Product Questions

My thigh and calf measurements place me in the medium size range but my knee size does so in the large range. Which size would fit best?
Question by: Rick Garcia on Sep 19, 2010, 7:47 AM
Hello Rick,

Send us an email @ service@betterbraces.com with your measurements so that I can give a more accurate recommendation.

Is this brace good for me to play volleyball? i torn my acl, mcl, meniscus in 4 places, & sprained my pcl. Should i get another brace or this one?
Question by: Whitney on Jan 17, 2011, 5:12 PM
Hello Whitney,

The DonJoy Armor is a great rigid brace. If you want the same protection in a lighter brace, also check out the DonJoy Full Force Ligament Knee Brace.

I had a ACL repair but after playing soccer post rehab it got a little loose on me. Now when I play any type of dynamic sport my knee gets a little loose. What brace should I choose the full force. Defiance. The only dynamic sport I do now without instability is skiing. But I would like tp play soccer and b ball with my kids.
Which would be the best choice defiance, full force ?
Also what difference between rx braces and off the shelf. Thanks. Ken
Question by: Ken on Jan 3, 2011, 5:50 PM
Hello Ken,

The DonJoy Defiance is a custom knee brace that is built specifically to your measurements. Because of this, the Defiance will always be the best rigid brace we carry in support and ACL protection.

The DonJoy Fullforce is a great top of the line off the shelf brace (meaning sized like small, medium, large). This brace will add support and stability to the knee and help protect the ACL.

Neither braces will require a prescription.

Either brace will fit the application and activity level you described.

1. What is the difference in inches between the "standard" and "short" size?

2. What part of the brace is shorter on the "short" size, the part of the brace which is below the hinge or above the hinge?

3. I am purchasing the brace primarily to avoid knee hyper-extension ( PCL protection?). I see that in the "Knee Compartment" section above there are three options in the "Choose option..." box: ACL, CI and PCL. Does each of these represent a slight variation in the brace and if so, what are the variations?

Thank you.
Franz
Question by: Franz on Jan 5, 2011, 5:55 AM
Hello Franz,

1. 1 inch
2. Calf Cuff
3. The strapping sequence changes to address the ACL, PCL or both, (CI or combined instability)

I have an extreme bone contusion in my right knee on my Tibial Plateau. I am a serious wakeboard, and a high school pole vaulter. I am wondering about the support this brace will have on the bones in my knee? also i would like to know if it would prevent future bone contusions in my knee?
Question by: John Jacobs on Aug 31, 2013, 11:41 AM
You should look at the Armor and the knee guard attachment that would give you the most support and protetction, i would also recommend a sports cover for when wakeboarding.
