My surgeon informed me a year ago that it depends on the type and the pattern of the tear. There are at least three different scenarios...that I remember him telling me.My wife had a chuck removed, I don't think they do that much anymore, especially with elite athletes. They want that cushion from the menisucus.
Snipping off a protruding bit or flap is one of them. I remember that because mine was trying to fit that pattern. It still might.
