The purpose of our educational exhibit is to: Evaluate magnetic resonance (MR) imaging findings of meniscal tears with meniscal fragments displaced. Show illustrative examples and schemes with a didactic approach.
MR Imaging–based d iagnosis of Meniscal Tears The prevalence of meniscal tears increases with age,
and meniscal tears are often associated with and contribute to degenerative joint disease.
Tears are more common in the posterior horn of the menisci,
particularly favoring the more constrained medial meniscus (MM).
in younger patients with an acute injury,
lateral meniscus (LM) tears are more common. MR imaging is a proved,
highly accurate modality for detection of meniscal injuries,...
Findings and procedure details
We reviewed 30 cases of displaced meniscal tears and found several types: Bucket-handletears: 10 cases. Anteriorlyflippedmeniscus: 5 cases Parrot-beaktears: 3 cases. Flaptearswithdisplacement: 7 cases Root tears and full-thicknessradialtearswithdisplacement: 5 cases Bucket- handle tears: The central fragment of a meniscus with a peripheral longitudinal tear may displace centrally into the intercondylar notch creating a bucket-handle tear.
The displaced fragment maintains anterior and...
MR imaging is the preferred imaging modality for evaluating meniscal pathology,
with high accuracy reported in most studies.
It allows accurate characterization of various tear patterns,
such as the previously discussed,
which can be instrumental for patient counseling and surgical planning.
