Speed and Performance Matter

When speed and performance during non-contact sports matters, you don't want to get slowed down with heavy, bulky braces. The DonJoy A22 custom knee brace provides the perfect balance of weight, strength and support to keep you healthy and protected while performing your favorite daily activities.

The A22, the world's first titanium brace, is custom made for your knee ensuring maximum protection for the ligaments in your knee. The low-profile, aerodynamic integration of the straps and liners make this custom knee brace light and less bulky so it won't get in your way during activity while providing the best protection for ACL injuries.

With the risk of ACL injuries and even a second tear, it's extremely important to protect your knee ligaments. A person who has torn their ACL has a 15 time greater risk of another ACL injury. The risk of an ACL injury to the opposing knee is 2 times that of the reconstructed knee. These stats confirm the importance of supporting your knees during any activity. The A22 custom knee brace is the bracing solution to keep you active and performing.

If you are involved in contact sports like football, motocross, or skiing we recommend the DonJoy Defiance III custom knee brace.

Why do I need a custom knee brace?
Wearing a custom knee brace means maximum support where you need it most. You do not need for a prescription to purchase this brace. When you order a DonJoy A22 custom knee brace, one of the DonJoy bracing experts will contact you after your purchase to schedule a fitting appointment. Then DonJoy will customize a brace to fit your exact measurements. The customized fit ensures all of the components of the brace align perfectly with your body for maximum protection and comfort during movement.
Get back to your sport with confidence because the A22 custom knee brace provides top-notch technology to protect against ACL injuries.

The A22 custom knee braces are used to treat or prevent the following injuries:

A22 Features...and the benefits you'll experience:
Whether you're participating in non-contact sports or your daily activities, the A22 custom knee brace protects your knee without the feeling of a heavy, bulky brace.

FourcePoint Hinge Technology (Stop kit not included):
Makes you less likely to suffer from an ACL injury because it reduces the amount of time your knee is in an "at-risk position", enhances the Four-Points of Leverage by increasing the posterior load applied by the brace on the tibia, and improves your natural gait by applying progressive resistance before reaching a firm end point during movement
Improved joint mechanics and symmetry between both knees

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

Low profile, aerodynamic integration of straps and liners equals less bulky than most knee braces-you won't notice you have one on

The revolutionary design of this custom brace ensures you can participate in your activities in complete comfort

Anti-microbial coating helps eliminate odors and skin irritation

Cushioned pads reduce shock on your knee and provide additional stability

Anti-migration keeps your knee brace in place no matter how active you are

Upon placing your order, we will contact you to schedule an appointment with a local representative to take your custom measurements.

  • Quana at 8/8/2016 3:40 PM
    • Hello, I recently underwent a reconstruction of my ACL and meniscus. I am 20 y/o and currently playing college basketball. The new ACL was constructed using a piece of my hamstring from the same leg and 2 cm of cadaver . I am extremely active and will be returning to my sport in November. I need a strong lightweight brace that will be able to take somewhat of contact. What brace will be best for me and which one will I have better results from? I was looking between the A22 or the Defiance III .

      Please and thank you.
    • The Defiance III would be the better option, as the A22 is not suggested for contact sports.
  • Daniel at 8/3/2016 2:17 PM
    • My surgeon is recommending I get fitted for a custom brace post ACL surgery, mainly for skiing, but also for tennis, basketball, soccer and surfing. I'm in between the A22 and Defiance III. I like the idea of the A22 being lightweight and comfortable (I'd be more inclined to wear it), but noticed it doesn't come in the short calf version, though it has a hybrid height. Will it fit above my ski boot (I'm 5'11")? For my needs, would you recommend the A22 for me? Last, is the A22 waterproof?
    • The A22 comes with a hybrid calf length which is 7 inches from the center of the condyles to the bottom of the brace. The total length of the brace is 15.5" Yes, you may wear it in water. The A-22 would be a good choice for you.
  • Stacey C at 7/27/2016 3:33 PM
    • Where can I get replacement pads and straps for the braces?
    • You can order the replacement strap kits through DJO Global at 800-336-6569 for the A22
  • Christianq at 7/15/2016 3:29 PM
  • Mollee at 5/11/2016 7:01 PM
    • I am an 18 y/o female that will playing college softball in September. I just had a complete tear of my ACL and a lateral meniscus tear that was repaired via scope. The new ACL was constructed using a piece of my hamstring from the same leg. What brace do you recommend knowing I will be playing softball and will for the next 4 years at a very competitive level.
    • The best brace to wear while playing softball would be either the Don Joy Armor or the Don Joy Defiance. The Defiance is our custom ACL knee Brace with the Foucepoint hinge will provide the best support and protection to the ACL. The carbon fiber frame is tough enough to withstand contact. The brace is custom fit for your leg only and has a lifetime warraty on the frame and hinges
  • Marlon Naidoo at 5/7/2016 11:15 AM
    • Does insurance cover cost
    • Insurance usually does cover these types of items but we do not accept insurance on the website. You can take a prescription to your local AirCast sales rep to get insurance to cover all or a portion of it. Follow this link to find your local rep
  • Denise at 4/17/2016 12:32 AM
    • Chronic Patellofemoral pain, both knees. Lateral release surgery, both knees. Major instability, both knees "give way".

