DonJoy Performance Bionic Fullstop ACL Knee Brace – 4 Points of Leverage Hinged Knee Support for Ligament Protection, Injuries, Prevent Knee Hyperextension for Football, Soccer, Lacrosse, Contact Sports

I’ve had this brace almost 10 years and has kept me very stable after 4 knee surgeries. The padding is finally starting to fall apart but I’ve used this thing for everything from sports to carrying patients as a nurse. I’ve been recommending this brace for years especially if you free from instability or buckling, and am about to purchase my second one!

I couldn't find anything specifically stating it helps a backwards hyperextended knee so I got this without knowing it helps. Turns out it does. The package was torn but it was intact. I sterilized it before using it. It arrived before the estimated date. I dont know how long it will last but so far it's working.

I really wanted this thing to be all it was cracked up to be.In shorts the Velcro straps cut my other leg, and the lower portion of the brace aggressively stabs into my calf when I’m walking.The brace is made of nice material and very heavy duty.The straps should all end on the left side (for left leg and right side for right) with the Velcro facing outwards, and the lower metal hinge should be heavily padded, not just shoved in a heavy duty sleeve.I really wanted this thing to be better than the McDavis but it’s not. It’s more comfortable if I’m laying down not doing anything, but that’s not why I bought it lol.

This brace is a lot. Provides a lot of support but not as much for routine walking type of exercise. Returned it as it was more than I needed. Good quality.

This is the best knee brace I’ve ever had. Great support, good materials, and comfortable. ACL surgery a couple of years ago, works for basketball.

These are way overpriced for the lack of quality. I'm pretty skeptical of the good reviews at this point. I've been using two of these for about 6 months now. I'm pretty disappointed with how quickly the straps degraded considering the price. The straps started to wear, twist, and loosen immediately and within weeks of buying the braces the whole system felt far less stable and supportive than it did out of the box. Now (as shown in photo) the top strap and stitching that holds the upper hinged bar in place has come unravelled completely and the bar is protruding into my leg. Both braces will need to be repaired. I'm pretty careful with my things, these braces should have lasted much longer for the price, i wouldn't pay $50 each for these knowing what I know now, much less the almost $300 they're asking for these things.

Almost a month now my knee feels great. I can even run up stairs skipping every other step again. Absolutely no complaints on this purchase.

Purchased to support interior left knee pain that is likely related to sprained MCL or tendinitis. Used for skiing 10 out of 12 days and it worked great. Offered great support and prevention of internal rotation or flexing. Did not inhibit skiing at all and support gave added and necessary confidence to the endeavor.
