๐ฆต Recognizing Flap Tears in Meniscus ๐ฆต
When dealing with meniscal flap tears, keep an eye out for a crucial indicator – a change in the slope of the meniscus's superior surface. This change signals a shift in the tear's direction, forming the characteristic flap.
๐ Changing Slope Sign:
Flap tears often exhibit a shifting slope in the meniscal surface, denoted as the "changing slope sign."
๐ธ Visual Aid:
For clarity, the corresponding axial image shows a free edge flap component (component not displaced). This component can also display a changing slope contour on its superior surface.
๐จ The Blunted Meniscus Rule:
As a general guideline, in cases without prior surgery, if you spot a blunted meniscus, it's essential to thoroughly search for any displaced fragments. Pay close attention to the intercondylar notch and recesses.