      Adventure motorcycle rider so this is a tad problematic. Need maximum amount of dynamic protection and support against joint instability and lateral tracking.

      Saw Tru-Pull Advanced Attachment for patellar support on Donjoy's website, but not here. So my questions are:
      1. Can I order the A22 with Tru-Pull Attachment?
      2. If so, what other options are available?
      3. Even if this option is available, in your opinion, would it be effective kneecap/patella support?
      4. What are some other comparable options?
    • The Tru-Pull Avanced Attachment cannot be added to the A22 custom knee brace. The Defiance would be a suitabkle substitue.
  • Gloria at 4/3/2016 12:08 PM
    • My son, 15, tore his ACL while playing basketball. His surgeon gave us a prescription for a custom brace and would like for him to use it for about a year, after he clears him which will be in about 3-4 months. Two questions, which brace do you recommend for this sport. Second, since the brace is custom, and the doctor wants him to use it in his rehabilitation, is he going to have a problem with outgrowing it?
    • The A22 is a custom brace and would work well for a basketball player because it is low profile and light weight. When you get a custom brace from us you have 4 months after the first brace is made to get a one time free remake for girth changes. After 4 months there is a charge for the re-make but less than purchasing a new brace
  • Donna at 3/14/2016 4:36 PM
    • I tore my MCL surfing last fall and am looking to get back out this month. Am a female, size 2, and looking for something supportive and not too heavy. Is this sufficient for surfing?
    • The A22 is a light weight low profile option that affers maximum knee protection and would be a good choice for someone surfing
  • Camilo at 3/14/2016 1:59 PM
    • Is this brace suited for surfing? I have reoccurring meniscus and mcl issues after surgery and no typical brace has provided the correct support to the knee. With my high level of surfing my knee is put under lots of stress of the knee bending inward and twisting which is how I initially injured my knee. What would be the best brace for a competitive level of surfing?
    • The A22 or the Custom Defiance would be the best braces. The A22 is a lighter lower profile brace and might be the better choice for you
  • Dilian at 3/13/2016 2:35 PM
    • Hello, I recently underwent reconstruction to my ACL, PCL, LCL and repair to my MCL. I'm 24 years old and an ex D1 soccer player who would like to get back on the pitch. Which brace would you recommend for me? Thank you in advance.
    • The Don Joy Armor with standard hinge would be the best choice for a "patient ready " brace. the frame is a strong aluminum and the brace will support all of the ligaments and help to protect from further injury
  • Chimdi at 3/12/2016 11:49 PM
    • How much does it weigh? How come it shouldn't be used for football?
    • The brace weighs 19.2oz and the frame is made of titanium which is stronger than aluminum but not as strong as our carbon fiber brace the Defiance. We cannot guarantee that the frame will withstand contact that will happen during football.
  • Mari Russell at 3/7/2016 6:55 AM
    • Does it come in different colors?
    • No it does not
  • Ben at 3/2/2016 9:35 PM
    • I have used my defiance don joy brace for about 5 years while playing softball and I am looking into a newer up to date brace like the a22. I just had my 2nd acl surgery and my meniscus repaired and I want to still play at a high level for the next 5 to 10 years. Is this brace a better version of the defiance or just a more compact lighter one?
    • The Defiance is still the best ACL brace that we make and more suited to activites that have contact involved. The A22 is a lighter more lower profile version of the Defiance. The brace uses the same 4 points of leverage strapping system and fourcepoint hinge but has a lighter titanium frame and is not reccommended for contact sports or activities
  • Janet Bennett at 3/2/2016 8:38 AM
    • Deciding between A22 and Defiance. I work in a hot climate and am concerned about slippage. I like the profile of the A22 more but am concerned about movement. Is one better with this than the other?
    • The liner for the Defiance is either suede or chamois material. Chamois would work better with sweating. The A22 has a anti-microbial liner with silicone on it to help prevent sliding. A good fit should prevent slipping
  • Peter at 2/29/2016 7:51 PM
    • Hello, I have recently had a surgical procedure done due to ACL tear. My doctor said that I won't be needing a brace. Do you recommend me getting a brace since I play college and which knee brace do you recommend?? And will it bother me or not while playing?
    • You should speak to your physician further about wearing a brace while playing college athletics. I can tell you that one of our braces with the fourcepoint hinge such as the A22, and Full Force Ligament knee brace have been clinically proven to help prevent re-tear of the ACL up to 50 %. The hinge has a dampening effect that will slow down the last 20-25 degrees of knee extension which keeps the knee out of the "at risk" position.

