns between medial and lateral menisci and between torn and intact menisci. These findings suggest that circumferential meniscal extrusion mapping using rMPR images from 3D knee MRI is feasible, with low intrareader and interreader measurement variabilities. This framework enables regional characterization of meniscal displacement and should support future investigations of meniscus\u2013osteoarthritis relationships.<\/jats:p>\n
