Post aclr return to flight duty mri came back with this: menisci: linear oblique truncation of the posterior inferior most aspect of the posterior horn medial menisci, consistent with a tear. what does this mean, is this a serious tear? no symptoms?

Probably not: Symptoms guide the treatment of inevitable tears in the meniscus, a cartilaginous pad between the two long bones of the leg. Nerves that sense joint angle, position in space, and trauma are in cartilage. If there is a tear that creates an otherwise harmless flap that catches or folds back with movement there can be an amplified sensation like joint lock-up. If it don't hurt, don't fix it
