Product Description

Features & Benefits:

Four-Points of Leverage Dynamic System
This patented technology was developed to reduce the strain on the ACL by distributing the load placed on the ligament via four points.Click here to learn how the Four-Points of Leverage works.
FourcePoint Hinge Technology (Stop kit not included)
Makes you less likely to suffer from an ACL injury because it reduces the amount of time your knee is in an “at risk position”, enhances the Four-Points of Leverage by increasing the posterior load applied by the brace on the tibia, and improves your natural gait by applying progressive resistance before reaching a firm end point during movement.
Adjustable Extension Resistance
The FourcePoint Hinge enables you to set the flexion angles (25˚, 35˚ (factory setting), 45˚, 55˚, or 65˚) based on your condition or point of recovery. This puts you in control where the degree of tension stops.
Available in Standard and Short Calf lengths (Ski/Snowboard Boot and Motocross Compatible)
Now you can choose the calf length to further customize the fit of your knee brace. The short calf length is recommend if you will be wearing ski boots or similar items at the same time as your knee brace.
Aircraft Aluminium Frame
You get the benefits of a lightweight and low profile knee brace that is also stronger, thicker, and more stable than the other lightweight knee braces on the market.
Anti-migration Supra Condyle Pad
Your knee brace will stay in place no matter how active you are.

    • I have the DonJoy knee brace on my left leg and wear it almost every day.
      I wear a sleeve under the brace that is changed daily. My question is
      'What is the recommended Cleaning Solution to use on the brace pads
      and cuffs and what is the frequency of cleaning?

      Thanks for the great product!

      Rick
    • Rick
      The best way to clean one of these braces is to clean the entire brace wil mild soap and water then let air dry. Do not remove the pads and liners because then you amy have trouble getting them back on in the proper place. It is up to you how often you feel you need to wash it.
  • James at 6/26/2015 5:09 PM
    • I had reconstruction on my ACL and Meniscus after a lacrosse accident, and my physical therapist highly recommends swimming to strengthen the muscles. I enjoy waterspouts in a lake setting, If I want to wear my already-owned Armor brace in the water is it built to work and last while being worn in the water?
    • Yes, you wont have any issues with wearing the DonJoy Armor Knee Brace in the water. Just remember to rinse with fresh clean water and let it air dry. You may need to lubricate the hinges from time to time if you do a lot of water activities in the brace, but you can use a dry teflon lubricant to keep the hinges moving fluidly.

    • I have a MCL injury and currently wear the playmaker brace. I was wondering if the armor brace would give a little more movement as far as for gardening and getting up and down.
    • Jennifer
      The Armor will provide with more protection than the Playmaker but because it is not a soft brace will not gather behingd the knee. It may be easier to bend than the Playmaker

    • I have recently sprained my MCL and need to continue playing the rest of my lacrosse season. I also suffer from knee hyperextension and patella tracking issues. Would the Armour brace be a good fit so that I can reduce pain and keep playing?
    • Maeve
      The Don Joy Armor Knee Brace with the Fourcepoint hinge would be the appropriate brace for you to wear to finish the season. The hinged brace will give the protectioin for the MCl, the fourcepoint hinge will help with the knee hyperextension and you will need to also purchase the Tru-Pull attachement and use this as well to keep the patella tracking normally. http://www.djoglobal.com/products/donjoy/tru-pull-advanced-attachment

  • victor at 6/6/2014 10:56 AM
    • Why this armor is not recommended for PCL lesions?
    • The Armor itself is okay for PCL injuries, as you can get PCL strapping. However, the fourcePoint hinge is contraindicated for PCL injuries. The fource point hinge will give resistance during the last portion of extension, which will increase force placed on the PCL to give protection to the ACL.

    • My son tore his ACL and strained his MCL. He had ACL surgery but he is complaining about is MCL not being supported with his knee brace. He is very active in sports, especially football. What brace do you recommend to help support his MCL?
    • Richard
      The Armor Knee Brace with the fource Point hinge is the perfect brace for your son. It will protect both ligaments and privid him support to prevent any further injury. The brace is made of a tough aluminum and is made for contact sports. The FourcePoint technology along with the Strapping system will protect the knee form re-tear of ACL . The bilateral hinges will give him support of the MCL.
  • Doug Sheppard at 1/26/2014 11:59 AM
    • I have been looking at this brace for a while as MRI's i have had indicate I have moderate to severe scarring on my MCL (Dr said that indicated numerous micro tears but never a complete rupture?) from previous hockey, skiing, and snowboarding injuries (mostly from hockey). I have delayed purchasing this brace as I have been looking for confirmation in previous questions that this will suit my purposes of daily wear to improve stability and also provide enough support when continuing those sports. My measurements are as follows:
      Thigh: 23 1/4
      Knee: 17
      Calf: 16 1/2
      Based on the above measurements I would assume a Large sized brace with short calf option would be what I am after? Would this be correct?
      Last question, do you ship to Canada?
    • Doug
      You are correct, you would need a large brace witha short thigh. We do not ship internationally. Here is the information on how to get az brace from DJO Canada

