Product Features…and the benefits you’ll experience!

Custom Fabricated Based on Your Measurements
The brace is manufactured to your exact measurements, which means the components of the brace align perfectly with your body ensuring support, protection and comfort during movement.
Available in 3 Lengths
The DonJoy Defiance is available in 3 lengths: standard, short, and a short calf version for ski boot clearance.
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 exactly how the Four-Points of Leverage works.
LowPro 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.
Carbon Fiber Frame
This brace is both unbelievably strong and lightweight. You get the protection you need without feeling like you’re being weighed down by your brace.
Anti-migration Supra Condyle Pad
Your knee brace will stay in place no matter how active you are.
Swiveling Strap Tabs
These tabs enable the brace to move with you.
Product Guarantee
This knee brace comes with a lifetime warranty on the frame and hinges, and a 6 month warranty on the soft goods.

Product Questions

Is a custom fit brace good for a 16 year old boy that is still growing?
Question by: scott on Jul 31, 2010, 10:44 PM
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.
Answer by: Admin on Jul 31, 2010, 10:44 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
Question by: Zach on Sep 18, 2010, 1:44 PM
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.

Does the DonJoy Defiance provide a distraction (separation ) of the knee joint, for use on osteoarthritis knee pain?
Question by: David 808 on Jun 17, 2015, 7:28 PM
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,
Answer by: Admin on Jun 17, 2015, 7:28 PM
How adjustable is this brace? Will it allow for growth in the leg both vertically and horizontally? If it will how much will it allow before you need a new brace?
Thanks
Question by: Alex G on Jan 4, 2016, 5:57 PM
The Defiance is custom made for your knee size as it is and you have 4 months to get one free re-make for girth changes. After 4 months there is a charge for a re-make.
Answer by: Admin on Jan 4, 2016, 5:57 PM
One Size.
