• Type of Tear: Longitudinal Tear
• Characteristics:
  • Runs perpendicular to the tibial plateau.
  • Runs parallel to the long axis of the meniscus.
  • This is commonly seen in younger patients following knee trauma.
  • There is a notable association between peripheral longitudinal tears and ACL tears. Specifically, 90% of Medial Meniscus (MM) and 83% of Lateral Meniscus (LM) peripheral longitudinal tears are accompanied by an ACL tear.
• MRI Findings:
  • Presence of a vertical line of increased signal intensity contacting the meniscus's superior, inferior, or both surfaces.
  • Does not involve the free edge of the meniscus, unlike horizontal or radial tears.
• Common Location:
  • Typically, it involves the posterior horn in both medial and lateral menisci.
