"1. WOW! The pain is gone as soon as I put them on. When we decided to go to the braces, my doctor told me that many people don’t wear them because of the bulk and visibility. “They aren’t very effective when they sit on the shelf.” I am not finding it difficult to wear them since the inconvenience PALES in comparison to the pain relief when wearing them.” 2. What took me so long to agree to these? If only I knew then what I know now. I want to shout from the rooftop to all those people struggling with the decision to make the financial investment and to commit to the inconvenience. Count me in as a true believer! My only suggestions for improvement: Alter the design such that the brace can be removed without removing shoes and pants. Can both the bottom and top be on the same side? I travel frequently, the braces set off the metal detectors at the airport. Can they be constructed of another material that won’t do that? "

"At first this hurt the inflamed side of my knee that the extra pressure was on. But now in about a week I have no pain at all when I wear it. The DonJoy Defiance is so light that exercise is very easy and it doesn't through me off balance at all. My only complaint is where to find pants that can be worn over it with it sticking out. I finally bought a couple of skirts because this definitely doesn't work under jeans."
