Sorry, I wasn't clear enough. Yes, meniscus is cartilage, but it isn't articular cartilage--the kind that is smooth and lubricated by joint fluid and meant to be contacting the other joint surfaces. If you have a tear in articular cartilate somewhere else in the knee, that will require another method to deal with it, such as microfracture or O.A.T. S. which will extend recovery time.