  • Dawn at 1/29/2016 4:16 PM
    • I had ACL reconstruction in both knees about 22 years ago and now at 38 - I found out my meniscus is torn and I'm ACL is hanging on by a thread. Due to arthritis in my knees ACL surgery is not an option again. What brace would you recommend for exercising or playing with my kids.

    • A functional knee brace will provide your knee with the stability it is missing from the ACL. If you are looking at a "off the shelf" brace then take a look at the FullForce Ligament knee brace. If you would like a more custom fit the A22 is a great option. Both braces off ther Fourcpoint hinge witch will offer the best ACL protection.

  • Alam at 1/7/2016 9:58 AM
    • I am looking for brace primarily for hiking/backpacking where my main worry is with descending down. I have hurt my knee that way taking big steps descending down and now I am extremely careful and have considerably slowed down my pace to protect my knee. I am otherwise fast hiker though, by some standards rather an extreme hiker because I have hiked 30 miles in a day gaining 9000 ft in elevation and losing the same. I am deciding between armor, defiance III and AC22. I definitely like the low profile, titanium and less weight which is ideal for what I want to use it for (keep weight minimum, maintain good pace). But will it be able to handle hiking downhill on rocky terrain with decent pace? Is the other braces has any advantage over it in terms of performance? I also intend to use it for tennis, running.
    • The A22 is an excelent choice for you. The brace is going to offer you maximum support and prevention of ACL injuries and can be worn during any activity.
  • Gary at 12/8/2015 8:26 PM
    • Hi, does A22 come with short calf option?
    • The A22 comes with a hybrid calf length which is 7 inches from the center of the condyles to the bottom of the brace. The total length of the brace is 15.5"
  • Alexis at 12/4/2015 9:18 PM
    • I was just curious if I could find out where these sizing experts are located? I live in a more rural area in Montana and would like to know this information before I buy this brace.
    • Hello,
      Thank you for quesiton. Any of our Brace Advisors can assist you with sizing questions. Please contact a Brace Advisor for assistance at 800-553-6019.

