Custom Defiance III - Excellent!

Very pleased with my custom Don Joy Defiance III unloader brace. I've been able to delay a knee replacement for two years (so far) by wearing it. It holds my knee (and leg) together so securely that I am essentially pain free. I don't hesitate to go up or down stairs and I don't experience the swelling and fluid build-up in my leg that I had before the brace. Eventually I may have to replace the knee, but I found the ordeal so unpleasant when I had the other one done that I'm in no hurry to go through it again. Many thanks for designing such an effective brace.

Thank you for your 5 star review.
I would buy another

Great and sturdy walking 7 days out post surgery.
