Sturdiest most rigid brace of the lot

I was fitted for an over the counter Ossür cti today at Bonel medical in north Philly, they are unbelievable by the way. I've had trouble finding reliable reviews on these braces, while there are loads of reviews on breggs and don joy braces. I compared three braces while getting fitted, the cti, the bregg fusion and the donjoy defiance. The Bregg had some "give" to it's hinges, thinking like a much stronger neoprene knee sleeve. It's fit was extremely anatomical, and allowed for the best range of movement. It may be ideal for those looking for a knee brace while you're knee is still getting back to strength and size, so as to avoid getting another brace when you're muscles are built back up. The Donjoy was slightly stiffer than the bregg but still had a decent amount of give, and the hinges were in contact with the skin. The particular don joy didn't fit me that well, although for some it may be a great fit. Each brace had it's positives and negatives. The Ossur fit my knee like a glove, which is good, because due to the rigid frame of the CTI, the fit is nonnegotiable. This is the only pitfall of the CTI, that you're knee must be back in it's normal shape before you order one up, or else you will be stuck with a brace that is too loose or too tight when you're knee/quad is reshaping during rehab. Overall for me though it was perfect because more than anything, it really locks you knee in. A knee brace is no guarantee to prevent injury, and it's debatable whether they even protect from ACL re-tears, but I had two minor injuries since my acl tear because my leg wasn't quite as strong, I plan to wear this brace even when my leg is 100%, simply because it will just not allow the knee to bend a way it shouldn't due to it's ungiving frame. As long as you get one that will fit the longterm shape of your leg, this is the most sturdy, most protective brace for MCL, PCL, meniscus tears and in my case, it would've prevented a hairline tibial plateau fracture i suffered a few weeks ago when my knee buckled because it was still pretty weak. This brace is the best on the market in terms of quality, but is also the most particular. The Bregg fusion simply seems to make the knee maybe 30-40% more stable than it already is, where as this ossur is so bulletproof, there's no way you leg will buckle against the brace. NOTE; even in an ossur, you can still perform the mechanism that tears most ACL in non contact situations. I more so did this cuz it protects pretty much everything else.
