[Tear_03] Longitudinal Meniscal Tear -01

Left drawing shows a typical longitudinal tear that divides the meniscus into inner and outer halves, and the right drawing shows the expected appearance of the tear.

Longitudinal tear with peripheral vertical orientation through the circumferential collagen fibers.

Longitudinal tears run perpendicular to the tibial plateau and parallel to the long axis of the meniscus.

Unlike horizontal or radial tears, this type of tear characteristically remains equidistant from the inner and outer margins and therefore should not involve the free edge.

These tears often occur in younger patients after significant knee trauma and have a propensity to involve the peripheral third of the meniscus and posterior horns.

These tears result from excessive axial loads that produce radial strain that exceeds the capacity of the radial tie fibers to resist plastic deformation.
