Brace
I shredded my knee a year ago and it is continuing to heal. I’m not sure it will ever heal completely. I ripped the kneecap right off sideways and everything that was holding it was torn. The knee literally went backwards 4 inches. That is the wrong direction to be going backwards! An orthopedic surgeon gave me this brace and it has been by far the best brace I’ve used. Due to the very high price, I have attempted to use at least 20 different styles of braces since. That has been a huge waste of time and money. And in the end, I lost my original brace on a trip. And I’ve ended up ordering two more of these $80 braces. The price is absolutely ridiculous and I feel taken advantage of by the price. But I love these braces. They make me feel more stable than any other others. I highly recommend this lightweight brace. It keeps my kneecap in the spot where it needs to be, and the height of the brace makes my leg feel much more stable. When my knee was at its worst in the beginning this was not nearly enough support by itself. I think I was on crutches for about nine months. The brace rolls up compactly for storage or travel. I washed this in the washing machine all of the time and hang it to dry.

CHANGED MY LIFE!!! PLEASE BUY THIS!!!!
WORTH THE READ ***KNEE DISLOCATIONS have to write this review solely on the fact that THIS KNEE BRACE CHANGED MY LIFE. I have had at least 6 dislocations of my left knee and probably 20 subluxations. I did competitive cheerleading and dance my entire life - and never gave my knee time to heal after each dislocation. (Wasn’t allowed to even if I tried.. ) because of this I have irreversible damage. After several different orthos looked at my knee the final say was that I need complete knee reconstruction surgery. That’s not an option at this point in my life- I have 2 toddlers to chase around and take care of being a stay at home mom and was told it is up to an 18 month recovery time before I have full use of my knee. My knee problems were honestly causing depression.. I couldn’t even chase my kids at the playground to play with them.. I would be hobbling behind my husband.. I tried every knee brace on the market.. I stumbled across this one and figured I had nothing else to lose. Not only do I have constant knee pain- but I also have ptsd and the flash backs of some traumatic knee injuries were debilitating on some what of a normal basis. When I first put this knee brace it freaked me out a bit.. I don’t like anything hugging my knee cap and your knee cap literally is snug in this little rubber web.. after a few minutes of walking around.. I actually started to sob.. happy tears. That might sound funny to some people but I have lived the past 26 years of my 30 years on earth walking on egg shells and the past 4.5 years of my life.. playing with my children with caution. THIS KNEE BRACE IS LIFE CHANGING. NOT ONLY CAN I RUN AND PLAY WITH MY CHILDREN BUT I HAVE NO PAIN WHILE WEARING IT!! PLEASE GIVE THIS A SHOT

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.

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!

Good Brace | Broke 1st Week | 4Get Post Sales Support
PROS: • Keeps the Kneecap in Place (better than other braces in my opinion) • Easy to Remove & Tighten - Only Four (4) Velcro Straps • Separate Cloth Sleeve Cover for knee/leg to aid in comfort (and to prevent slippage?) • Material - Rubber+Cloth Material. No Real Metal makes this brace pretty comfortable to wear. • Reputable Brand “DonJoy” = extensive line of durable medical products CONS: • BROKE within ONE (1) week of receipt & use the Rubber Webbing Broke (only slightly, but imho indicated more to come) • Materials = Non-Metal+Rubber = Not very good for Long Term durability • TOO MUCH MOVEMENT - Range of Motion - Non-Metal Joints on Each Side of Knee allow too much range of motion and not enough ‘sturdy’ structural support. • SLIPPAGE - Brace tends to Slip Up/Down during light movement (standing/walking) = Note: I was using a Size S/XS so smallest available size! • REPLACEMENT/REFUND “Process” Extensive (Frustrating)- MUST be Returned for either a Replacement or Refund (Photos, Multiple Emails, Printing Label, Repackaging+Arrange Pick-Up or Drop at Drop box) = seems a LOT for an item I received in just a white plastic envelope without any packaging material. After suffering a patella track issue, I purchased a DonJoy Web Knee Support brace. Initially, I loved this brace, but during the 1st week my brace webbing broke (see photos), which was very disappointing and speaks of its lack of long-term reliability. The brace webbing seems unique to this DonJoy product. I found that the webbing offers a unique amount of support that feels as if it is much more efficient at keeping One’s kneecap/patella in place compared to other braces. This brace also offers the same common support as other braces, with the two (2) joint supporting ‘struts’ {?- not sure of their proper name} on each side of the knee. However, unlike many other side supports, this brace’s side supports are NOT metal, but made of plastic. I felt that the plastic supports seem to bulge out sideways whenever I bent my knee, which I didn’t like. I think the brace would be much better if the supports were metal and better limited the overall motion of the knee. This brace also includes a slip over the leg/knee cloth nylon? sleeve, used to offer a bit of compression possibly (not enough to be uncomfortable or really qualify as compression), but definitely helps maintain the webbing portion’s location, so it does not slide up or down, both of which I experienced while wearing the brace. I found I would end up tightening the brace when sitting and my knee was bent, and then that this brace would slip up or down when I would stand or I actively moved (I walked, not like I was doing anything athletic). While this brace is good compared to others so far as a kneecap/patella track issue (kneecap popping out of track). I do not think I would recommend this brace if looking for general knee support or a brace to limit knee morion. Also, I believe it is extremely Important the sizing is correct, and I would go so far as to recommend that you contact a local prosthetic or durable medical equipment company to see if they sell this device and ask them to measure you in person for it. You can always take those measurements or the size they tell you and then order the brace here on Amazon or wherever. POST SALES SUPPORT Note: I would be more understanding of the extensive “process” if I were filing months later. My issue was within the 1st week! SELLER: (Via E-mail): When I contacted Motion Store, the Seller, I was told they would be happy to process a replacement. However, after multiple emails, my taking requested photos attached. I now have to send the brace back for them to even replace the device, ridiculous! So, do NOT count on post sales support without jumping through multiple hoops! Being down sick w/a cold+on one foot (I deep sprained my ankle so in a different DonJoy (MaxTrax foot boot). So, I decided I was done with the whole pain the bum situation at this point. But, if I return this product, it won’t be for a replacement. It will now be for a full refund (& I won’t buy another DonJoy product ever!) I will update later if I go forward with the refund “process”. MANUFACTURER: (Via Phone) Spoke to DonJoy the brace Manufacturer. For Replacement or Refund, expect to be required that You provide photos, wait for a Return Request to be processed and You MUST return the product, They will provide a shipping label for the return if approved. Tip/My opinion: This item is considered “Durable Medical Equipment (DME)” by Insurance Companies, and should be covered by most Health Ins.Co’s fully or at a percentage. It’s worth a shot to call and ask them before paying for it yourself. May need Your Primary Doctor to order for you, but would be Free! Plus, If thru a local distributor then any return/replacement would be a heck of a lot easier!!

