By far the best knee brace I've tried.
Okay, so the material is a little weird. The sleeve that came with mine is not at all what was advertised, but it makes the knee brace slide down anyway, and isn't worth the trouble of using. The knee brace! It is FANTASTIC! It has a pretty low profile, it keeps my kneecap tracking properly and prevents subluxations/dislocations. Even though the side hinges are fairly flimsy-looking, they've helped keep my knees stable. My knees are in a very bad way, but wearing this brace spreads out the impact, keeps things stable, and makes me far more comfortable and safe. I love that it's reversible (that is, can be worn on either leg), because I haven't bought a second one yet. The biggest possible problem of wearing two is that they'll rub together, but that's a problem with all knee braces, and these ones don't seem like they'll detach each other, which is often what happens with Velcro. The Velcro is thick and strong, without being difficult to work with. Also, I read that these are contracted out to different companies and the quality can vary--I got the blue XL/XXL and I'm thrilled with it. Pointers: make sure you measure very carefully as the manufacturer clearly explains, and don't tug on the webbing part or it will wear out sooner. Oh, and a last thing--yes, there's fabric that goes around the back of the kneecap. It doesn't tug, it doesn't bunch, it doesn't hurt. It mainly seems there to keep the straps above and below in place, so they don't work into the back of your knee and make it uncomfortable, either. Great job, DonJoy! Thank you for helping me get some of my mobility back and easing the pain a bit!

Mosh Pit with a Torn Meniscus!
This brace is amazing, so much stabilization. Totally makes it possible for me to be active with a torn meniscus. Very easy to adjust to fit well and my knee joint is super supported. The on/off process is way better than the neoprene thing the doctor gave me. I survived a mosh pit with this thing aftera day of hiking and then ran around at the beach the next day— I would not have believed this was possible before. With this thing I feel like I can be active again without falling over in pain. I did have to put cushioned tape on one corner bc it was signing into my thigh a bit. This is prob bc I have heavier thighs than the athletes it was designed for. Minor addition fixed it though. Really thankful for this brace!

Very uncomfortable
I ordered this brace after having meniscus surgery on my knee 5 months ago. I was hoping it would provide support for me while trying to get back into activities like hiking, biking, and skiing. I measured my leg according to the instructions and ordered a size large. After the brace arrived, I tried it on with the compression sleeve. It was so tight that I could not wear it. I tried the brace without the sleeve and it fit ok. It has to be strapped on tight to work properly, which makes it less comfortable. I decided to try it on a mountain bike ride. I strapped it on and loaded my bike into my truck for a 15 minute drive to the trails. My leg was in pain by the time I arrived due to the brace. I rode around for about 2 minutes and the brace was very uncomfortable and did not perform as I was hoping. I took it off I think the problem is on the design. It seems like once the knee is flexed, it stretches the plastic until the knee is in the straight position. This does not allow partial flexion, which renders it useless for me and what I wanted to use it for. I ended up finding a better one made by 3m at my local cvs. I have worn it skiing multiple times and often forget it is there as it provides the support I want. I do not recommend this brace because in my opinion it is so uncomfortable that I do not want to wear it.

Relieves Pain caused from Patella Tracking Issues. Velcro strap wears quickly.
I play for a semi-pro ultimate frisbee team. On a typical week I'll play 15+ hours. I was recently diagnosed to have patella tracking issues in both of my knees. I already had a brace for my right knee and needed one for my left. This was much cheaper than the type I already had so I ordered this instead. The brace does its job and keeps my knee aligned while running, sprinting, jumping, lunging, etc. I like wearing the sleeve underneath as it reduced discomfort caused by the rubber material chaffing the skin. The webbing is pretty rugged. I put it through a lot, including landing/sliding on it frequently. The biggest down side of this brace is the velcro strap. I've had this brace for about 3 months and the strap is already showing significant signs of wear. The velcro does not stick very well anymore and the material has stretch out enough that its tough to keep it tight. Functionally the brace would work well again if this part was replaced, however, I can't find a way to buy just the strap. For the price it is a little disappointing that the strap is failing, but I have put it through a lot. The brace still works and I still use it but I have to readjust it every 15 minutes. The bottom line is, I like the brace enough that I would consider buying is again. The wear in the strap is annoying but I haven't had knee pain associated with patella tracking since I started using it.

Gives great knee support
I feel this brace gives my knee good support. It fits snug to my leg and is comfortable. It does not pinch and helps my leg relax. I would highly recommend.

Bought this on a recommendation from a friend who has the same brace. Daughter absolutely loves it for support while horseback riding for her torn ACL. Light and easy to adjust. Bought without the sleeve as she wears it over her leggings or her copper compression sleeve during basketball. Sizing is as shown in the chart. Her measurements matched fit perfectly.

We have used this knee brace brace extensively in the past, and this purchase is for the second knee, which now is also getting old! This item was delayed by some weeks, but the vendor contacted us to explain that their supplier was out of stock, so at least we were kept informed.
