Hi! My name is Emily, and I want to share with you my Donjoy story! I have a pretty unique story, and my Donjoy ACL braces play a vital role. Unlike sports such as soccer, basketball, volleyball, or skiing; my sport isn't one where your brand is yet represented by an athlete or even recognized. But nonetheless, I trust Donjoy's ACL braces to allow me to confidently continue in my favorite extreme sport in the whole world. Skydiving. Women make up only 13% of skydivers; I am one of those lucky few. I also overcame the odds of women with a multiple serious injury history who return to jump again. My injury history is pretty extensive. Prior to skydiving I had 4 ACL surgeries on my left knee. But during my first jump, I fell in love; literally FELL in love. Unfortunately my knees wouldn't love it as much. While landing my 11th jump I had my 5th ACL tear; this time on my right knee. I was devastated, because I knew from my prior 4 ACL tears what this meant. Another painful surgery, and another long stretch of frustrating rehab, and no skydiving. For someone as new in the sport as I was at the time, in addition to being a woman, no one expected me to return to the dropzone to skydive again. But I did. I kicked butt in therapy and 6 months later I received my bilateral pair of Donjoy ACL braces that my surgeon recommended if I insisted to continue skydiving. Nearly 400 jumps later I've earned an instructional rating in skydiving. I work as a coach at Jump Georgia Skydiving. I teach and train student skydivers, as well as being a mentor to new women entering our sport. I can't tell you how many times when visiting dropzones all over the country, that people have stopped me looking my legs to ask me for what I wear these 'bionic legs' and where I got them. That's where I share your brand most. I want to inspire people to not give up on something that makes them feel alive. To inspire courage, and banish defeat even after multiple injuries. That is what Donjoy has done for me. Helped me do what I love with confidence and banish defeat by not giving up simply out of fear that I could tear my ACL again for a 6th time. I don't jump without Donjoy, and I'd love to see your brand represented in my sport. Thanks for reading, and most of all thank you for keeping me in the sky! ”

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!”

~ Brooke Wohlers

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.”

DonJoy has provided relief and stability for me for over a decade now, and I can honestly say it is the best product on the market and the quality is superior. My DonJoy knee brace and I were inseparable after five knee surgeries to repair ACL and meniscus tears during my high school years. While these injuries shattered my dreams of playing collegiate and pro basketball, my faith in God and my determination to rehab properly, which included the use of my DonJoy brace, allowed me to continue to play the game I love throughout most of my high school years. God had other plans for my life, and I am living proof, at the age of 32, that you can overcome obstacles and come out stronger than you ever imagined possible. My advice to any one going through serious injuries and orthopedic surgeries is to pay attention to your body and err on the side of caution, regardless of the varying opinions you will receive from your medical team. My advice comes from experience, as my second ACL and meniscus tear came halfway through the basketball season when I felt I was getting stronger and competing at almost 100 percent. I made a decision to not wear my DonJoy brace in a game and sustained the injury, resulting in more surgery and rehab. Suffice it to say, I wore my DonJoy brace after the fifth surgery and still rely on their products to this day. While I no longer need the ACL brace, I will always have a DonJoy sleeve or other DonJoy product for stabilization and peace of mind. My knees are stronger now than in my early twenties. In fact, I am an avid runner and enjoy competitive running. Also, I never miss an opportunity to play a pick up game of basketball with friends. Prior to becoming sold on DonJoy, I tried another brace and there is honestly no comparison in the quality and stability the DonJoy product affords the user. The saying, you get what you pay for can truly be applied in my opinion of this other product. Spare no expense when it comes to a product like DonJoy that can give you your functionality back after a serious knee injury and provide you the quality of life that you deserve. My advice to all, whether you are a trained athlete or a weekend warrior, is to be smart and listen to your body. This is advice learned after pushing my limits. As an athlete, there is a fine line between pushing through the pain and taking care of an injury that could potentially define you for the rest of your life. DonJoy products work. Anyone ready for a run or a game of hoops? ”

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.”
