The Donjoy Lateral J Patella Knee Brace stabilizes the kneecap to prevent dislocations and alleviate pain. The patella tracker controls the kneecap using a flexible tubular buttress insert that runs alongside the knee, and provides support against lateral patellar subluxation, dislocations, or improper patellar tracking. The bifurcated tension strap direct forces medially providing inferior and lateral patella stabilization. Tracking is improved and stress on the underside of the kneecap is reduced with day-to-day activities like walking or climbing stairs.
The brace features a unique patented nylon core/polyester Lycra fabric for comfort, and allows for improved airflow while still giving ample support and compression. The product has spiral stays on the sides to help it maintain its shape and not roll down during activity. It's available in standard Neoprene or breathable Drytex material for use in warmer climates.

Challengingto find this now
This brace is very challenging to find online now - glad I was able to find it through DME-Direct. I've been wearing this same brace for the last 10 years and it helps my kneecap track correctly so I don't feel pain when I go hiking or do other activities outdoors with my family.

Helps my kneecap issue
The brace is great and I got the Drytex version because I live in Florida. I use the brace with hiking and jogging because these are the types of sports where I typically feel the pain around my kneecap area. This brace stabilizes my knee and takes away the sharp pain that I used to feel.
Great support
Great brace for patellar instability. DME Direct customer service was extremely helpful. Fast shipping.

Thank you for the kind words. Glad to hear the brace is helping!
Fabric ripped after wearing only 6 times.
Ordered a left and right brace for my daughter for volleyball. After only wearing them six times both braces were worn and ripping. DME replaced them for free.
Excellent brace!
Just like the one we got from therapy that cost a $100's more! Fits well, great price! Can't ask for more!

Helpful For My Knee Cap Dislocation
I bought this about 7 months ago because my knee cap is very loose and tends to sublux easily. I didn't have surgery and tried some other braces from McDavid and Mueller but didn't find them to be supportive enough with my running. I was able to get the J buttress to scoot in tight right next to the lateral side of my knee cap and provide control and peace of mind. I used my Lateral J knee brace whenever I play basketball or go on runs - I'm still careful but much less cautious with the brace.
Good Design But Could Be Better
It's a good brace in terms of support. I found the seam in the back starting to irritate my skin after wearing for more than two hours. You might have better results.
Great Brace
After dislocating my knee cap while surfing, I wore another brace that was difficult for me to move in, more restrictive. This is the most comfortable brace I've ever worn, and I'm able to go to physical therapy and participate in exercise without fearing my kneecap is going to dislocate again. Thankyou!
Drytex Is Very Comfortable
I got the Drytex version because I use this primarily for triathlons here in Arizona was it's terribly hot. The Drytex material is comfortable and breathes well. The buttress design is durable so that you can really pull on the straps to get the patella to feel stabilized without fearing that they'll rip out of place. This is my second Lateral J from Donjoy and they work pretty well for my needs.
