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
Bill
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
jamar
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
Sid
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
Frank
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
TippyToes
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
Em
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
Sweetwater
If it wasn't for my Defiance knee brace I wouldn't be able to play a lot of the sports I love. At the age of 47 I am back playing softball, volleyball and other activities that used to worry me with my knee stability. I don't know why anyone wouldn't take advantage of the stabilization advantage of these DonJoy knee braces. I'd love to know if my old WC claim would support me getting an upgrade for the new Defiance III, but even so I might look into it anyway. - Sweetwater
Blake
I bought this knee brace a little over 2 years ago and i had severe knee pain as a high school football player. I bought this brace and wore it for about 8 months and NOW i don't even have to wear it anymore! It's as almost as if the brace fixed my knee! INCREDIBLE! - Blake
Smooch
It fit like a glove and never bothered me to wear it at all. Felt comfortable right away. Had meniscus surgery and didn't think I'd be able to run again, but this brace made it possible. - Smooch

Questions on DonJoy Defiance III Custom Knee Brace

Sort by Ascending
  • From David 808 at 6/17/2015 7:28 PM
    • Does the DonJoy Defiance provide a distraction (separation ) of the knee joint, for use on osteoarthritis knee pain?
    • The DonJoy Defiance has the option to get the OA hinge. The bilateral hinge bars offers support for ligament instabilities and work in along with the telescoping condyle pad which gives you the ability to control the amount of offload in the brace, to provide relief for your osteoarthritis. When you are being measured for the brace by the DJO Sales Rep they will go over your injury and help to determine if this option is best suited for your needs,
  • From Mike at 4/26/2015 1:50 PM
    • I am a Police Officer and was injured in the line of duty. I completely tore my ACL, both Meniscus were torn, and I have a lot of kneecap instability along with Stage 1 Arthritis. I had surgery Jan 2015 to repair the ACL and meniscus, and am still going through physical therapy. However, the brace that my Doctor ordered hurts my kneecap, and I am going to request another brace. I am leaning towards the Defiance because I not only want the best, but I also don't want to re-injure everything when I am able to return to duty. Is this the best brace for my injuries?
    • Yes the Defiance is the best brace for your situation. You can get a tru-Pull attachment installed on the brace to help with patellar instability if you want as well. The Defiance is our strongest brace and would hold during the work you do.
  • From Bryan at 3/18/2015 12:06 PM
    • I recently tore my ACL and was looking into a knee brace to support it before I get surgery. Would the defiance III be a brace I would wear pre/post surgery? And would it allow me to play soccer while wearing it?
    • The Defiance can be worn before surgery and after. You will just need to make sure that you are measured when you knee is not swollen or atrophied, be cause there is only one free re-make within four months. Usually if the brace is fit before surgery and you have no swelling then by the time you are ready to wear the brace after surgery is will still fit. There is no guarantee that you can play soccer even with the brace before surgery. The brace will protect the knee but cannot make up for the strength in your knee and leg muscles that is lost after injury.
  • From Paige at 2/21/2015 10:07 AM
    • I had surgery on my right knee and would like to return to playing soccer, softball, and basketball. However in soccer it is my dominant kicking leg and I am a strong kicker. Which kind/type of brace would be the best for these sports?
    • The Defiance is our best knee brace for someone who needs to return to sports activity. The brace is made specifically for your knee only and has our fourcepoint technology to help protect against re-injury.
  • From Alan at 12/9/2014 7:24 AM
    • I have a knee brace that I purchased in 1996. How do I obtain replacement pads for it?
    • If it is a Custom brace there is a small sticker on the inside of the frame right below the outside condyle pad. The sticker has the brace serial number on it. You will need this number and can order replacement softgoods by calling 800-336-6569, option 1, option 1, and option 1 for Defiance orders. If you do not have a Defiance you can find your brace on our website and get replacement parts there. http://www.betterbraces.com/donjoy-replacement-parts/knee-braces
  • From Javier at 12/1/2014 10:41 PM
    • My son's MRI has detected a complete tear of his ACL and a TINY tear in his meniscus. There is no other damage to his knee. We are weighing options but are looking at the possibility of wresting and/or baseball for this his senior year. Any recommendations on knee braces. If any metal is showing it would have to be padded over.
    • Javier
      If your son is not having surgery then he wold have to wear one of our rigid knee braces to have any chance to play sports. DonJoy Full Force Ligament Knee Brace http://www.betterbraces.com/donjoy-fullfource-ligament-knee-brace This brace is patient ready and can be ordered off this website.
  • From Aspen at 10/24/2014 7:11 PM
    • Hi there,

