Product Description

J Brace for Knee Support

Some might compare this J knee brace to the DonJoy lateral patella knee brace. Such J braces feature strapping mechanisms around the kneecap that help keep the patella in its proper position during movement. This, in turn, stabilizes the knee.

This J brace patellar stabilizer can help with the same types of ailments the DonJoy J brace treats. The knee J brace can help those dealing with patella subluxation or dislocation, patellofemoral syndrome and during rehab for patella tendon injuries. Like the DonJoy Lateral J knee brace, this brace can support an unstable knee and help with misalignment of the patella.

The J-strap knee brace does so thanks to a c-shaped buttress that helps the patella track as it should along with a four-part versatile strapping system. Two narrow straps are located just above and below the kneecap while two wider straps encircle the thigh and calf. The position and tightness of these straps can be easily adjusted as each has a buckle and fasteners.

The buttress can be moved to either the lateral or medial side of the knee or it can be removed altogether. This makes the J brace knee support useful for a variety of patellar tracking issues and at various stages of knee injury treatment.

The lateral J patella knee brace itself is constructed of premium-grade neoprene that is free of latex. The buttress of the J-sleeve knee brace is composed of compression-molded, textured neoprene. See more neoprene knee braces.

While this is not a hinged lateral J knee brace, it does come with stays for added support. These spiral stays also help the lateral J brace knee support from bunching or rolling. (You can find some hinged knee braces here.)

The DonJoy knee brace-like product can function as either a J brace for the left knee or a J brace for the right knee. It leaves the kneecap free of pressure and comes in a discreet black color.

Lateral J Brace for Patella Support

The primary function of J braces is to support the patella in a semi-rigid fashion via the flexible brace material and a lateral j-style strap mechanism. Besides the dynamic strapping, the c-shaped buttress of this lateral knee brace also helps the kneecap track as it should.  

Stays on either side of the knee provide additional support and limit harmful movement of the knee.

Wearing a J-brace with all of these features helps the patella stay in its proper position anatomically speaking during movement. This helps reduce pain and improve movement of the kneecap. Stabilizing the kneecap via a patellar stabilizer like this also protects against further worsening of an injury.

The neoprene knee sleeve of this J buttress knee brace is also beneficial for injury treatment in that it provides compression and warmth to the knee joint. Compression can help reduce inflammation and promote healing. And warmth can help with joint stiffness.

The brace can also help with recovery from lateral release knee surgery and after a meniscometry. Muscular imbalances, structural abnormalities and force are just a few of the things that can cause the patella to track toward the outer part of the body or to patellar lateralization where the patella resides outside of the middle of the kneecap.

In some cases, rehab to correct muscle imbalances and taping the knee and/or wearing a brace aimed at correcting patellar tracking can do the trick.

But in other instances, knee surgery lateral release may be needed to correct the maltracking and realign the knee cap, especially if patella dislocation is a recurrent event. Patella lateral release is most effective for those with an excessive tilt to the kneecap. (See our knee braces for patella dislocation.)

Lateral release of the patella is a procedure where a surgeon cuts through a retinaculum (a tight tissue attached to the outside of the kneecap) that is too tight, allowing the kneecap to move back into the groove in which it is supposed to reside.

Great support

First, I was very impressed with the shipping. When I ordered it the estimated shipping was 5 days which is pretty fast, but it came in 3 days so I was very pleasantly surprised. So far I've worn it for a day, but it's been quite comfortable, and very supportive. I bought this because I suffered a dislocated kneecap and when I try to walk my knee feels weak and unstable, but this brace gives full support and makes me feel safe while walking. I've never used a brace before, so I wasn't sure about the material since the neoprene is supposed to be warming, and I was worried it might mean lots of sweating and being too warm, but it's super comfortable. It's a nice subtle soothing warmth- it's like my knee is getting a nice hug. The J strap is fully removable so you can adjust it to weather is most comfortable which I really like. Again it's super supportive, my kneecap feels stable and supported with it on. The only thing is that the seam at the back mildly irritates the back of my knee, but I only felt it once when I was sitting on the floor with my knee bent so it kind of bunched up at the back, and when I took it off I could feel were the seam had irritated the back of my knee but the sensation went away pretty quick. Easy solution is just a sleeve underneath to protect the skin from the seam, so I'm not concerned about it. Overall I'm very pleased with this brace, especially since it was comparably cheap to similar ones from other brands.


Product always here before I know it.

I used it upon receiving it and it did something wasn't expecting. After walking a few yards it slide down my leg even though I tighten it. Thought maybe was too large but my thighs are very large where it should have stayed up. Will continue to try and wear if not have t send it back.

Not what I expected for the price.

Bought this for my daughter who plays on a competitive travel fastpitch softball team. Concept was good and provided good support after many consecutive hours of play. Prevented fatigue well. Quality is not durable enough to hold up to vigorous activity though. The J buttress is very poor quality and design and wears out quickly even with mild conditioning in the gym for basketball. We are changing to a different product.

immediate relief

I had pain in my entire leg from an injury to my knee. This brace is easy to put on, adjust and take off. I had no problems sleeping in it as my MD recommended. I feel more secure walking and moving with it on. I also noticed after wearing it over night I had much less swelling. I love that it is light weight, made well and the company was very easy to work with, also made in America.


Carol, We are so happy to hear that the J brace was the knee brace for you! Hopefully your knee won't be slowing you down on those walks anymore. Thank you for taking the time to tell us how it helped you, I know others will appreciate it as well. Tara -BraceAbility Customer Care
