Description

As part of our most stable line of sport performance bracing products, the DonJoy Performance BIONIC FULLSTOP ACL Knee Brace provides the ultimate in Anterior Cruciate Ligament (ACL) protection during recovery from injury, as well as prevention of future injury. FULLSTOP dampening hinges prevent hyperextension and help improve joint mechanics in both surgical and non- surgical knees. Through the dampening cycle of the hinge, muscle memory trains your body to keep both the braced and un-braced knees out of the "at risk" zone. Compression and thermal heat regulation technology in the brace keep you from overheating during exertion. Anti-migration technology prevents sleeve movement, even during your movement. The adjustable straps on the brace enable users to have greater customizability for a more secure, personal fit. The brace is also equipped with reflectivity for enhanced visibility in low-light conditions. The BIONIC FULLSTOP ACL Knee Brace is designed to treat and protect ACL and meniscus injuries, joint instabilities, moderate ligament and tendon sprains, hyperextension, and patella support. This brace is intended for use in sports similar to football, soccer, skiing/snowboarding, basketball, lacrosse, or volleyball. How to measure -1. Stand with your legs shoulder-width apart, legs slightly bent and leg muscles contracted. 2. Measure up six inches from the center of your knee with a tape measure.3. Measure the circumference of your thigh at the 6-inch mark. 4.Measure down six inches from the center of your knee with a tape measure. Then measure the circumference of your calf at the 6-inch mark

  • Don Joy always quality

My old brace is showing its age this is a good brace offers good support and comfortable to wear all day

  • Knee brace for golf that actually works
Size: Large Style: Knee Brace
I had injured my left knee and had to stop playing golf. I tried numerous knee braces that would support my knee during my golf swing without pain or further injury. This knee brace finally stabilized my knee allowing me to play golf again pain free without further knee injury. I have been wearing for several months to ensure I don’t re-injure or aggravate my knee. Very happy with this brace ... show more

  • It might work if you have skinny calves. But if you have muscle down there it’ll stab it.
Size: Large Style: Knee Brace
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. ... show more

  • Seems to be well made, but way too large.
Size: Large Style: Knee Brace
I had to return, as it was way too large, and I measured exactly as directed. It probably would have been fine if it fit correctly.

  • Great knee brace
Size: Large Style: Knee Brace
Great knee brace with good support. My son had lateral meniscus surgery and he likes the way it support the knee and keeps it from shifting and rolling during various activities. It’s a little expensive but probably the best non fitted knee brace on the market.

  • Measure your leg, don’t guess like all the bad reviewers!
Size: Large Style: Knee Brace
I read the directions which say, measure you leg., therefore I did (2X for good measure) I’m the exact size my measurements said I would be. Their fitment is clearly correct. My guess people think they wear a size small pant they, wear a small brace. Absolutely not. I wear a S/M pant, I’m 5’3 137lbs and I’m in a size large brace. Just for reference. I definitely noticed the feeling of stability while wearing. Although this will not stop all dislocations, it will get the major ones! I have a completely torn ACL with a meniscus tear and massive bruising of the tibia from an agressive dislocation. I can’t have surgery for 3/4 months and I have a busy schedule. I have used Don Joy in the past for my other knee (ACL reconstruction & meniscectomy) but it was a custom. Honestly I don’t feel a lot of difference in stability between the custom and this one. Obviously fit and finish but this is a quality piece for the price. Fits like a glove. I did adjust it about every hour. But that’s to be expected. I’ll reiterate, just measure your leg properly and don’t guess. You won’t have to worry about a return if you do that. ... show more

  • Go a size up!!!
Size: Large Style: Knee Brace
My measurements came out to Medium and it was tight on my calf. I returned for a Large, which fits better, but is still a bit tight. I'm pondering if I should have gotten XL for full comfort. The tricky thing with this brace is that it is hinges attached to a sleeve, so if the sleeve is too tight you have no way to loosen that aspect of it. But the knee hinge factor is excellent, and you'll immediate feel support and freedom when you have it on. In the very least, go one size up, if not two. If it wasn't for the sizing issues I'd give 5 stars. ... show more

  • If you are getting this for Ski/Snowboarding read this!!!
Size: Large Style: Knee Brace
I was 22 when I dislocated my knee and knee cap, torn all three ligaments in my knee. Never went to rehab or had a check up MRI. Fast forward 3 years later (I'm only 25) I dislocated my knee cap, but not the whole knee this time playing tennis. Probably getting minor tears and straining all the ligaments again. The problem this time was I was 19 days out before a snowboarding trip I had planned and already paid for to Steamboat Springs and they were getting dumped on all season!!!...... So I took the best care of my knee that I could for those 19 days but could not really afford to go to the doctor for them to tell me there is really nothing they could do anyways. I bought this brace as well as a compression sleeve. Day 1 had close to 2 feet of powder on the mountain so it was impossible to even just cruise down the mounting. Being a person who can't resist a good powder day decided to just let it go and shred! After Three days of just getting dumped on with multiple feet of snow and I rode every day from first chair to about 2. My knee was sore and tender but with the compression sleeve and this brace I was able to board knee deep POW and not miss any days on my trip. The only thing I felt this brace was missing is a little more stability, but I think they have a different brace that was designed to wear after injury where this one is designed for injury prevention. Either way if you read this whole review or just skip to the last sentence, this brace is well worth the money. ... show more