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!

READ REVIEW UPDATE
I have severe arthritis in both knees, & nerve damage causing my right knee to collapse. I gave the brace five stars in every category, but the stability it provides depends on the cause of the problem with your knee. My orthodontist recommended the Don Joy brace three years ago, but told me because the knee’s instability was the result of nerve damage it would not prevent it from collapsing. When I don’t wear the brace, my knee collapses frequently, but less often when it’s on. I wear the Modvel knee brace/sleeve with the Don Joy brace instead of the thin nylon one that comes with the brace, & the two together improves my stability. The brace is the most comfortable of the five I’ve worn, & very flexible. When fitting the brace around your knee it’s important to make sure there’s no buckling in it, sitting or standing, on each side between the pins. This makes a difference in its support. The brace does reduce my pain/discomfort caused by arthritis, & so much so that I wear one on both knees. UPDATE: I wrote the above review in May 2022. I purchased it because of my satisfaction with the same Donjoy brace I received from an orthopedic surgeon at Scripps Clinic in 2018. Both are supposedly the same size, but I noticed immediately the length of the straps on the brace from Amazon were shorter. I thought they would probably stretch over time enabling more contact with the Velcro & secure fit. Unfortunately they didn’t, & the straps repeatedly come undone. This has not happened with the five-year-old, Donjoy brace I received at Scripps Clinic which continues to perform without any problems. The two-year-old brace from Amazon is now useless. The difference in fit & longevity between the two braces is so significant that I question the quality-control standards of the supposedly same model brace Donjoy sells on Amazon to the ones it sells to medical professionals.

Best brace out of 5 I have tried for this knee!
This product is beyond my expectations - I have a ruptured ACL, 3rd degree MCL tear, LCL sprain, bucket handle tear to the meniscus and bone contusions. The larger hinged immobilizer from the same company was not cutting it as I am small. My knee was still not being supported against torsional movements and I was limping badly, throwing off all my body mechanics. I decided to give this a try. With and without the sleeve it holds my knee securely - I have not hyperextended or rotated my knee since I started using it. I don’t feel any abnormal movements in the knee while walking with this, in fact, I tend to forget I am wearing it until I go to walk downtairs since it is snug. I don’t feel any pain, only slight twinges when using it, but my knee is a mess awaiting surgery. It is not listed as being recommended for combined instabilities or severe ligament injuries so I do caution that you make the choice with your doctor or Physio. I am very active and have leg muscles that are supporting my knee so that it barely feels unstable when assessed by the surgeons. Nobody suspected any ligament tears at all until the MRI was done, it was thought to be perhaps a minor MCL sprain and meniscus tear. I would compare this to strapping a bunch of silicone bungee cords on the outside of your knee to replace the damaged ligaments inside until they can be fixed. The Velcro issues in much earlier comments appear to have been resolved, this is very comfortable and strong.

Supportive knee brace, not too bulky - works well if sized and fitted correctly
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.