      I tore my ACL and MCL over the summer and was wondering if the Defiance III brace would work for ice hockey and pole vaulting? I'm also only 5'2 so I was wondering whether a Short thigh or a Standard thigh length would be better?
    • The Defiance would work with both of those sports and yes you would want the short thigh and shot calf on the frame.
  • From Justin at 6/9/2014 6:50 PM
  • From Alexandra Fox at 5/27/2014 12:26 PM
    • What is the best brace for a women's soccer player when is returning from Acl surgery?
    • The best brace for a female soccer player returning to play from an ACL injury would be one of 2 braces. The Defiance, or the FullFource/FemaleFource. Both come with a short calf option (Great for shin guard accommodation) and the FourcePoint hinge, which gives extra protection to the ACL.

      The protection level is the same. The difference is the Defiance line is custom fit, and has a life time warranty on the frame and hinges. Also, The Defiance line is a carbon fiber material. The FullFource/FemaleFource is aircraft grade aluminum and has a 1 year warranty on the frame and hinges.
  • From Jimmy at 5/26/2014 12:09 PM
    • My patella ligament dislocates. This brace looks great, but is there something that would be able to secure my patella?
    • The Defiance III brace can have a tru-pull attachment add on to allow for patellar stability.
  • From Jeremie at 4/18/2014 2:10 PM
    • Hello
      I have a partially torn acl and this will be the third time i will be getting surgery. I'm currently in the market for a light weight small acl brace that will allow me to play soccer on a semi pro level. Is there anything that you would recommend? Also can you tell me how these braces compare to the townsend premiere acl braces?
    • The Full Fource or the Defiance III would be appropriate choices for you. Both come in a short option which is preferred by soccer players as it allows for shin guards to be worn without interference. The defiance III is the custom brace, carbon fiber 22 oz and lifetime warranty on the frame and hinges. The full fource is an Air-Craft Grade Aluminum, it is 20 oz and has a 1 year warranty on the frame and hinges.

  • From Philip at 3/25/2014 2:04 PM
    • Would this be a good choice for tennis or would the Full Force be a better option for non contact sports?
    • Both braces would work for playing tennis. The differences are that the Custom is made of a carbon composite has a lifetime warranty on the hinges and frame and is made specifically for your leg for the best fit. The full force is made of aluminum has a one year warranty on the frame and hinges and is patient ready so you only need three measurements and look for you size in a sizing chart.
  • From Patrick at 3/16/2014 5:17 PM
    • My primary issue is missing meniscus cartilage on the right side of my right knee (due to damage after an ACL tear). Now when I run too much, I start to get pains in that area. Would this knee brace reduce the impact on my knee overall, or is it just designed as relief for the ACL?

      Thanks,
      Patrick
    • The Defiance can be made with an OA adjustable hinge. This hinge would be on the lateral side in your case and can unload that side where you had your meniscus tear. So the brace will protect your ACL and unload the side of your knee where you have your pain.
  • From Angelo at 2/17/2014 7:29 AM
    • I have had an ACL reconstruction surgery after It was fully torn, and I seem to have re-injured the same knee a year later with a minor tear.

      I practice Parkour and variations of Gymnastics, that typically involve myself landing prominently and only on my injured knee (Hard and forceful landings).

      I do not want to sacrifice speed/power/flexibility or anything that hinders my movement as much as possible, but I still want full protection for my torn ACL.

