I had ACL reconstruct about 6 weeks ago, I believe the brace I have is the CTi2(that's what the gym bag that came with it says...lol).  It's very comfortable, and not too bulky IMO-but I've also been wearing various knee braces for 12 years(that's when original injury was), so some might consider it bulky.  I've worn donjoy ones in the past, and like this one better.  The only thing I have noticed is if I don't put it on tight enough, it slides a little when I sweat.

I wish I found this site 6 months ago when I had surgery..  I tore my
acl had surgery in March(hamstring graff), I had 3 months of PT and
have been working out at the gym since.

Now I am looking into knee braces, I am thinking about the Donjoy
defiance or CTi2.  I play football, some softball and ski. Probably
more for skiing. I think I am leaning torward cti, but I want some
opinions... I have more friends that have the Donjoy. Any comments
would be appreciated.
