DonJoy Defiance® III Custom Knee Brace reviews

1. WOW! The pain is gone as soon as I put them on. When we decided to go to the braces, my doctor told me that many people don’t wear them because of the bulk and visibility. “They aren’t very effective when they sit on the shelf.” I am not finding it difficult to wear them since the inconvenience PALES in comparison to the pain relief when wearing them.” 2. What took me so long to agree to these? If only I knew then what I know now. I want to shout from the rooftop to all those people struggling with the decision to make the financial investment and to commit to the inconvenience. Count me in as a true believer! My only suggestions for improvement: Alter the design such that the brace can be removed without removing shoes and pants. Can both the bottom and top be on the same side? I travel frequently, the braces set off the metal detectors at the airport. Can they be constructed of another material that won’t do that? - Cindy
At first this hurt the inflamed side of my knee that the extra pressure was on. But now in about a week I have no pain at all when I wear it. The DonJoy Defiance is so light that exercise is very easy and it doesn't through me off balance at all. My only complaint is where to find pants that can be worn over it with it sticking out. I finally bought a couple of skirts because this definitely doesn't work under jeans. - cellogirl
I need my knee replaced, but want to wait till summer because of the length of time off. This brace has made it possible for me to walk, and walk pain free allowing me to have the surgery when I can afford to take the time off. I didn't realize how much I was throwing my hip out until I walked with this brace on. End of story...I can walk again and I have no pain . - bf
tore my acl and have been wearing ever since. Provides great knee support and I have more confidence that my knee will not give out. Some discomfort from the straps and material touching the skin on the inside of the brace, but no other complaints. - Cj
I wear two of them and they help greatly, won't be caught without them - willie
I am a gymnast and I tore my ACL and both meniscus on my left leg. 2 weeks after surgery i got the brace and it has been amazing! the support i got from the brace was incredible! the straps are a bit uncomfortable, but if you get the under-sleeve for it, it makes it alot more enjoyable to wear. Its been 7 months since the surgery, i am back to tumbling with the brace and i never think twice about doing a skill when i have the brace on. I love it!! - LaLa
I have struggled with knee pain and weakness since I was run over by a potato combine about 40 years ago. It finally got to a point where I needed some help. I thought that I would need to have a knee replacement surgery but I was a little afraid because I have heard some good and some bad things about that type of surgery. I wear the brace every other day now and it is amazing how good my knee feels. I did not have the surgery, at least not yet, I will put it off as long as I can. However, using the brace I can run, walk, exercise and do just about anything I want to try to do. I have not felt that weakness in my knee since I started wearing the brace. If I find that my knee hurts for whatever reason I put on the brace and the pain is gone almost instantly. The day I got the brace my wife and I went for a 2 mile walk. It was so nice to be able to walk with my lovely wife in the open air and not have pain for several days afterward. The DonJoy brace has been such a blessing in my life. At first the pressure on inside of my knee was annoying but the pain relief far outweighed the annoyance. The inner sleeve is a great option, I used it all the time at first but I don’t need to use it now. This is an awesome product thank you so much for your help. - Bill
tore my acl and put a crack in my tibia around april/march, had reconstructive surgery that july. After sitting out a whole six to seven months I "graduated" from therapy and recieved a defiance brace thanks to insurance;) now im still able to snowboard and even skate with a puck without worrying. long story short, get this brace to keep your knee stable. - jamar
