Meniscus Tear MRI Correlation

Abstract

On MRI, the diagnostic criteria for a meniscus tear include increased signal contacting the articular surface of the meniscus or abnormal morphology. Bucket-handle tears are displaced longitudinal tears and may demonstrate a fragment in the notch, double PCL, double anterior horn, and truncated meniscal body on MRI. Longitudinal tears are usually traumatic, parallel to the circumference of the meniscus, and are often reparable. The displaced portions of horizontal flap tears may be easily missed on MRI and should be specifically sought in the medial recesses, the posterior intercondylar notch, and the popliteal hiatus.
