Epidemiology
They tend to occur in younger patients following significant knee trauma.
Pathology
Subtypes
Associations
They are often associated with significant knee injuries, especially anterior cruciate ligament tears.
Location
- almost always involve the posterior horn, and most often the peripheral third 2
Radiographic features
MRI
Intramensical vertical line of increased T2/PD signal intensity contacting either the femoral and/or tibial surfaces of the meniscus. Pure vertical tears spare the free edge of the meniscus.