I had MCL/ACL knee surgery back in 2004. I had this brace made for me and I used for the first 6 months after coming out of physical therapy. It allowed me to get straight back onto my snowboard and back into tennis without even thinking too hard about it. As my leg strengthened I stopped using it, and it went into storage for 8 years. Now my tennis is up many levels and I've started running very hard on-court, even skidding on concrete to change directions. Several times I've felt my knee come close to popping out again, and so I put my 8 year old knee brace back into action. It worked flawlessly as I felt my knee start to give way on a change of direction, and the brace took the entire force of my change of movement - I just kept on charging :-). You really can use this knee brace to the best of your abilities. - Sid
I tore my meniscus last year during training and my doctor said that the best thing to wear was the Donjoy Defiance III. I was excited because I see a lot of colleges and pro teams wearing them and they are suppose to be the best. When I got it it was the best thing I ever got. I wouldnt have traded it for anything else and i can be sure to say that it has faved my ass numerous times. Overall a great investment and I would recommend this product to any high-contact athlete who is look for protection - Frank
I really am starting to love my DonJoy Defiance Braces. I've had them for about 1 month now. I can walk a lot better than I have. Most times I can wear them for up to 5 hours then I really have to start to take them off. Sometimes I can wear them a little longer, but not by much though. They get aggravated and a little sore. I have to wear them on both knees. I have Osteoarthritis in both knees and need surgery as well in both. I was told that there's a good chance that I'll be wearing them for the rest of my life. UGH!! Oh well, anything to help me to get around. Thank you again DonJoy for giving me my knees back some. I agree with you all that it would be nice if there was a way to get them off/on without taking shoes and pants off as well. It's kinda embarrassing having to go into a small stall at work and do this every time I work there. The one Job I can MOST of the time wear them, but the other I have to take them off (work 8 hrs.) part way through working. - TippyToes
Old Soldier
Back in 1999 I tore my ACL, PCL, MCL, and Meniscus if an Airborne operation. After the surgery was complete, I was fitted for an older model of this brace. I used it for 12 years before it finally failed broke. Quite honestly, I nearly paniced. Despite the road blocks put in my path by the VA I finally got a new brace, the Defiance III. WOW! This is what comfort should be. After almost a year without a brace, it sure feels good to be back in action. Excellent product. - Old Soldier
I tore my left ACL and was given this brace to play basketball in post surgery. At first the brace rubbed and left skin irritated but was easily broken into. I don't even notice that I'm wearing a brace, it is that confortable. The only downside to this brace is it squeaks loudly like it needs oiled. Also, the plastic that holds the straps came loose and it pops in and out when I run. Other than those downsides, it's a great brace. - Em
Shelbi Kelly
The DonJoy Defiance Knee Brace is meant to support and protect the knee, but primarily and specifically the ACL. Athletes will rely and depend on a brace such as the DonJoy Defiance Knee Brace after suffering from a large injury that generally resulted in a reconstruction surgery. I, myself suffered a detrimental injury to my knee, I was looking for the best quality brace in which I could rely on while slowing going back into sports, specifically soccer. The brace begins halfway up my shin and ends near the middle of my quad. In the brace I feel confident going into slide tackles and simple things such as sprinting and pivoting/cutting, even after nearly a year of rehabbing my knee post reconstruction surgery. The brace, although said to have been measured just for me leg, seems too big at times and never generally stays in one place. Running in the brace feels unnatural and appears to weigh me down. I don’t receive full range of motion in the brace and it appears a bit bulky at time. Although I have discovered things I’m not so thrilled about with the brace, I’m very thankful for it. With the guarantee that you will not re-injure the ACL, I feel beyond secure and safe. Definitely recommend it to any young athlete, or any athlete in fact, who is interested in playing at a high level of play after suffering from a serious knee injury. - Shelbi Kelly

