Ossur Unloader One X Knee Brace – Clinically Proven Relief for Knee Osteoarthritis, Bone-on-Bone Pain & Meniscus Tears

The Ossur Unloader One X is the gold-standard unloader knee brace for patients with unicompartmental knee osteoarthritis (OA), bone-on-bone knee pain, degenerative meniscus tears, and related conditions. Using Össur's patented 3-Point Leverage System and SmartDosing™ dials, it biomechanically shifts load away from the damaged compartment — delivering measurable, adjustable pain relief without surgery.

🦵 How to Choose the Right Unloader One X for Your Knee

This brace comes in several versions. Answer these 4 quick questions to find your exact match — or share your prescription with us and we’ll confirm your selection.

Step 1 — Which knee is painful?

Right Knee
→ Choose Right
Left Knee
→ Choose Left

Step 2 — Where is your knee pain located?

Stand with your feet together. Look at your painful knee.

Pain on the INSIDE of the knee
(toward your other leg — the most common type)
Your knee may bow inward (varus / bow-legged)
→ Choose Medial
Pain on the OUTSIDE of the knee
(away from your other leg)
Your knee may bow outward (valgus / knock-kneed)
→ Choose Lateral

💡 Not sure? Check your X-ray report or ask your doctor — it will say “medial compartment OA” or “lateral compartment OA.”

Step 3 — Standard or Short frame?

Standard
Full-length frame. Best for most patients. Recommended for active use and maximum stability.
Short
Shorter frame. Better for shorter legs, patients with sensitive skin behind the knee, or those who find the standard frame uncomfortable.

💡 If your doctor prescribed a specific frame length, follow their recommendation. When in doubt, Standard is the most commonly prescribed.

Step 4 — What is your thigh circumference?

Measure around your thigh 6 inches (15 cm) above the center of your kneecap while standing. If you are on the border between sizes, we suggest you move to the next size up, especially if you have frequent swelling.

Size Thigh Circumference Part Number Examples
XS – M 13–19"
(33–48 cm)
UOX0518713, UOX0618713, UOX1518713
L – XL 19–26"
(48–66 cm)
UOX0518715, UOX0618715, UOX1518715

📋 Quick Reference: Variant Name Decoder

Each variant name follows this pattern: [Frame] [Side] [Compartment] [Size]

Example: "Standard Right Medial XS-M" = Full-length frame · Right knee · Inside pain · Smaller thigh

Example: "Short Left Lateral L-XL" = Short frame · Left knee · Outside pain · Larger thigh

Still unsure? Your prescription or fitting notes from your doctor or physical therapist will specify the exact variant. You can also contact us and we’ll help you confirm the right choice.

Frequently Asked Questions

What is knee osteoarthritis and why does it cause bone-on-bone pain?

Knee osteoarthritis (OA) is a degenerative joint disease in which the articular cartilage — the smooth cushioning tissue that covers the ends of the bones — gradually breaks down. As cartilage wears away, the space between the femur (thigh bone) and tibia (shin bone) narrows. In advanced OA, this cartilage is completely gone, causing the bones to rub directly against each other — a condition commonly called “bone-on-bone.” This produces pain, swelling, stiffness, and reduced range of motion, particularly with weight-bearing activities like walking, climbing stairs, or standing for extended periods.

How does an unloader knee brace actually relieve OA pain?

An unloader brace works by applying a controlled three-point bending force to the knee, which shifts the mechanical load away from the damaged compartment and onto the healthier side of the joint. The Ossur Unloader One X uses a patented 3-Point Leverage System with SmartDosing™ dials to precisely control the amount of offloading. Clinical studies have shown that properly fitted unloader braces can significantly reduce pain, improve function, and delay the need for knee replacement surgery in patients with unicompartmental OA.

Can an unloader brace help me avoid or delay knee replacement surgery?

