I tore my ACL last year during an 8th grade basketball game for my club team, The Panthers. A year later, I got my DonJoy knee brace and made both the JV and Varsity team at my high school as a freshman! My brace gives me the confidence and support I need to play my best game. I named my brace "Joy" and just like my rep told me, I can't imagine playing without her. I'm playing soccer in the Spring and know my brace will give me the extra confidence I need to make the varsity team! Thank you for making a brace that is both functional and comfortable. It's like second nature to wear it!

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.

I just wanted to thank you all very much. I served four years in the USMC in the infantry, and I completed 2 combat tours (Iraq and Afghanistan.) While in Afghanistan our constant patrols and strenuous missions took a tool on my knee. I got out in 2011 and the VA was quick to operate on my knee. However, it only made my pain worse. I've suffered with severe pain and limited activity for 3 years. I'm thankful to now be able to keep up with my children and their active lifestyles. My family and I thank you for your great product (I've been through enough to know a great one when I find one.) Semper Fi.
