For the price this is excellent
I got an ACL injury. I work as a labourer in the construction sector, moving heavy objects most days. The Shock Doctor brace was my second choice after a German brand, however delivery times were unacceptable as I needed it urgently or I wouldn't be able to work. After 2 months of daily use for 10 hours a day, I can say it's borne the stress very well, is comfortable all day, provides very good support and it has allowed me to start healing my knee injury successfully. It's well made and has not deteriorated yet. It may not be the lowest profile however it fits under baggy work trousers just fine. The articulation is rigid enough but allows for movement without restriction or discomfort. The knee pad is very comfortable all day and keeps the knee straight to allow for recovery. I lift 30 kilo objects for hours a day and carry loads and my knee is able to cope. I recommend this knee brace especially for the price vs quality and features. I followed the advice on sizing and measurement and the brace fit very well. It does not restrict blood flow and does not overtly mark the skin. Well done Shock Doctor.

good knee support
this a great knee support which I bought to replace the one that the hospital gave me after I recovered from my accident at work 7 years ago in which I suffered a Tibial plateau fracture to my left knee, which is basically a crushed knee joint. this gives the same support to my knee as my old knee support which I was so glad about, it gives me full movement and I can walk for long distances with out pain. and helps keep the knee warm in the cold weather, as soon as I put it on the pain I may have had before putting it on goes which is so reassuring, the only thing I would suggest is that when you measure up for it go for the size up from what it suggest as the first one I ordered was a bit tight , and also you must measure 2" below the centre of your knee cap this is what I found out on the shock doctor web site. its quick to put on , just step into it and slid it up over your knee and centre it on your knee cap and adjust the bottom then the top strap so comfortable. also just to finish it is a high quality product and is well worth the price, its well made.

Good but ignore the sizing
I measured up carefully, watched the video etc. Measured again and ordered the Medium as I came in .5cm into the bottom of medium. While it fitted the knew nicely there is no way I could fasten the lower strap - I guess I have big calves! The thigh side strap I could just do up. So I returned the medium and ordered a large. This has been very good. The calf strap on me is about half way across. The thigh strap is nearly all the way across. If I want it done up tight for sport it is all the way across. It is bigger in the knee box, the medium was a better fit in that part of the brace. It has given a little with a few weeks wearing but the L still fits OK. So maybe if I had pulled the M so tight that I cut off my circulation fo a few days it might have been OK in the long run. Comfort wise, if you have ever worn any of the articulated neoprene braces you’ll know that comfort is a relative term. They are hot and sweaty (even if not using for sport) but if your knee is bad enough to need this type of support then this is a good one. Good level of support while recovering from a twisting injury that caused minor damage to ligament and cartilage.

Good value for money for limited support of PCL injuries
I have grade 2 injuries (serious) to the ACL and PCL on my left knee. I'm waiting for reconstructive surgery. The hospital supplied a Medi M.4s PCL Dynamic Brace (costing hundreds of pounds) which does a fantastic job of ensuring the tibia doesn't move backwards due to the torn PCL. A top product! Although the Medi brace is lightweight and relatively comfortable, it's still hard to wear 24/7. Also, after a while it affects the soft tissues where pressure is applied. I tried a simple, wrap-around neoprene knee support costing £15. As you'd expect it provided almost no forward support for the tibia. A waste of money for my needs. This Shock Doctor Ultra Knee Support (silly name) is pretty good. Obviously nowhere as effective as the Medi brace, but gives support and confidence for moderate walking. I'm too scared of making the damage worse to try anything more ambitious. Definitely better than nothing and can be worn under jeans all day. I needed to restart some kind of cardio exercises after several months away. I can't run right now, and don't enjoy cycling. So I've been wearing this in the pool (front crawl with no leg use). It works fine. It's well thought out and well made. Some reviewers said to go up a size. I measured 2" below the patella as 37cm and got the Large (35-37.5cm). It's very snug and I only just get it on and off, but I wouldn't want to go up a size.