    • My son is a wrestler with a torn ACL but where he feels no pain and had wrestled with it in that condition for several weeks before getting it diagnosed. Because he would like to postpone surgery until after the season, we have been directed to investigate the DonJoy Armor Knee Brae with Fource Point hinge. Would this be appropriate for a wrestler?
    • Mary
      Thank you for contacting product support. I do not believe he would be able to wrestle with the Armor knee brace on. It is a rigid knee brace made of Aluminum and either would have to padded or would be banned from wearing it at all during competition. I would check with his coaches and see what is permissable to wear during competition. Most likely he would not be able to wear anything that an opponent could grab onto. If he could wear a soft hinged knee brace, I would suggest the Playmaker available here: http://www.betterbraces.com/donjoy-playmaker-ii-knee-brace-1, but this might not even be allowed.
  • Ivan at 11/5/2013 9:24 AM
    • Will the DonJoy Armor Knee Brace with FourcePoint Hinge provide support to the leg at the knee level when while walking your leg fails you and you tend to fall.
    • Ivan,
      The Armor with FourcePoint Hinge will provide support to the ACL/MCL/LCL. It will damper the extension of the leg when going into extension and decrease the amount of time the ACL is in the “at risk” position.
      You may want to look at the DonJoy Deluxe Hinged Knee Brace. This will offer you some compression as well and the hinged uprights for added stability.
      Thank you for your question and please contact us if you’d like any more information.

    • I have had an ACL reconstruction and my meniscus was really bad so after. They recommended this brace and now that I have had it for a lot less than a year and have been playing in it. The straps are started to stretch and the padding is starting to get ruff and come apart. I was wandering if there was some kind of warranty for that sense it hasn't been that long.
    • Hello Vanessa,

      Your Brace Frame has a 1 year warranty, the straps and pads have a 6 month warranty.

    • Hi,

      I injured my medial meniscus in HS and have reaggravated it on several occasions over the last decade. I injured it again last week playing hockey when I took impact to the outside go my leg. I would like a brace that could give me support playing a physical sport like hockey while still giving me range of movement. I have never been diagnosed with acl or mcl tears. What knee brace do you recommend?

      Thanks,
      Aren
    • Hello, Aren -

      The DonJoy Armor Knee Brace is the most highly recommended for high contact/collision activities such as hockey and football. Because you have medial meniscus injuries and no ACL or MCL involvement, you probably do not need this type of rigid frame brace. We would recommend the DonJoy Reaction as more of an appropriate choice.

      http://www.betterbraces.com/donjoy-reaction-knee-brace

      This would allow for minimal to no limitation in your range of motion and still provide appropriate support to your medial meniscus.

      If you have further questions, please feel free to contact our product specialists at 888-405-3251.

      Thank you and have a wonderful day!

    • Should this brace be able to handle sliding in baseball/softball? And also I ruptured my acl and I currently own this brace but was wondering if the fourcepoint hinges are good for this injury or should I disengage them so they act as a standard hinge? I wanted the fourcepoint so that after I have surgery which probably won't be until November, I could use it during my recovery as well.
    • The Armor with FP hinges would be the best product for your condition and activity level. The FP hinges are the only hinges clinically proven to protect the ACL specifically.

    • I am 3 weeks out of ACL reconstructive surgery, and researching which brace might be best for me. My MCL was torn as well. I lead an active lifestyle, but my main concerns are walking rough, uneven terrain for my job. I also participate in watersports, some snow skiing, and coach fastpitch softball. Contact sports are a thing of the past for me. Any advice would be appreciated.
    • Hello Todd,

      The Armor Knee Brace will definitely assist in the ACL recovery and support, as well as provide stability to the knee.

      If contact sports are not a concern, a DonJoy Legend SE-4 Knee Brace (http://www.betterbraces.com/donjoy-legend-se-4-knee-brace-41) may be preferable to an Armor as the armor is typically used for athlete level protection..

      If a rigid brace is not a requirement, we also have:

    • What's the difference between the standard and short calf lenght? Is it the same performance?
    • Standard calf: 16"
      Short calf: 14"
      (total length of brace)

      A shorter calf on the DonJoy Armor is recommended for shorter individuals (under 5'7) and patients who ski or ride motocross. The length of the brace has no effect on the functionality of the brace.
  • Al at 4/2/2010 1:35 PM
    • What's the difference between this brace and the regular Armor? I can't figure out why this one costs $50 more...
    • The difference is due to the fact that this brace comes equipped with FourcePoint hinges.

