📌Fissure or Fissuring in Cartilage
- Fissuring is defined as a split or crack that is long and narrow.
- Chondral fissuring occurs primarily as a result of delamination between the obliquely and vertically oriented collagen fibrils, rather than by breakage of collagen fibrils.
- Chondral fissures that extend deep can propagate perpendicular to the bone.
- These lesions can be associated with reactive bone marrow edema, which highlights the lesion and aids in detection with MRI.
- Fissure with Chondral Flap: Chondral fissures may result in delamination of the cartilage and chondral flap lesions if there is an extension of the fissure parallel to the surface of the bone.
