Hey wanted to give you feedback. I am a walking ad for DonJoy! I've been to 3 elite lacrosse tournaments and I wear the Trizone cuz I walk and stand all day. I've had a handful of people at each one ask about it! I've been wearing the reaction one too when I run. Everyone that asks me I point them to your site. Anything else I can do to get a better word out there. I really have had a lot of people ask. You know we only "hang" with the sporty over 40 and they all have knee probs!!! Glad I have DJ stuff cuz it really does help. I'm not sore at night like I usually am.

I've had my DonJoy for about 10 years due to some medial meniscus issues. It has always brought immediate relief as soon as I put it on but I learned just how strong it was this week when I fell off a scooter while wearing my brace in Panama. I was wearing my brace as I always do on long-walking days (thankfully) and as I crashed into my left leg, the one with the DonJoy, the brace almost completely protected my entire leg of injury. I have one scratch on the part of my knee that wasn't covered but that's it! Now I know this isn't the purpose of the brace, but not only did it break my fall, protect my leg, it also didn't break. I’ve worn it every day since and have a whole new appreciation for the brace. 10 years old, 1 scooter crash, and it's as great as the day I got it, other than some new, gnarly scratches. Cannot recommend this brace more.

I have always wanted to climb Mount Kilimanjaro and decided this was the year. I spent multiple months training and preparing to summit the "Roof of Africa" when I tore my medial meniscus just weeks before realizing my dream. The MRI also showed I have grade 3 degeneration of the cartilage in my right knee, this was a result of surgery on my ACL&MCL 20 years ago. Needless to say, I was in shock about the diagnosis. I spoke with my orthopedist and he recommended I speak with a DonJoy representative about the situation. The OA Nano knee brace was recommended to help with my osteoarthritis and meniscus, so I gave it a shot. I was surprised how light and durable the OA Nano with the magnesium frame was, but more importantly the stability it provided my knee. This gave me a renewed confidence, so I boarded the plane for Tanzania. My tour group and operators were incredibly supportive and the OA Nano was with me every step of the way – literally – on my grueling 6-day trek to the summit and back. In the end, the journey was even better than I could have ever dreamed of.
