Two things tear menisci 1) sudden violent loaded twisting can tear a healthy menicsus- don't fall! seriously- unless you are going to avoid skiing
, sports, wet grass these aren't something you plan.
If you have a torn acl, the knee moves more so fixing that may decrease your risk (controversial). 2) later in life the meniscus can wears out like a hose washer and come apart. Are less repairable.