      Have a Great Day.
  • Sarah at 11/30/2015 10:10 PM
    • Hi, I have a ruptured left ACL and am having surgery in the next couple of weeks. I'm an ice hockey player as well as lacrosse. I am trying to decide which brace, the A22 or defiance III would be better.
    • Sarah
      Both braces will function the same way and have the same technology. The A22 is a lighter brace and it has a lower profile frame so it doesn't seem as bulky. This might be your best choice
  • Gary at 11/27/2015 1:26 PM
    • Hi, I had acl recon surgery a year ago. now I am getting back to sport. I mainly play basketball and mountain biking. which is a better fit for my activities, A22 or Defiance?
    • Gary
      Either brace will work for you but the A22 is lighter than the Defiance so if that matters to you then choose the A22
  • Ross at 11/9/2015 9:41 AM
    • I play linebacker in football. Would this brace be good for this? I also run track.
    • Ross
      Yes you can wear this brace for those two things
  • Evan at 11/6/2015 10:19 PM
    • I had ACL recon surgery about 2 months ago, and am looking for a good sport brace. I play football, run track and dance. My Dr. recommended FullForce brace, but with so many I don't know which one to get. What brace would be best?
    • Evan
      The Full force is a great brace and can be worn with all of the activities that you mentioned except if you play lineman on the football team. I you play this position it would be better to go with the Don Joy Armor knee brace as it is a thicker frame than the Full Force. http://www.betterbraces.com/donjoy-armor-knee-brace-with-fourcepoint-hinge

    • What is the HCPCS code for the A22 Custom Knee Brace
    • L1846

  • Luis Lee at 10/22/2015 6:51 PM
    • Hello, I had acl reconstruction and after the rehab my knee is very strong, i am using my donjoy armor just to be able to play with confidence, so the question is why should i change my armor for an a22? What's the weight of the a22?
      Thank you
    • Luis
      The functionality of the Armor and the A22 is the same. They both have the " Four point of Leverage" strapping system and the fourcepoint hinge to protect the ACL. The difference is the material of the frame, weight and profile. The A22 is a Titanium frame weights 19 oz and is a lower profile frame. The A22 is not recommended for contact sports. The Armor is a aluminum frame and weighs 24 oz
  • Andrea at 10/22/2015 6:51 AM
    • Does the A22 also come in an osteoarthritis brace ? As an offloader like the Custom DonJoy OA Defiance ?
    • Andrea
      At this time we do not offer the A22 in a off loader. We will in the future
  • Andy at 10/10/2015 4:53 AM
    • I just recieved a new Fource Point A22 Custom Knee Brace purchased fro by the Veterans Admin Hospital, there was absolutely no problem getting used to the brace. My question is; how do I purchase more A22 undersleeves? It came with 1 but I would like to purchase more of the undersleeves.
    • Andy
      You can purchase replacement under sleeves by calling DJO Global direct at 800-336-6569
  • Robert at 10/6/2015 12:23 AM
    • I have a fully torn ACL in my right knee and a partially torn ACL that I have rehabbed in my left from a prior injury. As a police officer who still works patrol, would the A22 be a good choice for both knees or the Defiance III? I like the idea of low profile and lighter weight for 10 hours shifts but def need the protection. Thanks!
    • Robert
      The A22 would be a good choice for both legs. The brace is light weight and low profile but still has all of the technology to protect the ACL.
  • Slava at 9/11/2015 1:36 PM
    • Diagnosed with Grade 2 PCL injury. Recommended this brace but warned that is not on the market yet. I see it now on your website and wonder if i could order it here. If not available, I would appreciate an advice on alternative options (less cumbersome, possibly wrap-around style). I cycle and run. Thank you.
    • Slava
      The A22 is NOT reccommended for a PCL injruy. The brace has our patented fourcepoint hinge which will put stress on a torn PCL. YOu want to get a brace with our standard polycentric hinge. If you are interested in a custom brace then you will need to look at the Custom Defiance knee brace. http://www.betterbraces.com/donjoy-defiance-iii-custom-knee-brace The brace can be purchased here and then ou make an appointment to get your knee measured so the order can be placed
  • Brent at 8/7/2015 8:47 PM
    • I have some serious knee issues. I have had 3 prior surgeries on my left knee. My last 2 were lateral and medial meniscus tears. I have nothing left and I am stage 4 OA. I will eventually need a knee replacement. Could this particular brace still work for the injuries that i have? I like the fact that it is custom made for the individual person. I want a good fit if I am still going to be active (functional fitness and/or possible crossfit). I will eventually need a knee replacement. I am hoping this custom made brace would be useful for me. Or is there other custom made braces for active sports that will eventually need a knee replacement? thanks.
    • Brent
      The A22 is not for OA but we do have a custom brace that you can get for OA, the Custom Defiance can be customized for an OA patient. http://www.betterbraces.com/donjoy-defiance-iii-custom-knee-brace
