Purpose : To evaluate the diagnostic accuracy of magnetic resonance (MR) imaging in
the differentiation of meniscal tear patterns of the knee.
Materials and Methods : MR images of 93 patients with meniscal tear were included in
this study. On the basis of arthroscopic findings, the configuration of meniscal tears was
classified as horizontal (n=44), longitudinal(n=34), transverse (n=11), or oblique (n=5).
Oblique sagittal and coronal MR images were obtained and compared with the
arthroscopic findings.
Results : Among 94 cases of arthroscopically-proven meniscal tears, 35 of 44 horizontal
and 27 of 34 longitudinal configurations were correctly interpreted on MR images,
Sensitivity and specificity for horizontal configuration were 80% and 80%, respectively,
while the corresponding values for longitudinal configuration were 79% and 95%. On
MR images, two radial configurations were correctly interpreted form 11 confirmed tears
and only one oblique configuration from five confirmed tears.
Conclusion : MR imaging was useful for the differentiation of horizontal and longitudinal
tears, but inaccurate in cases involving radial or oblique tears.
