Combines the BEST off-the-shelf knee brace in orthopedic history with FourcePoint Hinge Technology.
The DonJoy Armor knee brace with FourcePoint Hinge Technology is the brace to use if you are an extremely active individual or athlete who suffers from an ACL, MCL, or PCL instability or injury. Offering the same features as the standard Armor brace, this model is equipped with FourcePoint hinge technology – clinically proven to provide additional ACL protection by reducing the time spent near full extension (otherwise known as the “at risk” position).
The Armor brace is the strongest and most supportive brace you can get without a prescription. If you are concerned about protecting your ACL during sports or high impact activities, the Armor knee brace with FourcePoint Hinge Technology is the best brace for your needs.
This brace is ideal for anyone who plays football, skies, snowboards, rides motorcross, surfs, wakeboards, or participates in similar high impact sporting activities.
The DonJoy Armor knee brace is used to treat or prevent the following injuries:
Moderate to severe ACL or PCL instabilities
ACL/PCL combined instabilities (CI)
Recovery from ACL or PCL reconstructions
MCL or LCL instabilities
Product Features…and the benefits you’ll experience!
Available in ACL, PCL, and CI Versions You get to choose the brace that is right for your injury, which means your knee will get the proper support where you need it most.
FourcePoint Hinge Technology 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 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.
Custom Frame and Swiveling Strap Tabs Get a perfect fit by molding the brace to your knee, as well as enhance the fit and suspension of the brace with the swiveling strap tabs.
Aircraft Aluminum 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.

DonJoy Armor Knee Brace with FourcePoint Hinge reviews
My trainer recommended I wear this brace during football practice so I don't injure my ACL. I've taken a couple bad hits, but I haven't injured my knee and I think it's because of this brace. - Jason
I chose this brace after I hyper extended my knee at work. It is a very comfortable and functional brace. I sometimes can't even tell I'm wearing it. Great Knee Brace! - Frank

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. - The King of Court
I'm a professional basketball player and I've just recovered from a ACL strain in my left knee. This brace is amazing. I feel great on the court. And I feel like my old self. - NBA_BOUND
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. - Rockclimber girl
I used this brace after recovering from ACL surgery and found it to be a bit hefty at times, definitely wasn't the most comfortable braces I've worn. It did give me more confidence but I found myself constantly adjusting it trying to keep it from sliding down. - Kevin

Questions on DonJoy Armor Knee Brace with FourcePoint Hinge
From Mark Potenzone at 3/29/10 6:58 AM
We have a ForcePoint knee brace for my daughter and now we want to buy a Sports Cover for it because the straps are irritating her other leg.
How can I tell what size brace she has?
And is the Sports Cover the best thing to use for this?
The DonJoy Sports Brace Cover (http://www.betterbraces.com/donjoy-sports-brace-cover-10) is perfect for this purpose. It covers the knee brace to not only protect others during team sports, but also the unbraced leg. It also helps keep your knee warmer and it helps keep the hinges free from dirt and debris. You can see the sizing under the padding of your knee brace and you can also measure her leg and choose the right size from the sizing chart when ordering the sports brace cover.
From Al at 4/2/10 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.
From André at 5/22/10 5:48 PM
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.
From diane at 10/24/10 5:28 PM
strap number one does not fit tight on me. As a matter of fact, there is a gap between my leg (lateral) and the brace frame. The brace frame does not follow the shape of my leg. Will this present a problem for me? I have only used it around the house at this point to try and get use to it. and I'm concerned about it sliding down during heavier activity.
The DonJoy Armor Knee Brace with FourcePoint Hinge is malleable. Have you tried to bend the thigh cuffs to fit your leg?
If you advise your Order # I can have a replacement strap sent @ no charge.
From Todd Rovello at 11/30/10 7:29 AM
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.