Weird sizing and fit - doesn't offer the right support
Sadly it doesn't do exactly what it says on the tin. Despite the positive reviews and measuring beforehand I found this product to be a poor fit, loose at the calf, tight at the thigh. The adjustable straps do not fit the diameter of the support support sleeve. Costs too much to not offer the support needed

Gain medical advice first
I purchased the above brace after reading the reviews. I knew I had a acl issue and due to physical job was told a support would be advisable. The brace is comfortable very supportive, but when my knee collapsed in the brace the motion of the collapse against the ridgity of the brace has in fact ruptured my mcl lcl and pcl and completely ruptured the acl and meniscus to the point of none existence on scan I now need total recon surgery. My surgeon told me on seeing the brace said it is not a proper brace for the injury and it should have a movement and flexibility rather than the full ridgity which allows no range of motion. May be I have just been really unlucky but medically check fit for your purpose first

サポート感は抜群で、膝を曲げずとも歩行できるのですが 残念な事に、履くタイプで装脱着に苦労します。 Mueller(ミューラー) アジャスタブルヒンジニーブレイス 54557の方がお勧め。

装着感は良いのですが、汗をかいた後に外す・・・かなりきついです。幅があるので、長ズボンの下では無理、ハーフパンツでの着用がイイですね

Very useful, comfortable and adjustable brace for my Osteoarthritis Knee joint. Checks limited hyperextension. Helps to stay away from surgery.

très bon maintien de l'articulation, agréable a porter, facile a régler, légère, je m'en sert pour jouer au hockey sur glace suite a une rupture du ligament antérieur du genou. Je conseille très bon rapport qualité prix.

I feel really compelled to write this review because I don't like how so many reviewers say the sizing chart that Shock Doctor provides is incorrect. You can benefit from a mistake I made; I bought 2 but neglected to measure my left leg, assuming both my legs are the same size; I bought 2 XLs, but should have got an L for my left leg. If you are near to being one size or another-- GO DOWN, not up! I mean, assuming you aren't just buying them for aesthetics. First off, there is certainly a break-in period with these, as with anything that fits snug on our bodies-- forget the myth that only leather goods break-in. I have been wearing these everyday, for 10 days, for 8 to 10 hours everyday. They absolutely become more comfortable, and do need to be tightened up a bit more, as time goes on. So just because they feel too tight right out of the package, doesn't mean they will after a week. Second, you should realize that if you have big meaty calves (I envy you,) yes they will be tough to pull over your lower leg, but once you do, the lower straps on the braces are meant to tighten just above the muscle so that they *sit* in place. Hard to explain, but I hope you catch my drift. I have skinny little chicken legs, so I do have to pull them up now and then and re-tighten the straps, much more so with my left leg, again, because I got a size just slightly too big on that side. If you end up tightening the straps too far, you run out of velcro to connect with, and at that point you'll really regret getting a size too big. I found a work around for this, but it's not good to use them in a way they aren't designed to be used-- honestly, just by looking at these things and handling them, you can tell Shock Doctor put a lot of care into the design. ANYHOW, in terms of how they actually work.... like a charm. I have a genetic defect that makes my joints basically like rubber, so the danger of hyper-extending and spraining my knees is ever present. I noticed the difference in stability and support as soon as I put these on, they instantly made a very noticeable difference. I saw a reviewer on youtube saying it's like suddenly adding an extra layer of muscle.. yeah, sort of. More like adding integrity to connective tissue I'd say, but whatever. Awesome either way you look at it. The 3rd day I had them, I went walking around town for a good 3-4 hours-- amazed that my knees didn't feel utterly destroyed that night, as they usually would. My orthopedic specialist said I shouldn't have to wear them forever-- I didn't understand this until I tried them; you can indeed tell that they are training your proprioception via "bio feedback" or whatever. In the mornings now, I wake up with less knee pain, and actually feel more stable for an hour or so before I feel the need to put them on. I hope that stability period keeps growing to the point where I indeed won't need them-- though I will probably always wear them when I have to walk on ice or if I go on a technical hike (one day soon, god willing), just as a safety precaution to stop a sprains or a catastrophic hyper-extension. Oh, and having to wear them everyday, I finally washed them yesterday... hinges came out easily enough, hand washed in the sink, dried over night... just a necessary chore to keep in mind. I read you should really wash these sorts of things twice a week if you wear every day (which is kind of paradoxical when you think about it) even if you aren't getting sweaty. I have gotten in the habit of spritzing them inside with some isopropyl, before bed, hopefully that will keep them cleaner... otherwise, you do get itchy. Well, anyone who wears pads and such for sports knows what I am talking about... "athlete's foot" can happen anywhere on your body, so be careful of that. So, my only regret is buying one a size too big (and that would be only just an inch off maybe)-- so DO obey the manufacture's sizing guidelines, and DO measure both legs if needed, lol.