  • From Zach at 9/18/10 1:44 PM
    • I am a Wide Receiver and Outfielder who has had 2 acl reconstructions on my right knee, I was curious as to what brace you think would be best for me? I am looking for a light weight brace that will give me maximum stability and protection of my acl, while not sacrificing any speed. I guess I have narrowed it down to either the Full Force or the Custom Defiance (unless you recommend something else), but I'm curious as to how much the Defiance weighs. Also another concern is I am 7 months post op, so I am just now starting to lift heavy in my legs again, because of this I'm concerned about outgrowing the brace. Would gains from weight lifting be enough to cause a need for a change in size in the braces that are not custom fitted, based on the intervals of measurement and sizing? With all this being said please let me know what you recommend. Lastly, I was wondering if there is any location near Charlotte, NC that I could actually go and try these on and see for myself. Please let me know! Thanks,

    • Hello Zach,

      The Defiance weighs approx 20 ounces, while the Full Force weighs 22 ounces.

      The Defiance can be remade to new measurements within 4 months of the brace's manufacture date, after that it can be remade at a lower price.

      At this time we are a retail website only, with no physical retail location.

    • I have the townsend full shell knee brace. The problem is that the brace slides down when ever i run with it in football and its to heavy. Would DonJoy Defiance III Custom Knee Brace be better instead of the Townsend Full shell knee brace?
    • The DonJoy Defiance III Custom Knee Brace will fit better than any off the shelf brace due to the fact that the brace will be custom built for your leg contours.

    • Yes you may use the Donjoy Defiance III in water just rinse it with fresh water after each use and air dry. You may use dry Teflon lubricant to prevent hinge wear and tear such as Triflow or White Lightening.
  • From Tammy at 4/18/11 2:05 PM
    • Does this brace need to be worn underneath clothing? Or can it be worn over jeans or any other type of pants?
    • It should be worn under clothing if possible. Obviously you will not be able to wear it under tight jeans, so wear it over the jeans in that case.
  • From Kyle at 6/2/11 10:37 PM
    • I have just had my 4th acl surgery. I am 16 years old and love sports and never see myself quiting. I have had 3 surgeries on my left knee including the one I had 6 weeks ago. My other knee braces don't help me because my left knee is very loose and my tibia slides to the inside very easily and a lot. Can your knee braces help to make that stop? The other surgery I had on my left knee made my knee do the same thing that I just explained and I did just as I was told in physical theapy and by my doctor who is ranked in the top 10 surgens in Ohio. If the donjoy knee brace can't help me then there is no other brace that can help me. I know this because I have tried on every brace imaginable.My sporting career is on the line. Can the donjoy knee brace stop the movement of my tibia?
    • The best Donjoy Knee Brace for your condition is the Custom Defiance ACL Brace with Fourcepoint Hinges. The frame design combined with the only hinge clinically proven to protect the ACL would be your best choice. In saying that, it is part of the equation. The surgery, therapy, your compliance in applying the brace properly and wearing it at all times is important. It sounds like you've had a long history of injuries so this is something you should discuss with your surgeon and family. However, to answer your question, this would be your best choice.
  • From andrew at 8/15/11 4:49 PM
    • How do you clean or wash the defiance III knee brace?
    • Keep soft goods attached and hand wash with mild detergent and air dry. Some patients will just wear it in the shower or dunk it in a soapy water tub and a fresh water tub after each use.
  • From Dorothy Stevens at 8/18/11 8:40 AM
    • I have a donjoy custom made brace from about 10 yrs ago. Its been great but the velcro and straps are worn. Can i get it refurbished and how would i do this?
    • Yes just call us at 800-553-6019. Your brace number will be helpful when ordering your replacement parts, if you don't know where it is on your brace, we will help you find it, or look up your records with your name.
  • From Laurie at 8/27/11 9:02 AM
    • Is the knee brace waterproof?
    • It's ok to take in the water. Just make sure you rinse the hinges and softgoods out with fresh water, let it dry, and re-lubricate with a teflon dry lubricant. Usually a bicycle chain lubricant will work.
  • From Paul lafontaine at 10/9/11 4:52 PM
    • Will the cust Defiance be able to be used for skiing and hockey stabilities? I need for both and have had 2 meniscus surgeries.
    • Yes the Custom Defiance can be used for skiing and hockey.
  • From Zinn at 10/17/11 1:53 AM
    • Hi.
      I live in Dubai, UAE and I have had 2 ACL Surgeries so far. Also, I have recently torn and reconstructed my MCL. Some of the meniscus has also been removed.

      What knee brace do you recommend for me? I am a grappler/wrestler.

      I understand that for the Defiance III, there are measurements taken. Since I live abroad, who will take the measurements?


    • Hi Zinn,

      I have asked out international department to contact you about ordering a Defiance III. Someone will be contacting you shortly.

      Have a nice day.
  • From Chris at 11/2/11 2:02 PM
    • Hi,
      I've used both the CTi and DJ Full Force knee brace. I like the way the DJ brace upper attachement grabs the top of the tibia and I find that it doesn't slide down as much as the CTI. However during kitesurfing I want a brace that is very stiff laterally and I find the stiffness of the CTI to be superior to the Full Force though. How would the lateral support of the Defiance compare to a CTI and a Full Force brace?