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:
I just tore my ACL and MCL two weeks ago racing motocross, i am trying to postpone surgery for a year at least while the racing season comes to an end. I am basically looking for the best brace you have to support my knee and give it the best stability it needs to race motocross and do some cycling . I need the best stability for my knee to feel atble and not give way. Ive come across the donjoy armor extreme and now the donjoy armor with fource point hinge. Which would you guys recommend ?
We recommend the combination of the DonJoy Armor Knee Brace with Standard Hinge (http://www.betterbraces.com/donjoy-armor-knee-brace-83) and the DonJoy Impact Guard Knee And Shin Protector (http://www.betterbraces.com/donjoy-impact-guard-knee-and-shin-protector)
Let me know @ email@example.com if you have any other questions.
From Joseph Tuozzoli at 1/12/11 3:21 PM
Hello, Im 6'7" and have a history of severe lyme disease starting 8 years ago in which it has affected my ACL, PCL, MCL and LCL, mind you I have never torn anything, my ligaments are just worn out. Being my height, do I need something custom and if so which brace is right for me, I want to improve my skiing and get back into lacrosse but also relieve pain caused by my disease.
Whether or not you need a custom would depend on two things:
1) what do your leg measurements look like (thigh circ at 6 in above knee ctr, calf circ at 6 in below knee ctr, and circ right at knee ctr)
2) What activities do you plan on doing while wearing the brace?
If all you measurements fit into one size range and you’re aren’t doing high impact contact sports (Football, Hockey, Dirt bike, etc) then an Off The Shelf knee brace will be fine. Otherwise, a Custom Defiance would be a good idea.
From Sophie at 1/14/11 7:51 PM
I had my 2nd ACL reconstruction on my left knee last May and am looking to return to playing lacrosse and field hockey as well as take a skiing holiday. I do not play any contact sports. I tore my ACL both times playing field hockey so looking for a bit of support and reassurance. Due to the wide number of choices (from Donjoy alone!), I'm not sure what to choose, for example, why should I choose this brace over the Donjoy one that is specifcally for females? What is the main different between this new hinge and the older one? I did not injure my MCL or PCL but have a small sub-surface tear of the medial meniscus which my doctor did not consider serious and did not require any surgical treatment.
Both will address ACL.
Both have a Medial thigh swoop.
Both have a moldable frame for a custom fit
Both feature FourcePoint Hinge Technology.
Color - Armor is Grey. Female Fource is black and comes with a Custom Graphics Sticker Kit to personalize the brace to your own liking.
Impact resistance - Armor heavier and more resistant to impact, Female Fource is lighter
Length - Armor is Available in Standard and Short Calf lengths.

How much does the armor brace weigh?
From Earl M at 2/26/11 2:31 PM
I have been a user of ankle braces for two years now, I have read on some articles, however, that an ankle brace might also put strain on one's knees. I am now looking to buy a knee brace. Are the knee braces meant only for those who have already suffered knee injuries or can they be preventive/protective as well? What model do you recommend for someone who just wants to protect/limit his knee from injuries? If I wore a knee brace without having been injured, does that put more risk to me because of my dependence on a brace, which thereby weakens my knees and the surrounding muscles? Thanks!
There are a lot of elements to your question, so let's see if we can answer them all. Some ankle braces can put extra strain on your knees, but it depends on the nature of the ankle brace. If you are in a brace that limits the range of moition of your ankle then the extra force doese in fact have to go somewhere. However, the ankle brace would have to be very limiting in dorsi-flexion and/or plantar flexion to really cause injury to the knee. Most of our braces do not limit in those plains of movement much, if at all. Our braces are designed to limit Inversion and Eversion, which are moevements that your body normally restricts with your ligaments. However, when an injury occurs the ligaments stretch or partially tear and thus you need something to compensate for the lack of strength and support they gave you.
