Report Medical Waiver Question in General Military Helicopter Discussions Posted March 7, 2016 Nvm I misread that. If they correct your knee and it heals and is asymptomatic then you're good. But I'm willing to bet there will be a long recovery period. Yeah I read that as long as it heals properly after surgery you'll be fine. I just wasn't sure if it was basically up to the MEPs doctor or if you needed a waiver and it was decided by someone else.