      So, my question is, which Knee brace should I order? A Donjoy Defiance or a Donjoy Fullforce?
    • Thank you for your question. The 2 major differences between the FullFource and the Defiance line are going to be 1. The materials and 2. The warranties. The FullFource is made of aircraft grade aluminum and the Defiance is a carbon fiber. The warranty on the FullFource frame and hinges is 1 year and the Defiance has a lifetime warrant on the frame and hinges. Both braces will be light weight weighing about 22 ounces, allow full range of motion and protection to the ACL. The Defiance allows for more variation in color and styles as well as a custom fit.
  • From Steve at 1/29/2014 6:31 PM
    • Would you recommend this brace to someone who is an avid basketball player who has never had any ligament surgery (or injury) before, but who is looking to protect his knee ligaments in general?
    • Yes, this brace can and is used to prevent injury to the knee. Both the Four points of leverage strapping system and the FourcePoint hinge technology available with the brace have been clinically proven to prevent ACL tears up to 50%
  • From Eric at 12/28/2013 9:09 PM
    • I have a partially torn ACLU, which my doctor cleaned up, but said he didn't need to replace as he could not make it fail during surgery. However, I did have a lateral meniscus transplant, ACI and distal femur osteotomy in the same knee last month. My doctor said I may want to go with the Defiance OA in order to keep the lateral side "jacked open" during sports. I don't see the defiance OA on this site though and wondering how to order. Thanks. Also, do you agree this is the best brace?
    • This will be an excellent brace for you ACL and meniscus problems. You would order the DonJoy Defiance brace. When the rep contacts you, you would let them know it is going to be an OA brace.
  • From Mandie at 12/13/2013 1:16 PM
    • Hi, I partially tore my ACL in my left knee in September. In October I had acl reconstruction. I'm hoping to be back to playing soccer in the late spring but I want to have a knee brace for support and more peace of mind. what do you suggest is the best? I really don’t want to tear it again.
    • The Defiance Brace is the best knee brace for you to wear after a ACL recontruction to protect the knee. It is custom made for your leg only and it has the combined technology of our 4 Points of Leverage Strapping and the fourcepoint hinge which both have been clinically proven to reduce ACL tears up to 50%. If you are interested in getting this brace you can get in contact with your local DJO rep, either through your doctors office of you can contact product support at (888) 405-3251 and we would be happy to get that information for you.
  • From Adam c gargir at 12/11/2013 10:59 AM
    • How does the defiance for OA, compare to the other custom OA braces. I am a police officer, and need a reliable brace, that can with stand the riggers of my job.
    • Adam
      The Defiance OA brace is our best OA brace. It is measured specifically for your leg only to maximize the best fit. It also can accommodate up to 10 degrees of correction where our off the shelf braces will only accommodate 3-7 degrees. The frame is made of a strong carbon composite that is lightweight and durable. This is the same frame that we use for pro football players braces.
  • From Dat at 12/10/2013 12:25 AM
    • I am a volleyball player and have a torn ACL and cartilage damage. I am a senior so I decided to play my last season in high school with a bad knee. My doctor said that if I want to play; my cartilage might get too much damaged that they won't be able to fix it. So I wonder if this knee brace will help me preventing that from happening and also help my knee get stronger. Do I have to wear it while walking too or just when I run, practice, and compete? Thank you
    • The defiance brace is designed primarily for ligament instabilities. This would be a great brace for your ACL injury. If the cartilage damage is on one side more than the other, you may want to look at a brace from the DonJoy OA line. The OA braces are designed for Osteoarthritis and meniscus injuries and can be combines with ligament strapping for the ACL.
  • From Chris at 11/14/2013 5:02 PM
    • My son just tore his ACL and MCL playing High School Football. He is an Offensive Lineman and weighs 240 lbs. Would the Defiance Custom Brace provide the best protection available for an Offensive Lineman?
    • The Defiance III would be an excellent choice for your son. This brace comes standard with the swooping thigh and swiveling tabs, which are great for athletes. It would be recommended that you also go with the metal power caps and reinforced fiber frame since your son plays a contact sport. If you would like to have your son measured, you can give us a call to get the name and number for your local rep.
  • From The Long at 10/14/2013 12:06 AM
    • I'm participating in muay thai boxing. I had acl surgery. Is this a good brace for me when I start full training again? I also live in Vietnam and my uncle lives in the US. How can I get this brace?
    • The Defiance III custom knee brace is our best brace for return to high activity after ACL reconstruction. If you wanted to get this brace you would need to be measured by either a medical professional or a DJO representative. We do have other options that would only require a few measurement that you could do on your own and your Uncle could order the brace for you in the US. Take a look at the Armor http://www.betterbraces.com/donjoy-armor-knee-brace-with-fourcepoint-hinge or the Full Force http://www.betterbraces.com/donjoy-fullforce-ligament-knee-brace. Both of these braces are used for contact sports and have the same Four-Points of Leverage and FourcePoint hinge technology that reduce re-injury of the ACL by 50%, that the Defiance III does. You would only need to measure 6 inches above your kneecap, 6 inches below the mid knee and at the knee joint and find the size that corresponds to those measurements.
  • From Ed at 9/30/2013 9:28 AM
    • I'm a offensive lineman a sophomore who was on varsity i dislocated my patella 5 times and I'm getting MPFL reconstructive surgery is this brace a good option for me?
    • The Defiance Knee Brace is our custom brace used primarily for prevention of ligament injuries and post ligament injuries. This is a good brace for you in that preventative aspect. I recommend you add the tru-pull attachment to this brace to support the patella.
  • From Race at 9/25/2013 12:13 AM
    • Hey, I am looking for a brace for snowboarding. I tore my ACL and got surgery on it and would like a brace to feel more comfortable. I am looking at 3 different braces from you guys and wondering which would be the best. The Defiance III, the Armor ski version or full force? I am sure the Defiance is the better one but do i need a custom brace over an off the shelf and is it worth the 300 bucks more or so? If i can't afford the custom brace which of the two would be better for snowboarding? The Armor or Full Force? Thanks
    • Both the Armor and the Fullforce (as well as our defiance III) come with ForcePoint hinge which I would recommend you get. It's an added ACL protection option. The armor is the strongest brace we make at .125" thick. I would first consider that brace over the FullForce for you. We recommend this brace for contact sports (and snowboarding can be as much a contact sport as some other traditional sports). Both the FullForce and the Armor come in a short option; depending on how tall you are and how high your boots come up you may think about going short. a standard brace will be 18" in length and the short will be 17" bringing it up on the calf an inch higher.

