Best brace I’ve ever worn
This brace right off the bat was super comfortable and lightweight. It immediately added stability to my leg and made me feel safe. I have a completely torn pcl ligament in my left knee and this knee brace was approved by my physical therapist for daily and sport activities. I am an active weight lifter and roller skater/skate boarder. Never have I had a problem with the brace slipping or moving around. Just make sure you readjust after a couple of hours to insure proper function, atleast that’s what I do. I’m not a huge fan of the compression sleeve because it’s so tight that it squishes all my leg fat and makes it bulge but I feel like it might help some people. So far I’ve had this knee brace for about 6 months and I think it’s time for a new one. I wear it almost everyday because I have no knee stability and cannot do any activity without it. The brace straps are coming apart and exposing some sort of plastic middle lining and the straps are becoming too long for the Velcro to reach an appropriate spot because of so much use. Other than that, I’ve always trusted the McDavid brand for all my sports Injuries and will always continue to do so. P.s. I added stickers to my brace to make it more fun :)

An exceptionally well designed brace but with some issue of the sleeve
Sized and worn as directed I've wanted to like this brace for helping me recover from a sports injury to my left MCL. Out of the box I find the design and quality of materials exceptional, and the fit as if it were tailor made for my leg. I quickly discovered no need to over tighten the straps as when worn with the sleeve it stays put even when I'm active. However, use of the accompanying compression sleeve on me has a tourniquet effect constructing the flow of soft tissue fluids in my calf; creating an edema of banding and bulging flesh. This suggests to me that although the brace is sized correctly the accompanying sized compression sleeve is not, and so sadly I've temporarily discontinued use of this otherwise spectacular knee brace. The one other point I will say is that the double hinges on this brace are sturdy and reliable, and align perfectly with my knee joint. No concern of wearing a hole in my outer garment. A limiting screw, if there were one, would serve this product well to guard against any momentary hyper extension of the knee. Finally, I will add that the open back design and thoughtful placement of the straps insures minimal discomfort or digging into the tendons behind the knee, provided of course that you refrain from unnecessary over tightening of the straps. Seems the trouble I've encountered with use of the accompanying size sleeve has to do with its elastic cuff. Use of a compression sleeve without that feature will likely not have the adverse tourniquet effect on me. I like the brace enough to purchase a differently designed sleeve from another manufacturer--one without the banded elastic cuffs.

Manufacturing Failure.
This is my second brace, I lost weight and had to go down a size. The first one lasted about 3 years with little issue, stretching straps. This one is falling apart. I don't know where they are manufactured now but the quality is lacking. Wish I trusted them enough to replace this one but I will be looking for another product from another manufacturer, to bad I liked the first one.

My new go-to knee brace
I am a 30 y/o male and I had my knees reconstructed twice in my freshman/sophomore years of high school. Needless to say, I have had quite a few knee braces over the years. I have a hereditary disorder where the knees are just getting worse each year. I still try to stay as active as I can while the knees hold out. This one is by far my favorite! I have been using them exclusively for almost a year and a half. Con: the only downside is I would not bring them hiking (mountain) personally. When I took them up quandary in Colorado (winter ascent) they slid down like all braces will and with all the other gear i had on I could not get to them to reposition them. End result was the hinge ended up below my knee adding extra resistance to each step and tiring me out a bit more. In the year and a half, this is the only time that this has happened. Pro: the sleeves keep thentypical smells at bay and make it easy to clean and wash. They can be worn with or without. I like the sleeve because it helps push out the low level of swelling I almost alway have. There is no material behind you knee. With most other braces, even the thickness of the neoprene forces your knee joint apart when fully flexed, thus straining the internal ligaments. For me, that is incredibly painful. This brace allows me to complete flex without pain. After with climbing issue, i was weary I would have similar issues skiing. I put one brace on and took the other off while skiing. Less then half way through the first day we returned so I could put the other brace on. The stability and control that this brace gave me was amazing. I would never go without it. 3 days and absolutely no pain. I am new and fell a lot! There was no slipping and sliding around and they dried out very quickly. After a long day of running or strenuous activity, I just put these on and it is like instant relief. Instead of days of pain, it feels like something has taken all the pressure off my joints. I typically will get a couple of pops (I just have that bad of knees) and they are better by the next day. These braces help proper alignment and tracking after the muscles and ligaments pull the joint out of wack. Walking up and down stairs is almost painless when they are on. Additional notes: I saw some complaints about the fit and comfort. You will have to spend some time to get it right. They come with little wedges that you place inside the brace to help it contour to you individual knee and leg. That is actually something I prefer. I wore them around the house for about 10-20 minutes playing with where the different pressures were. After about an hour I had both dialed in pretty well and have not touched the adjustments since. Now, I just put them on, sinch them down and go. 5 seconds and I can (and have) slept in them.

