Sorry to hear that Aidan....Also sorry to say that some cartilage/ligament injuries can take up to 6 months to properly heal. I know it's gonna be a tough one,looking at your bocks getting dusty in the corner, but you gotta rest your injured knee(s) a while before you work 'em too hard. You have youth on your side, for that you can be thankful because you'll heal a lot quicker than an ol' crumbly like me! My injury history is as follows(Been doing daft things for a while ok?)....
X2 slipped discs in my spine (Moving safes)
Broken left Clavicle (They don't mend,Bike accident)
Broken right Fibia and Tibia just above the ankle( Bike accident,Plate and 7 screws to fix it)
Broken Scaphoid in my right hand(Bike accident)
3 broken knuckles on my left hand(Skating accident,slammed into a wall full pelt while playing Roller hockey)
Ruptured Tendon in my right hand( Because bone graft from broken Scaphoid came loose)
More bumps,cuts, concussion and road rash than I can/care to remember.
This is just advice from an old fart who's known pain he'd not wish on anyone....Rest up mate.Let it get better before you take to the air again. Speedy recovery bud. Go easy eh?
