Product Questions

How long should the OA Nano Brace Last? I have worn My Brace Daily for a little 13 Months, and the Metal Frame has Broken. The Frame that Cover the upper Thigh has Fatigue Cracked and it totally separated. Would l=this be covered under Warranty? I like the Brace, and it really helps to reduce the swelling and Inflammation.
Question by: Greg on Feb 28, 2015, 5:58 AM
Although the OA Nano has a one year warranty on the frame and hinges the frame should not have broken after such a short period of time. Please call me at product support 888-405-3251 so I can arrange a replacement. And get your brace sent in to us.

I have had a lateral release and 3 scopes to remove loose cartilage, especially on the back of my knee cap. After the third scope which was 12/2012 my knee hasn't recovered as it has in the past. Pain across the front of the knee, the outside, and the inside of the back of the joint that the doctor tells me it is due to the swelling that occurs when I engage in physical activity. It also hyperextends and gives out on me from time to time, and is showing the beginning signs of OA. Which brace would you recommend for me? Thanks in advance.
Question by: Matt on Jun 7, 2013, 1:59 PM
Hello Matt,

Do you have medial or lateral OA or Both? Find out from your Physician which meniscus is affected.

An OA Brace is not recommended for someone who has Bilateral OA. It would cause more pain. Since, an OA brace shifts the weight from the affected side of the knee to the healthy side.

If you are not a candidate for an OA Brace I recommend a Soft Hinged Brace or a Rigid knee Brace.

See Below.

For additional questions please call a Product Specialist at 1-888-405-3251.

I have a partial tear in my ACL, and I'm wondering of this brace will be a good option for post ACL surgery?
Question by: Andrew on Jul 12, 2016, 2:40 PM
The OA would not work for you as it’s a osteoarthritis brace, you could use a our DonJoy TROM Advanced, which would help for your post-surgery , or if you’re looking for something for after surgery once your cleared for activity you would want to take a look at our Defiance Knee Brace. Please see links below:

I have the DonJoy OA Nano Knee Brace which my doctor recommended I use after my second knee surgery this May. It does help a lot with my walking. I do want to know if the brace is water proof. I was reading all the information about the brace and it doesn't say if I can get the brace wet.

Thank you
Question by: laurel on Jun 16, 2013, 1:28 PM
Hello Laurel,

Yes, you can use the brace in water. We recommend you rinse the brace each time you exit the water.

Thanks for contacting Donjoy.

I am a MRI Technologist. Can the uploading brace be worn while working in the MRI suite? I need to find out if all of the materials are MRI safe. This in reference to working in MRI, not having a MRI.

Question by: MRI gal on Jan 15, 2015, 12:57 AM
There is metal in the brace so you will have to go by your protocols for that specific MRI machine that you have in place at your facility