    • My name is Yacine and I'm a football player in Sweden. I play as an offensive lineman and I'm currently looking for two braces, one for each leg.

      I've torn my PCL ligament in my right knee and I'm suffering from overloading in my left knee. Therefore, I'm currently looking for two knee braces. One brace that will help my right knee with the PCL rupture and one that will help my left knee from getting overloaded and risking to tear something off.
    • The Defiance III would fit you the best it is custom made to your leg's specifications, these are the same braces NFL Lineman wear to protect their knees.

    • Hi There,

      6 weeks ago I had an operation to reconstruct and reattach pretty much my entire PosteroLateral Corner of my knee as well as my ACL. The Surgery was successful. Doctor has however said that it will be difficult for me to Play Soccer/Football again due to the Pivoting? (I know this would only be in over a years time). He said mainly due to the fact that the PosteroLateral Corner was very badly damaged. Does the Donjoy Defiance III Custom Knee Brace protect the PosteroLateral Corner of the knee and will it allow me to play my sports again? Or is there a better knee brace for this injury?
    • The Defiance Knee Brace is a Custom ACL Brace. We also have Off the Shelf ACL Braces, the Armor, and Full-Fource, all feature the FourcePoint hinge which prevent the knee to go into hyperextension.
  • From Amber at 8/6/2013 9:28 AM
    • I'm looking for a good ACL brace (for my partially torn reconstructed ACL) that would last playing beach volleyball without the sand ruining the hinges. This one looks like it has a slightly different hinge than my current Dongjoy Knee Brace (Donjoy Armour) - will this brace, or another Donjoy brace work well in the sand without getting ruined? Another one I checked out was the Defiance III Female Fource.
    • Anyone of our braces can be used for beach volleyball. I recommend rinsing the brace out with water after use, to make sure all sand is removed from the hinge. I recommend the Armor, due to the diving/hitting the ground, this brace frame is more rigid and will hold up.
  • From Francesca at 8/5/2013 8:57 AM
    • I am an 'at risk female' with an ACL reconstruction on both my left and right knees. I play Ultimate Frisbee and need to be able to cut, sprint, jump, change direction, dive ...etc. Can you wear a brace on both knees and still move freely?
    • Yes, I recommend wearing a ACL Knee Brace to protect your recent ACL reconstruction. You have the option of our Custom Defiance or our off the shelf knee brace Armor.
  • From Chris at 7/16/2013 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?
    • 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.