Our knee braces can be used for post-injury or injury prevention. If your knees are healthy and your activity levels are mild to moderate then I would recommend a Donjoy Playmaker Brace. If you do intense sports or extreme activities then we would have to go into more detail about those activities to recommend the proper brace for you.
there hasn't been any real definitive studies on the weakening of muscular tissue while wearing braces. Generally it's thought that a person loses some of their bio-feedback or proprioception while wearing a brace. And for this reason the general thought is that if you are only wearing a brace for injury prevention, then you should use it when you are doing activities that are high-risk. when involved in dynamic activities in which there are many variables (such as basketball, football, soccer, etc), a brace is a good idea. When in a controlled environment with less risk variables (such as jogging, lifting weights, daily life, etc) a brace would not be needed.
I hope this answers your questions.
From g at 3/3/11 11:19 PM
Could you please elaborate on the difference between Legend and Legend SE-4 versions.
The design and materials of the brace are exactly the same. The Legend comes with an extra set of brace liners and condyle pads, and the SE 4-point does not have those. The SE 4-point also has a two-tone color on the thigh to differentiate the two braces.
From Amy at 6/9/11 11:49 AM
My husband has a DonJoy brace and we are wondering it there is a lock position on it. He has re-injured his knee and we need the brace to stay in a locked, straight position.
I am a competitive high school soccer player. I recently tore my ACL and sprained the other ligaments in my knee. I am looking for a custom brace with the maximum level of protection for my ACL. Is thisa custom molded brace and if not which brace do you recommend?
No the Armor is our highest level of off the shelf knee brace. Our Defiance is the only custom brace we offer and is the highest level of protection.
From Michael at 6/22/11 6:30 AM
Is the FourcePoint Hinge brace a good canidate to use in watersports such as skiing?
The Fourcepoint hinge is used whenever there is a need or desire to hinder Hyper-Extension, protect the ACL, and Protect the Cartilage in the knee. The Armor and the Fullforce are very good braces for watersports, but maintenance will be key. Be sure to rinse your brace with fresh water after getting out of the pool, lake, or ocean. Dry the brace well, and then use dry teflon lubricant on the hinges. And Chamois liners are a good idea also because they will last longer with water activity. I hope this helps.
From Karen Mielke at 7/8/11 12:52 PM
My son is an offensive lineman (6'2" 265#) and we got these braces today. The medial condyle pad was very uncomfortable (painful) on both braces, such that he was sure the braces were too small, but he seems comfortable now that we replaced them with two of the included flat pads. Is that okay? The braces are snug, but otherwise seems to fit. He says they don't hurt but feel "stiff," which I'm guessing is to be expected.
Yes it is appropriate to change out the condyle pads to allow the brace to fit properly. Are the hinges stiff or just the overall fit?
From Namgo Chan at 7/19/11 2:55 AM
Hi I want to order this brace, short calf , I have measured my leg and my measurements fall between a medium and small. my thigh is a 17.5 which falls into a small and my knee is a 15"(still a bit swollen from surgery three weeks out of surgery, as my other knee normal is 14") which is a medium and my calf is a 14" which is just barely a medium. should I order small or medium? can I get a custom made? Should i order the defiance 3? I do need the fource point hinge is it available with the defiance 3? I am overseas right now but want to place this order so when I get back to the states on Aug 1st 2011 I have this brace, as I have to be back in China on the 20th, these Chinese braces just don't cut it." DONJOY please help" thanks sincerely Joe "OH" what is the ski version armor??
I would advise to order the Medium. You will regain the muscle back in your thigh area. Until then, if the thigh feels little big, you can simply squeeze down that thigh bar to fit, till you start to again the muscle back. We do, do specials on this brace and mix the thigh and calf sizes, but that has to be done directly through DonJoy and there is additional charge for that and the brace is not returnable. Since you just had surgery, your thigh will be slighly smaller than normal, but like i said it will regain it's size as you heal. You can do a Custom Defiance that is also another way to go. The ForcePoint hinge is available on both braces. With a custom brace you have to be measured by a special measuring device before the brace can be made. Ski armor is not really different than the short calf armor. I would just advise to go with a short calf armor with ForcePoint hinge.