Yes — for many patients with unicompartmental OA, an unloader brace is a proven conservative treatment that can significantly delay or even eliminate the need for knee replacement surgery. Multiple peer-reviewed studies have demonstrated that consistent use of an OA unloader brace reduces pain, improves activity levels, and slows disease progression. Orthopedic surgeons frequently prescribe unloader braces as a first-line non-surgical intervention, particularly for younger or more active patients who want to remain active while managing their OA.

What is the difference between medial and lateral knee OA, and how do I know which I have?

The knee joint has two compartments: the medial (inner) compartment on the side closest to your other leg, and the lateral (outer) compartment on the outside. Medial compartment OA is by far the most common, often associated with a varus (bow-legged) alignment. Lateral compartment OA is less common and typically associated with valgus (knock-kneed) alignment. Your doctor’s X-ray report or prescription will specify which compartment is affected — look for the terms “medial compartment OA” or “lateral compartment OA.” Choosing the correct medial or lateral version of the brace is critical for effective offloading.

Can I wear the Unloader One X during sports and physical activity?

Yes. The Ossur Unloader One X is specifically designed for active patients and is one of the most activity-friendly OA braces available. Its low-profile frame, anti-migration calf strap, and SmartDosing™ tension control make it suitable for walking, hiking, cycling, golf, and other low-to-moderate impact activities. Many patients report being able to return to activities they had abandoned due to knee pain. Always consult your physician or physical therapist regarding appropriate activity levels for your specific condition and stage of OA.

NO REGRETS NO FRETS 🙂
Size: 2 Ounce (Pack of 1), Color: Tallow
Love it. Nothing bad. Soft, creamy, absorbs amazingly well, no odor, does wonders for back of hands from frequent hand washing, can fill a crack in skin with the tallow to heal a dryness related wound. Wash hands dry and the warm water and some soaps can strip skin oil and use this tallow to seal and/or replace moisture in your hands! No greasy issues. Truly a lifetime pick and my jar has easily another month usage and had it so far at least two months. Just a dab on back of palms and rub and work up on forearm and elbow. You will not be disappointed using it. I keep near the sink to remind me 🙂

My new favorite moisturizer
Size: 2 Ounce (Pack of 1), Color: Tallow, Size: 2 Ounce (Pack of 1), Color: Tallow
This is the best moisturizer I’ve ever used on my hands. I struggle with dry hands in the winter from the cold and constant handwashing, so I’m always having to put moisturizer on to combat the dryness. My fiancé had started using beef tallow on his face (another more expensive brand) and was raving about it so I went searching on Amazon to get my own bottle. I chose this one based on the ingredients and the good reviews, as well as the price point. I love the way it melts into your hands leaving them silky smooth with no residue, greasiness, or stickiness. The reason that I deducted one star was because I felt the advertisement on Amazon was misleading. If you read the headline it makes it sound like the product has all organic ingredients. When I read the ingredient list once I received the product, the only ingredient that was listed as organic in the formula was the beeswax. I still love the product and I already bought another bottle, but I thought it was worth mentioning as I know that using 100% organic products is important to some people. I still highly recommend this product based on its effectiveness.

My skin feels nourished and radiant ✨
Size: 2 Ounce (Pack of 1), Color: Tallow
I’ve been using this balm for a little while now, and the difference is subtle but real. The texture is incredibly smooth and melts easily into my skin without feeling greasy. I can tell it’s made with really high-quality ingredients because it absorbs beautifully and leaves my skin feeling nourished immediately. Since I started using it, the areas that usually feel dry—my hands and the sides of my face—are softer and more supple. Even the little cracks and rough patches have improved, and my skin looks and feels renewed and radiant. It’s not an overnight transformation, but it’s a steady, noticeable change that makes my skin feel healthy and cared for. What I love most is how it strengthens my skin barrier. My skin feels more resilient and comfortable throughout the day, even in dry or cold weather. It’s like it quietly restores balance and keeps my skin happy without any heaviness or stickiness. Using this balm has made my daily skincare feel a little more nurturing and confident—my skin looks smoother, softer, and truly glowing 🐝💛
