Type 5 Ramp Lesion involves two separate tears within the red-red zone of the meniscus.
Similar to the 4A subtype, the meniscocapsular and meniscotibial ligaments remain intact.
There are two parallel linear areas with high T2 fluid intensity signal, extending from the superior to the inferior articular surface within the red-red zone of the posterior horn and meniscocapsular attachments of the medial meniscus.
This tear pattern suggests an increased potential for instability.
Due to the presence of two separate tears within the red-red zone, mobility upon probing the posterior horn is significantly elevated, making it easier to diagnose arthroscopically.
However, repairing the meniscus with this tear pattern is more challenging due to the increased injured surface area involved.
