Can a meniscal tear heal by itself?
Most of the meniscus does not have its own blood supply, and so cannot always get the nutrients needed for self-repair. Whether or not the meniscus can heal therefore depends on where it becomes torn. Tears on the outer rim of the meniscus, which attaches to the knee capsule, do have the potential to heal because they are close to a blood supply. However, the more common site for meniscal tears is on the peripheral rim, or the inner aspect of the meniscus, and these have no capacity for self-repair.
