I blew my whole knee 1 year ago. ACL + MCL + Meniscus (partial tears only though - no surgery). I didn't feel comfortable doing hardcore things for a roughly a year.
I started running again about 7 months later (6-8 kilometers). I wore a walmart brace for that, swelled up just a tiny bit. Nothing too bad. Then I got a real brace made with my measures, bla bla. Wore it once and tossed it in the closet lol. Needless to say, they suck.
The first few times I snowboarded this season I felt it. The day after, my knee would feel like it would be full of air kinda, I would just feel that urge to *crack* it. Once I cracked it I'd be good. Weird..
If I don't go rough with my knee I'm fine. If I get heavy impacts snowboard/skateboard, I feel it the next day.
I don't really care, I'm assuming it'll just got away someday as these things take a long time to heal.
***** REMEMBER!! Physio is pointless is you don't do your exercises at home. The recovery phase is CRUCIAL, do everything the doc says, no matter how redundant/tedious/boring it may be.
The doc told me that lots of ppl tear their knee ligaments and still manage to win gold medals. Don't worry.
Get well soon mate!
