DonJoy Performance Bionic Knee Brace – Hinged, Adjustable Patella Support, Lateral / Medial Ligament (ACL, MCL, LCL), Meniscus, Knee Sprains for Soccer, Basketball, Skiing, Hockey, Running, Water

30 years of using a metal brace, tried this to see if it would be as good and stop some of the muscle discomfort. Makes you feel like Steve Austin!

I absolutely love this knee brace! My right knee likes to dislocate and strain my mcl, this knee brace does a perfect job of keeping my patella in place and providing support for my knee. My knee is so bad now that it stays sore after extensive exercise aka riding and competing for me. When I wear this brace while riding there is no soreness after and this brace holds up fantastically to riding and weather! I’ve ridden in it in the summer heat, torrential down pours, freezing cold, etc. Never has this knee brace let me down and I’ve had it nearly a year! The metal side pieces are perfect for providing stability and support and I love this design for the Velcro. It stays out of the way of my saddle and stirrup leathers. I truly couldn’t have found a better knee brace, highly recommend!

Great fit - snug without being constrictive. Provides good support, handles perspiration well (doesn’t get loose). A tad expensive but I’d say it’s money well spent.

This bionic knee takes the pressure off and helps you walk. My right knee is shredded meniscus, ACL, PCL All gone. Can't afford surgery can barely walk downstairs. I've tried at least 10 different braces trying to avoid the three to $400 price tag for the god brace. This one I found and it actually helps. I can walk downstairs. It must be tight and it will stretch the more you use it. Measure your leg especially around the knees just as the instructions say before you order it and be sure it is tightly fitting. After a few days of use it will be very snug and it would be a little bit stiff to move but you'll be able to walk and that's what counts

I can't speak for any of the sizes other than Medium, but as others have said, do NOT depend on the chart for correct measurements. For reference, I have a 17-17.5 inch thigh (6" from mid patella), a 14" knee, and a 13" calf (6" from mid patella. Going by the size chart, I clearly fit into a Small. Didn't trust it, and ordered the Medium. Fits perfectly. My thoughts are that any measurements larger than mine, by maybe 1/2" or so might have a hard time getting the thing to wrap completely around the thigh and calf. That being said, it felt supportive, well made and as comfortable as a brace can be. I wouldn't rely too much on it preventing severe hyperextension - but it does seem to supply a decent amount of overall support and flexibility that will work for me.

After many years of kicking grown trees down and wrestling Silverbacks in the Congo, ive perfected the fighting art Muay Thai Kickboxing. I wear this when i need extra support, because all the tree kicking. Sometimes my leg might flex and bust free out of this knee prison, but is put back on to serve the time. I highly recommend this product, as it works wonderfully. I will take with me when i go to pet polar bears in the artic to enhance reflexive skills used in certain combat styles. Until then, stay safe and hone skills!
