Root avulsion: The meniscii are attached to bone (tibia) at two spots. If the posterior insertion becomes disrupted, the meniscus root is said to avulsed. This really men's the meniscus can no longer do its assigned job. Some meniscal root avulsions are repairable, and some just get debrided or smoothed out if surgery becomes indicated. If the meniscus is not attached to bone, it can become extruded.

Attachment to bone: The root of the meniscus is where it attaches to the bone. If the root of the meniscus is torn, the meniscus will not function properly. This can lead to osteoarthritis in the knee joint. If it is torn, surgery may be needed to reattach the meniscal root. You should follow up with an orthopedist to determine what is the best course of treatment is for you.
