About the DonJoy A22 Custom Knee Brace

The DonJoy A22 Custom Knee Brace is one of the first titanium knee braces that’s custom made for your knee to ensure maximum knee protection. 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.

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 the components of the brace align perfectly with your body for maximum protection and comfort during movement.

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.

Product Questions

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.
Question by: Alam on Jan 7, 2016, 9:58 AM
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.

Is this the best answer as a brace played during football? I really like this brace and want to be able to use it during football season.
Question by: Christianq on Jul 15, 2016, 3:29 PM
No. The A-22 is not made for contact sports. You need something that is stronger and will withstand contact with other players. If you are wanting a custom brace you could look at the Defiance ll Custom Knee Brace.
Or if you are not wanting a custom knee brace, you could look at the Armor Knee Brace with Fourcepoint hinge

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?
Question by: Gary on Nov 27, 2015, 1:26 PM
Either brace will work for you but the A22 is lighter than the Defiance so if that matters to you then choose the A22

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.
Question by: Slava on Sep 11, 2015, 1:36 PM
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. The brace can be purchased here and then ou make an appointment to get your knee measured so the order can be placed

Does insurance cover cost
Question by: Marlon Naidoo on May 7, 2016, 11:15 AM
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
