Hi, I ruptured my ACL playing football.
In my experience, and bare in mind everyone's pain threshold is different, but after the initial injury, i couldn't even stand let alone continue playing. With full motion very restricted from swelling. So that says to me it can't be a rupture. Maybe a tear but even still i'm assuming it would be very painful with you being unable to play.
I've read a lot that popping/cracking sounds coming from the knee, but not with much pain, is usually scar tissue being broken.
Maybe take it easy for the next 2 months until you play again. Everywhere I've read states- When working out on your knee; If it hurts stop, because you'll only hider yourself more.
Not a doctor my friend so take others advice to. Maybe ask for an MRI to be carried out so they can see exactly what's going on in there.
Rich.
