Longitudinal meniscal tear
A longitudinal meniscal tear (sometimes called a vertical tear) is a morphological subtype of meniscal tear where a component of the tear is seen extending in vertical orientation parallel to the circumference of the meniscus.
They tend to occur in younger patients following significant knee trauma.
They are often always associated with a significant knee injuries (especially ACL tears).
- almost always involve the posterior horns (often peripheral 3rd 2)
They can be seen by the presence of a vertical line of increased T2/PD signal intensity contacting either the superior and/or inferior surfaces of the meniscus or both. Pure longitudinal tears spare the free edge of the meniscus.