      And would a short calf be less prone to migration as it would have both straps above the bulk of the calf muscle? How does the support and stiffness vary with the calf length option?
    • Hi Chris,

      The Defiance is made of carbon fiber and it the stiffest brace we have. We have an additional order option to reinforce the brace with another layer of carbon fiber if you want. The reinforced frame is an option we market to our collegiant and professional football players as well as otehr high contact or extreme sports athletes. The Defiance also has our 4-points-of-leverage system, which helps with fit and suspention. But, most importantly it help prevents anterior tibial translation, which can injure the ACL. Depending on you calf shape and size, the short calf may be helpful to prevent migration. The shorter calf length will not comprmise the stiffness of the brace.

      Another option for an off the shelf brace is our Armor. It is made of aircraft grade aluminum and is our strongest off the shelf brace.

      If you have additional questions, please call, 1-800-553-6019

      Have a great day.

    • How do you wear soccer shin guards with one of these knee braces?
    • The brace comes in two differnt calf lengths. If you are concerned with shin guard clearance, I suggest ordering the "short calf" version.

  • From MacKenzie at 4/16/12 9:28 PM
    • After i hit the gym to build my leg muscles back up, will the brace still fit me or will i have to get a new one?
    • Hi MacKenzie,

      All custom knee braces have a 4 month remake window. if your leg size changes within the first four months of receiving the brace it can be remade one time at no charge

      Have a nice day.

  • From Natasha at 6/10/12 5:45 AM
    • Does insurance help pay for the brace or is this something you pay for yourself? If not are there payment plans?. I tore my acl mcl and meniscus 11 months ago and have preseason in 2 months so I need a really good brace.

    • The Defiance is our custom made brace. It is made to the size and contour of your legs, it is a protective brace, it is not intended as a corrective device.

    • Would it be possible to order a Donjoy Defiance online without a CCM fitting ?
    • The custom Braces must be measured by a rep or someone with the knowledge of what numbers we need. I therapist can do a scan and send the AOP file to us.
  • From Francis at 11/11/12 6:29 AM
    • I tore my meniscus during pre season football and there was a server risk of my ACL being torn. Fortunately, it wasn't and I had a bucket handle torn meniscus. Would this brace help while playing football for protecting the knee?
    • Hello, Francis -

      The DonJoy Defiance III is a custom brace, therefore a rep or healthcare professional (doctor, physical therapist) would have to fit you for the item. As far as the functionof this brace, yes, it is recommended for prophylactic knee ligament support, the ACL in particular. If you prefer to use a standard (non-custom) knee brace that protects and supports the knee ligaments, we recommend either of the following: the Legend, 4titude, Armor, or Full Force.

      Thanks and have a great day!
  • From May at 11/16/12 10:41 AM
    • Is there a large print diagram of the directions on how to put on the knee brace, as the one in the box is too small for people like myself with vision difficulties. I prefer print over the video
    • Hello, May -

      Yes we do have something in print fo ryou. I will email it to you at the email you provided ( so you can either view it on your computer screen or print it out.

      Thank you and have a great day!
  • From Karen Shipman at 11/21/12 12:08 PM
    • A custom knee brace is a big financial investment, can you tell me how many years the brace is expected to last?
    • Hello, Karen -

      Our custom Defiance III braces are built to have an indefinite shelf life. We have a life-long guarantee on the hinge and frame and a 6 month guarantee on the soft goods (straps, pads). It's an extremely durable brace - many professional athletes use them in collision sports such as football.

      Thank you and have a great day!

Do you have a brace that he can wear under his shin guards and be able to move? He needs something that he can run in and keep his speed on bases and will give him great protection.
    • Hello, Mike -

      We recommend that your son speak to his athletic trainer or doctor, or whoever fitted him for the brace. Because we do not know the diagnosis of his knee, we do not know what type of support he needs as we have many braces to choose from that provide different types of support for diagnoses.

      If you would like to further discuss or have additional questions, we encourage you to contact our product specialists at 888-405-3251.

      Thank you and have a great day!

    • Will the straps still grab as tight after being in and out of the lake all summer long?
    • Hello, Jake -

      The straps should not be affected as the grip is made of hook velcro. However, if a brace is worn in water (pool, lake, ocean, etc), we recommend that after use, it be rinsed under tap water to remove any debris, salt, chlorine so as not to compromise the integrity of the straps and brace.

      Thank you and have a wonderful day!

