| Horizontal Tear | Meniscal tear in horizontal plane, dissecting through circumferential collagen fibers. |
| MRI Appearance of Tear | Appears as a horizontally oriented line of increased intrameniscal signal extending to the superior or inferior surface of the meniscus, typically near the free edge. |
| Common Location | Most common within the posterior horn of the medial meniscus. |
| Characteristics of Tear | A pure horizontal cleavage tear extends only to the meniscal apex without superior or inferior articular surface disruption. |
| Parameniscal Cysts | Appear as lobulated lesions with increased signal adjacent to the meniscus. A high-signal-intensity fluid collection either directly overlying or adjacent to the meniscus. |
| Secondary Signs of Tear | Common secondary or indirect signs include parameniscal cyst, meniscal extrusion, and subchondral marrow edema. Horizontal cleavage or flap tears with horizontal components are often associated with meniscal cysts. |
