DonJoy Performance Bionic Knee Brace (Black, Medium)

Excellent product, for what it is and purports to be. I have a torn medial meniscus, patellar malalignment and osteoarthritis in my left knee. Before I got this brace, climbing and descending stairs was very painful and my knee felt very unstable just when I walked on flat ground. After about three weeks of wearing this brace at all times except when I sleep and shower, I can now walk and climb and descend stairs pain-free, so long as I’m wearing the brace. In fact, I’ve done a couple of 10-mile moderately difficult hikes wearing it, with no pain. And I can now ride a bike. It’s not a $500 Unloader Brace, so I don’t know that continuing to wear it is going to enable any of my conditions to heal. But it does provide some vertical support, and regular use of it for 3 weeks enabled me to return to my usual low impact activities. While I’m wearing it I no longer have pain or instability. I’m 67 and don’t do high impact activities anymore, so I don’t know whether it would enable me to do them. Sizing: Based on the size guide on Amazon, I bought a Medium. On my bare leg it fits perfectly, and comfortably. But it’s too small to enable me to put it on over jeans or any but the thinnest pants. So you may want to order up a size.

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!

Material seemed to be of good quality. It does slip down a little.But I think most of them will anyway.

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!

Bought this for the hyper flexion in my knee and it helps somewhat. Not as good as advertised. Also was very careful and measured like they said and bought the recommended size but it’s actually too small. I would recommend a size bigger than what the chart suggests.

This is a good brace. The best part is that it does not ride down the leg while in use (most of the time). The only time it does is when the velcro buckle which is pretty thick and durable grabs onto a pair of pants being put on over them and therefore unbuclkles the strap. I have gone through many braces and this one stays in place. I have also sent 3 others back before settling with this one. I do have to laugh at some reviews on braces about how they are too tigh or not supportive enough only to see a picture of a heavy set person wearing crocs or flip flops. If you are someone of significant size do yourself a big favor and wear proper foot wear. Your knees will thank you as well as your ankles. Those sandle designs are for kids.

I ordered this knee brace on February 26 2025 it's 16 months old and falling apart I texted the company and emailed them their not set up for chat I've had braces that lasted years. I would not buy their products. You can't get a hold of them

Comfortable and effective.

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!

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.
