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.

    J brace patellar stabilzer

    Recommended by a Physical Therapist, I tried the J Brace. My patella was not tracking properly causing pain in many activities. The brace with the lateral knee J strap puts and keep the patella in the proper track for me. I'm back to all activities.

    J Brace Patellar Stabilizer Knee J-Strap

    Still getting used to the brace. Not quite sure if it is the right brace for me. I have a completely torn meniscus. The brace gives me really good support. The knee feels supported and restricted.Not sure about the straps. After a while of wearing the brace I tend to have sharp pains at the lower right side of my knee. Ive found the skinnier straps to loosen but they also bunch a little in the back of the knee. Definitely want to keep trying it. Hoping that greater use will get me more accustomed to the brace. Did golf 9 holes with it yesterday and had a pretty positive result. No additional pain until the 7th hole.
