Will I be cleared by then? Please help!! Read plzz?

Well Ive had a knee injury (sprained acl, torn meniscus, bone growing problem) since November and cant do any activity since then. Its been quite a few months without cheering and PE. Im currently going to therapy 3 times a week. Cheer tryouts are at the beginning of April I believe. Will I be cleared by then?? Ive seriously cried over this because I love cheering and I want to do it my last year of middle school! :"( Help me and make me feel better :((
