Longitudinal tears run perpendicular to the transverse axis of the meniscus, the opposite to the horizontal cleavage tear. They often lie in the peripheral vascular portion of the meniscus. They may therefore heal or be amenable to meniscal repair using sutures. Longitudinal tears have a strong association with ACL rupture. Careful examination is necessary as they can be difficult to detect.Characteristics include:

  • Traumatic
  • Can heal
  • 80% association with ACL tear



Occasionally longitudinal tears pass through the periphertal attachments of the lateral meniscus that surround the popliteus tendon. These are called fasicle or strut tears