      The DonJoy FourcePoint Hinge is the only bracing technology clinically proven to protect the ACL. The FourcePoint Hinge enhances the DonJoy Four Points of Leverage system by damping knee joint extension, improving the brace's mechanical performance, and reducing knee shear forces. The FourcePoint Hinge utilizes a spring mechanism to apply a gradually increasing amount of resistance during knee extension. The resistance reduces the time spent near full extension, or in the at risk position, increases the posterior load applied by the brace on the tibia to prevent anterior tibial translation, and gives patients a more natural gait by applying progressive resistance before reaching a firm end point.

      The resistance can start at flexion angles between 25 and 65 and engages during the last 25 of extension prior to coming to a hard stop. Five different resistance levels are available to meet rehab protocol specifications and provide comfort. The resistance can be adjusted using the supplied allen wrench to modify the set screw placement. The same wrench can be used to turn the resistance completely off by simply flipping a switch.

      Clinical studies have also shown that the DonJoy FourcePoint Hinge increases knee flexion angles during the run-stop-jump task. Because the hamstring insertion angle increases and the quadriceps become mechanically disadvantaged as the knee becomes more flexed, anterior shear forces on the tibia and ACL strain are reduced. Therefore, athletes returning to sport after an ACL reconstruction who wear a DonJoy ACL brace equipped with FourcePoint Hinges can protect themselves while engaging in activities involving the run-stop-jump task.

Life changing!

Reviewed by:

For a 34 year old to have a knee as bad as mine could only mean I rode BMX. An ACL injury without insurance in 2005 meant that I walked on a bad knee until 2007 when I finally had surgery. The doctor said my knee looked like a 50 year old mans knee before surgery. My doctor performed the surgery and all went well but I never regained the confidence that I had before my injury. I got less and less active as the years went by and my knee got weaker and weaker.

I didn't have much hope for being active again and arthritis started setting in hard. Then I decided to order a DonJoy knee brace and everything changed. The moment I put it on for the first time I felt like I had never been injured. I could jump, and run, and ride my bike again. Almost ten years of not riding a bike, something that was a huge part of my life, I am back on my bike.

I can't begin to explain how much better I feel. I exercise again and I am not in pain. Heck I can walk without being in pain, that is amazing to me. I would highly recommend this knee brace to anyone with a knee injury. It is comfortable and very supportive. I wear it all day without issue. It fits under my pants and is barely noticeable. Do yourself a favor and get the best. I am a believer now.

I have been wearing this knee brace for a few weeks now. I began wearing it 6 weeks post ACL reconstruction. It is a comfortable knee brace that stays in place well. I recently wore it for a 10 hour work day and had forgotten that I had it on by the time I got home. I am wearing it for hiking and while working as a large animal veterinarian. It is definitely worth the money to protect my knee and to give me the confidence needed to work with cattle and horses.

My DonJoy FourcePoint Hing Brace enabled me to get my Black Belt

Reviewed by:
Quality
I recently received my Black Belt in both Hapkido and Taekwondo. I had a previous knee injury from playing football and re injured the same knee during training. I wore over the counter knee braces but was in constant fear of further injury. I adjusted my body mechanics to avoid pivoting on my "bad leg." As my Black Belt Review Board was approaching I realized that I had to be able to go all out. My Sports Dr suggested a DonJoy brace. I was concerned with it causing limited motion. The first day I wore it I completely forgot I had it on after a few minutes into class. It was like my knee had never been injured. I have had no limits to what i am able to do and because of this product successfully completed my Black Belt testing. DonJoy will get you back in the game! Thank you-

I've had this brace for about three months now after tearing my ACL playing basketball, and having surgery. This brace is so lightweight and comfortable that I sometimes forget I have it on. With it, I was able to complete a half marathon and get back to rock climbing, basketball, and snowboarding. I actually took a really bad fall snowboarding this year and was worried about if I reinjured myself, and the pain I was going to feel the next day, but it never came. This brace made sure my knee was never in a compromised position during my fall so I didn't get reinjured. With this brace I feel confident that I will get back to the way I was before I tore my ACL.

I just received my Donjoy Armour knee brace yesterday. I had ACL replacement on aug 18th. I've rehabbed hard and I started playing non competitive basketball in early December with over the counter knee braces. (I thought I was far behind schedule to playing again.) When I played ball last night with the Armour it was just like getting a new knee. The support was great and I was back to doing old moves again. Good Luck to all.