From Chris at 7/30/11 12:08 PM
I would like to order my son the New Armor FourcePoint knee braces for protection during football, however I am not sure which size would fit best.
According to my measurements his Thigh is 23.5 Knee is 18.25 & Calf is 16
With a Thigh measurement exactly in the middle would it be best to get the large or XL considering his small calf? or should I get the one that fits knee best and try to adjust as needed?
Donjoy Armor tends to run small so I would recommend the XL.
From Joyce at 12/18/11 6:36 PM
I ski, nordic and alpine, snowmobile and wakeboard. With an ACL injury. I thought the Donjoy Armor knee brace with FourcePoint hinge would be the brace for me, but does it have the Medial Ski Deflector?
Yes, the Armor is the best choice brace for the activities you participate in. When ordering select the "Armor Ski" version, this is the version with the ski deflector.
If you have additional questions, please call 1-800-553-6019.
Have a nice day.
From Phil Ingram at 1/12/12 10:25 AM
I ride motocross and have both LCL and MCL injuries due to hyper-extension and straight legged impact. I am looking for the best support from re-injury but to also minimize discomfort when riding, running, etc. Will the fource point hinge be too restrictive when riding my bike?
The Armor with FP hinges would be recommended to prevent hyperextension. The lbs. of pressure can be adjusted for functional purposes. Should you have any questions give us a call at 888-405-3251.
From Abbas at 3/21/12 1:22 PM
I tore my ACL a couple of years ago playing soccer and never had a reconstructive surgery. I got to the point where I am running 3-4 miles and doing plyometrics after he injury. I played some flag football yesterday for the first time since injury and had no brace on. The knee felt good sprinting and cutting but I feel a little irritation in knee today. I am now trying to get back into soccer but still a little scared and nervous. What knee brace would you recommend for playing soccer and contact sports with a torn ACL?
Thanks in advance.
Donjoy Armor with FP Hinges for contact sports to protect the ACL.
From Ruben Ramirez at 5/11/12 4:19 PM
how can i get a diagram of how the straps go on my armor forcepoint knee brace its been awile since i used it thank you.
I am a cricket player but 5 year back i had an bike accident and my knee was injured. since then i can not run or put more pressure on my knee, even i cannot jump from 2ft height or climb stairs. which knee brace will useful for me.
What is your injury or diagnosis?
From matt at 6/6/12 10:34 AM
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.
Is this the best knee brace for our offensive linemen?
Outside of our custom made Defiance, yes. This brace is used by several D1 footbal programs.
From Aren at 2/11/13 6:46 PM
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?
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.
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!
From Antonio at 2/16/13 11:20 AM
I tored my acl and strained my mcl of my left knee. I bought a large don joy armor knee brace. I feel that the hinges ao pressing my knee, feeling a little tight. Should they run tight or more lose? Should i change them for an extra large size?
Hello, Antonio -
I would make sure that you have measured yourself correctly
1. circumference of center of knee
2. circumference of thigh 6" above knee center
3. circumference of calf, 6" below knee center
If you feel tightness in the hinge area, this may indicate that the brace is too small and you would need to go to the XL size.
If you have further questions, please feel to contact our product spealists at 888-405-3251.
Thank you and have a wonderful day!
From Nico at 3/19/13 11:32 AM
I tore my ACL while playing soccer and I'm looking for a good brace to start playing again when I'm done with PT.
1 - What's the difference between the DonJoy FullForce and the DonJoy Armor with FourPoint hinge?
2 – Can I exchange the brace to a different size if the one I get doesn’t fit well?
All of our braces have a 90 day return policy for any reason on betterbraces. Both braces have a year warranty, the Armor is the most rigid brace off the shelf. It is used by 21 of the 25 BCS football teams. It is used for contact sports such as footbal and soccer. The Armor is made from a stronger aircraft grade aluminum, as opposed to the FullForce. Those are the major differences.