    • How long does it take to get a brace re sized?
    • Hello,

      Normally the turn around time is 24-48 hours. Once you work with your sales rep or health care provider in getting the appropriate measurements, it will be submitted and made either the day of or the following day (depending on what time of day the request is made). It is then shipped out to you once it has been made.

      Thank you and have a wonderful day!

    • I have my ACL totally torn and my MCL partially torn and no plans to have them operated for the next year. I’ve been doing physiotherapy regularly and I need a brace that support my landings (I’m a skydiver and I need to run some steeps in my landings). Which brace is more recommended for my case? Thank you very much.
    • Hello, Fernando -

      The DonJoy Defiance Custom Brace with Fourcepoint hinge and ACL strapping sequence would be highly recommended for your activity and injury.

      Thank you and have a wonderful day!
  • From Gary at 5/13/13 7:25 PM
    • Please, I need some help. I torn my ACL months ago and I am wondering if this knee brace will help me to stalize my knee and don't keep making it worse. I will get a surgery, but not sure when yet. I am still running a bit but sometimes if I am on a slippery surface I have stability problems because of my torn ACL or if the terrain where I am running is not plane. Thanks
    • Hello, Gary -

      The Defiance III is an excellent choice to go with. I'm not sure what your question is, though.

      If you need further assistance or would like to ask any specific questions, please feel free to contact our product specialists at 888-405-3251.

      Thank you and have a wonderful day!

    • Hello, I had my ACL totally torn a few months ago and I won't be able to make a surgery till I finish my school. Is there any brace that can help me to play soccer without injuring my other ligaments?
    • Hello, Pedro -

      Unfortunately, even with wearing a brace, there is no 100% guarantee that other ligaments cannot be damages with activities such as soccer. The ACL does carry a majority of the load, so with an ACL tear, the other structures in the knee are compromised and more load will be put upon these structures as well.

      We do recommend the DonJoy Defiance for your needs, however we do stress that it does not mean that other structures will not be injured.

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

      Thank you and have a wonderful day!

    • Hi
      Is there any Donjoy rep in Brazil so I can buy and get measured in order to buy my Defiance.

      It works for soccer right?

      In case there is no rep in Brazil can I buy one online to be delivered to my friend who lives in CA without being measured?

    • Hello Sergio,

      The Defiance Knee Brace is a Custom Knee Brace, measurements must be taken of the person who will be wearing the brace. Your friend in CA should contact us so that we can setup a meeting with a CA Rep, so that he can be measured. Below find the contact in Brazil.

    • Hi.
      I practice martial arts(Aikido) as well as Parkour and Gymnastics. a year and half ago i had an ACL surgery and few weeks ago while i was running i found my ACL on same knee torn again !

      My plan is to redo my surgery few years from now. i have few questions:

      firstly, does the brace help for lifting weights, like hypertrophy training? squatting, lunges, etc. And if so, as i know legs may grow so fast, so the brace will be out of size so fast... any plan i can make?

      secondly, does it help to not get my meniscus get damaged?Also i heard with delaying surgery, there is a great chance to get arthritis. does the brace help it to be prevented?

      Thirdly, after doing the surgery, can i use DonJoy Armor or Defiance for post-rehab stage( after surgery stage)

      and finally, i am living in Malaysia, is there any distributes in Malaysia? how to apply for costume or off shelf braces?

      Thank you so much
    • Hello Akam,

      We do have a DJO Representative in Malaysia. Here you can find their information:

      The Armor Thigh Cuff and Calf Cuff are malleable, you can bend the bar out if needed, as your muscles hypertrophy. The custom can't be changed once it's made.

      Thanks for Contacting Donjoy.
  • From Chris at 7/16/13 10:29 AM
    • I have an old Townsend custom brace but it made my knee sore after use as I wasn't able to bend my knee all the way while playing sports due to the straps not being able to flex due to flexing of my calf . Is the Defiance III designed for full range of motion for the knee?
    • Hello Chris,

      Yes, all our off the shelf bracing and Defiance Custom Brace allows for Full Range of Motion. If you would like to limit the range you have the brace is adjustable by inserting flexion stops into the hinge. A Donjoy Representative and help you with this.

      Thanks for Contacting Donjoy.
