MENISCAL OSSICLES: POSTERIOR HORN MENISCUS MENISCAL OSSICLES: WHAT ARE THEY Meniscal ossicles are areas of ossification that occur within the meniscus. WHY DO THEY OCCCUR Two possible causes are given: They are a Result of Post traumatic metaplasia and heterotopic ossification of a meniscal tear (either posterior horn or root). This is the most likely …

MENISCUS TEAR MRI KNEE WHAT TO LOOK FOR • In a Normal meniscus the superior and inferior halves should be symmetric. • In all three cases there is localised loss of ” volume” of the meniscus. • This gives the meniscus an asymmetric look. • Asymmetry in a meniscus is always abnormal and we need …

KNEE MRI MENISCUS EXTRUSIONS ARE POINTING YOU TO A ROOT TEAR THE MOST OBVIOUS CAUSE Loss of Joint Space from degeneration and cartilage loss is the most obvious cause. The reduction in joint space results in the meniscus being ” squeezed” out of the joint like toothpaste. BUT…there is another important cause to look for.. …
MENISCUS MACERATION DEGENERATION MRI KNEE WHAT ARE THE FINDINGS MENISCUS MACERATION DEGENERATION MRI KNEE Generalized increase in meniscal signal. Intermediate increase in signal on PD and PD/T2FS. The meniscus generally retains it’s shape but is ill defined. Due to the degeneration its more likely to tear and it also stops functioning like a normal …

MENISCAL INTRAMENISCAL CYST MRI RADIOLOGY DISCUSSION INTRAMENISCAL CYST. Extensive intra meniscal cyst anterior horn. A tear is not seen extending to the articular margin. However we may not always see the extension on MRI. So if you see an intra-meniscal or parameniscal cyst these are always due to an underlying tear even if we don’t …

VERTICAL MENISCUS MENISCAL TEAR MRI KNEE DISCUSSION VERTICAL (LONGITUDINAL) MENISCUS TEAR POSTERIOR HORN. The high signal extends to both the superior and inferior articular margins of the meniscus indicating a tear. It can be easy to overlook peripheral vertical tears as the torn outer fragment (Green arrows) can be very thin and may not …
POPLITEOMENISCAL FASICLES MRI TEAR NORMAL ANATOMY DISCUSSION These structures are the Popliteomeniscal Fascicles. They are the Antero Inferior Fascicle (Blue arrow). The Postero superior Fascicle (Pink arrow) which forms the, Popliteal Hiatus (Orange arrow) for the, Popliteus tendon (Green arrow) to pass through.

MENISCUS FIBRILLATION MRI LATERAL MENISCUS DISCUSSION This is NOT a tear. The anterior horn of the lateral meniscus as it approaches its insertion into the tibia is normally fibrillated like this and this is a normal finding.

MENISCUS FLAP TEAR MRI DISCUSSION MENISCUS FLAP TEAR MRI APPEARANCE Meniscus Flap tear MRI of the medial meniscus body. A meniscus flap tear is a horizontal tear through the body and the inferior portion has flipped out (Pink arrows) of the joint and lies in the recess between the superficial MCL (Green arrow) and …
MRI KNEE MENISCUS ROOT TEAR Each meniscus has an anterior and posterior root and there are four meniscal roots but we will focus on the Posterior root of the medial meniscus as this is the root most commonly torn. In this post look at the imaging anatomy of the medial meniscus root on MRI. WHAT …