Nice packaging. I had both the 429 and 429x. This 4200 is definitely more rugged than those.

Ich habe viele getestet und diese ist die Einzige mit gutem Halt, da merkt man die wurde von Orthopäden entwickelt und nicht in China kopiert.. kaum Einschränkung beim Beugen aber guter lateraler Halt - Ich hatte Überdehnung des inneren Seitenbandes. Man muss allerdings die richtige Größe herausfinden und Achtung Links/ Rechts

Partendo dal fatto che ogni tutore fa quello che deve e che sta a chi lo indossa poi dover capire se l'articolo è fatto o meno per lui ad uno come me che ha subíto un distacco completo del LCL, trapianto di LCA ed LCP, ricostruzione menischi, ricostruzione capsula articolare e lacerazioni complete dei tendini questo tutore dovrebbe essere perfetto, invece io ritengo che provandolo anche solo in casa non basti per stabilizzare il mio ginocchio, anche perché come succede spesso nei trapianti di LCA/LCP mi è rimasto un discreto cassetto articolare che credevo potesse frenare questo bellissimo tutore. Nel mio caso direi che è più utile aimé qualcos'altro. Credo sia utile per chi lesiona o rompe il LCL/LCM più che per LCA/LCP. Ripeto che è un parere personale, nella vita sono un commerciante, non un medico!

Lieferung und Verpackung gut . Man muss darauf achten das man die richtige Seite bestellt , denn hier gibt es eine für das Linke Knie und eine für das Rechte Knie , die sind nicht austauschbar. Ich hatte Glück meine war für das Rechte Knie obwohl es nicht in der Beschreibung angegeben war ! Mein Knie ist wirklich so kaputt das demnächst eine Vollprothese ansteht und ich habe beim gehen auch richtig Schmerzen !! Legt man diese Knieorthese an kann man wirklich wieder fast ohne Schmerzen Laufen zumindestens bei mir! Ich habe schon viele Bandagen pobiert die Hier so angeboten werden und keine hat wirklich den ganzen Tag gehalten, dann waren die Schmerzen noch stärker da !! Das liegt daran das die meisten Bandagen zu stark Komprimieren , durch das Material zuviel Wärme entsteht , das Bein im Laufe des Tages immer dicker wird und dann geht irgendwann nix mehr. Wenn man bei dieser Knieorthese die richtige Größe wählt (es ist auch ein unterstrrumpf dabei) und sie anlegt hält sich die Kompression im Rahmen . Das komplette Kunststoff der Orthese ist innen gut ausgefüttert und es liegen vier Wiche Klettkeile dabei um die Orthese noch ein bißchen auf die eigene Knieform zu individualisieren . Dadurch und durch den Unterstrumpf drückt dann auch wenig bis nichts auch über den gesamten Arbeitstag. Die Orthese ist wirklich so stabil das Sie ein Überstrecken oder Verdrehen des Knies verhindert und das Knie wirklich spürbar entlastet so das selbst wie bei mir einer Grad IV Schädigung aller Knieteile ein Laufen wieder gut möglich ist bis zur OP !! Der Preis ist etwas höher als bei herkömmlichen Bandagen , meiner Meinung nach aber gut angelegt da Sie wirklich den Schmerz lindert da das Knie wirkungsvoll entlastet wird !!
