I just got a knee injury from work and I'm bummin cause we're going to Hawaii for 15 days... Worst time to get a knee injury. We were kickboxing and It got twisted so I tried to just box and it buckled out from under me. We were filming at the time: http://www.demibarbito.com/knee.mov
The first thing I thought was "AAAHHHH, now I can't wakeborad".
I'm real aggressive with the recovery however.
Here's what I do (don't try this at home)
Ice right away.
Alternate ice and heat first few days after.
I alternate between 600 - 800mg of Motrin every four hours.
Rest the knee.
It's usually up to par within 1 - 2 weeks.
Everyone has their own way of doing things however.
