A compression knee sleeve wraps the knee in a layer of elastic fabric that applies consistent, even pressure around the joint. That pressure keeps the surrounding tissue snug during movement, which many people find useful for day-to-day knee comfort. Unlike a rigid brace, a sleeve does not restrict the range of motion or lock the joint in place. It moves with you.
Sleeves vary in material composition, thickness, and whether they include any additional features beyond basic compression. The two options we carry reflect that range well. One is a straightforward undersleeve designed primarily as a skin-protecting layer to be worn under a knee brace. The other incorporates medicine directly into its fabric for a more targeted approach to knee comfort.
Patellar Compression Sleeve: Open vs. Closed Patella
One detail worth understanding before buying is the patellar design. A patellar compression sleeve with a closed patella cover completely covers the kneecap, distributing pressure evenly across the entire joint. An open patella design features a cutout over the kneecap, reducing direct pressure on that area and providing a more comfortable fit for people who notice discomfort at the front of the knee during wear.
The products in our lineup use a closed patella design, which suits most everyday users. If you have a specific preference or your care provider has recommended patella coverage, reach out to our team before ordering.
Compression Knee Sleeves At Ortho Bracing
We carry two knee sleeve options at Ortho Bracing. Here is a detailed look at each.
Nufabrx Pain Relief Knee Sleeve
The
Nufabrx Pain Relief Knee Sleeve is a compression knee sleeve with an added feature that sets it apart from standard sleeves: medicine is woven directly into the fabric at key contact points. The sleeve is made from 93% nylon and 7% spandex, and during wear, the embedded capsaicin-based formula activates on skin contact.
To work as intended, the sleeve must be placed directly against the skin. Other clothing can be worn over it. It does not require electricity, patches, or topical creams applied separately. The compression component functions as it would in any standard sleeve, applying consistent pressure to the joint throughout the day. The embedded medicine remains effective for up to 15 washes, after which the sleeve continues to function as a standard compression sleeve.
The Nufabrx is made in the USA and carries a money-back guarantee. It fits a thigh circumference of 17 to 21.5 inches, measured 5.5 inches above the top of the kneecap.
Key features include:
- 93% nylon, 7% spandex construction
- Capsaicin-based medicine embedded into the fabric at key contact points
- Activates on skin contact; must be worn directly against the skin
- Effective for up to 15 washes
- Can be worn under clothing
- One size fits most; thigh circumference 17 to 21.5 inches
- Made in the USA
- Machine washable in cold water
DonJoy Undersleeve Cotton/Lycra For Knee Braces
The
DonJoy Undersleeve Cotton/Lycra is a compression sleeve designed primarily to be worn beneath a rigid or semi-rigid knee brace. Its purpose is practical: it creates a comfortable barrier between the skin and the brace frame, preventing chafing, reducing abrasion, and managing moisture during wear.
Made from 86% cotton and 14% Lycra, the sleeve is soft, lightweight, and breathable. The tapered design keeps it in place without relying on rubber, latex, or elastic bands, making it a good fit for people with skin sensitivities. It is easy to apply, fits either leg, and comes in multiple sizes based on thigh circumference measured six inches above the center of the knee.
While it can be worn on its own, this undersleeve is primarily intended to improve the experience of wearing a knee brace. Customers who wear hinged or rigid knee braces daily often find that extended wear is significantly more comfortable with the undersleeve in place. Buying a pair is practical, so one can be washed while the other is in use.
Key features include:
- 86% cotton, 14% Lycra construction
- Designed to be worn under a rigid or semi-rigid knee brace
- Reduces chafing, abrasion, and skin irritation from brace hardware
- Tapered design reduces migration without rubber, latex, or elastic bands
- Not made with natural rubber latex
- Fits left or right leg
- Multiple sizes available
- Machine washable
Knee Sleeve vs. Knee Brace: Knowing The Difference
A question worth addressing directly is the difference between a knee sleeve and a knee brace, since the two are often considered alongside each other.
A compression knee sleeve applies even pressure around the joint and moves freely with the leg. It provides no structural restriction and does not limit the range of motion in any direction. It is the lighter-support option, suited for everyday wear, lower-impact activity, and situations where comfort and compression are the primary goals.
A knee brace, particularly a hinged model, provides structural support through rigid or semi-rigid components that limit side-to-side movement. It is the more appropriate choice when lateral stability is the priority, such as during recovery from a procedure or when a care provider has specifically recommended bracing. Our full range of
knee braces and sleeves covers both categories, so you can compare options side by side.
The DonJoy Undersleeve sits at the intersection of these two categories. On its own, it functions as a light compression sleeve. Paired with a knee brace, it improves comfort when wearing it for extended periods. For a broader look at our knee sleeve inventory specifically, our
compression sleeves for knee support collection is the right starting point.
Knee Sleeve For Running And Active Use
A knee sleeve for running needs to stay in place through movement, manage moisture, and add support without restricting stride. Both sleeves in our lineup hold their position during activity, though they suit different situations.
The Nufabrx sleeve is the more active-forward option of the two. Its nylon-spandex construction stretches and recovers well, and the compression it applies is well-suited to lower-impact activity like walking, light jogging, or extended time on your feet. The DonJoy Undersleeve, while functional on its own, is designed with under-brace use in mind and performs best in that role.
If you are primarily looking for a sleeve to wear during activity without a brace over it, the Nufabrx is the more direct fit. If you wear a rigid brace during activity and want to make it more comfortable to use for longer, the DonJoy Undersleeve is a practical addition to your setup.
Knee Sleeve For Arthritis And All-Day Wear
A knee sleeve for arthritis use typically comes down to comfort, ease of application, and how well it holds up throughout a full day of wear. Both products in our lineup address this, though from different angles.
The Nufabrx sleeve combines consistent compression with its embedded formula, making it a one-piece option for people who want knee coverage and the benefit of its medicine-infused fabric in a single garment. The sleeve goes on like any standard sleeve and can be worn under everyday clothing without being noticeable.
The DonJoy Undersleeve, with its cotton-dominant fabric, is particularly gentle on sensitive skin. The absence of rubber, latex, or elastic bands makes it a lower-irritation choice for people who react to those materials. Its soft construction means it can be worn for extended periods without the skin fatigue that sometimes comes with denser compression materials.
Consult your healthcare provider before incorporating any compression sleeve into your routine.
Sizing And Pairing Your Sleeve With Other Supports
Sizing is straightforward for both products, but the measurement method differs slightly.
For the Nufabrx knee sleeve, measure your thigh circumference 5.5 inches above the top of your kneecap while standing. The sleeve fits a range of 17 to 21.5 inches. For the DonJoy Undersleeve, measure 6 inches above the center of the knee, then refer to the sizing chart on the product page, which covers several thigh circumference ranges across multiple sizes.
If you wear a rigid knee brace with a compression sleeve, the DonJoy Undersleeve should match the brace's sizing. Pairing a large brace with a mismatched undersleeve reduces the protective fit that the undersleeve is meant to deliver.
Many people also use knee sleeves alongside cold therapy as part of a broader at-home routine. Our resource on
cold therapy for knee pain covers the available options. For those also managing support needs in other areas, our
back braces and supports collection has options worth reviewing. Our
DonJoy knee products page covers the full range of DonJoy options we stock, including sleeves.