    • 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.
    • The DonJoy Defiance Custom Brace with Fourcepoint hinge and ACL strapping sequence would be highly recommended for your activity and injury.
  • From RFR at 3/19/2013 3:22 PM
    • I am looking for the best knee brace you have that can be used for skiing and other sports. I have had two ACL reconstructive surgeries on my right knee in '91 and '06. Can you provide both a custom model and off the shelf model?

      Thanks
    • Yes, The Defiance III with FourcePoint hinge, for off the shelf, the Armor with FourcePoint hinge and a short calf.
  • From Sally at 2/18/2013 7:40 AM
    • I would appreciate a printed copy of how to put the knee brace on as the
      video instructions are hard for me to follow. Thank you
    • Hello, Sally -

      You were emailed a printed copy of instructions on how to put the brace on.

      Thank you and have a wonderful day!
  • From Undine at 2/14/2013 10:31 PM
    • How long does it take to get a brace resized?
    • 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.
  • From Jake Smith at 1/25/2013 9:15 PM
    • Will the straps still grab as tight after being in and out of the lake all summer long?
    • 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.
  • From Karen Shipman at 11/21/2012 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?
    • Our custom 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.
  • From Francis at 11/11/2012 6:29 AM
    • I tore my meniscus during pre season football and there was a servere 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?
    • 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.

  • From Bob at 3/25/2012 2:16 PM
    • How do you wear soccer shin guards with one of these knee braces?
    • The brace comes in two different calf lengths. If you are concerned with shin guard clearance, I suggest ordering the "short calf" version.

  • From jeff at 3/19/2012 2:18 PM
    • Is the defiance III suitable for playing basketball. I had an acl injury and a meniscus tear.
    • Yes, the Defiance III is a great brace for basketball among many other sports and activities.
  • From Chris at 11/2/2011 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?
    • 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 collegiate and professional football players as well as other high contact or extreme sports athletes. The Defiance also has our 4-points-of-leverage system, which helps with fit and suspension. 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 compromise 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.

  • From Laurie at 8/27/2011 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 andrew at 8/15/2011 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 Kyle at 6/1/2011 10:37 PM
    • I have just had my 4th acl surgery. I am 16 years old and love sports and never see myself quitting. 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 therapy and by my doctor who is ranked in the top 10 surgeons 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 Tammy at 4/18/2011 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. You will not be able to wear it under tight jeans, so wear it over the jeans in that case.
  • From John at 3/7/2011 1:36 PM
    • Can I use the brace in the water? (Water Skiing, Surfing, etc.)
    • Yes, you may use the Donjoy Defiance III in water. Uust 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 Frank at 12/13/2010 8:28 PM
    • 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 it's too heavy. Would DonJoy Defiance III be better instead of the Townsend Full shell knee brace?
    • The DonJoy Defiance III will fit better than any off the shelf brace due to the fact that the brace will be custom built for your leg contours.
  • From Zach at 9/18/2010 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,

      -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.
  • From scott at 7/31/2010 10:44 PM
    • Is a custom fit brace good for a 16 year old boy that is still growing?
    • The DonJoy Defiance III Custom Knee Brace is ideal for a growing patient. First of all, you'll get a size change remake within 4 months, free of charge. Secondly when the patient does grow beyond the brace measurements, a remake will cost significantly less than ordering another off the shelf brace.
  • From Jason at 5/19/2010 2:47 PM
    • Do you need a prescription?
    • No, you do not need a prescription to order the Defiance. You can place the order online and once it has been ordered, a DonJoy Sales Representative in your area will contact you to schedule an appointment to be measured for the brace.
