What Our Customers Are Saying?

Alicia., 67

"This is honestly one of the best knee braces I’ve ever used. I have osteoarthritis and occasional knee pain, and I really like having the red light and infrared therapy combined with the built-in massage."

David L., 72 — 3rd Knee Surgery

"I've done this recovery twice before, so I know what a bad one feels like. This was the easiest of the three by a mile. If you're facing this surgery, don't do it without this. That's my honest opinion after three knee surgeries."

Susan K., 58

"I cried after my first three PT appointments. I'm not exaggerating — I told my husband I couldn't do it anymore. My daughter-in-law found RedRelief and I was so skeptical, but at that point I would've tried anything. I started using it 20 minutes before PT to loosen the joint and 20 minutes after to calm the swelling. Within a week, PT stopped being torture. My therapist actually asked what I was doing differently. I hit 130 degrees at week 10 — my surgeon's goal was 120 by week 12."

How Does RedRelief™ Help Knee OA?

Red and near-infrared light therapy is one of the most-studied drug-free options for knee osteoarthritis. Clinical reviews link it to less pain and better function, especially alongside exercise.

Calms joint inflammation.

Light therapy (photobiomodulation) helps cells manage oxidative stress and regulate inflammatory signals. Think cellular signaling, not just a light therapy pad.

Eases pain and stiffness.

Near-infrared light reaches deep into the joint area, while gentle warmth relaxes tight muscles around the knee.

Studied for decades.

Over 30 years of research on light therapy for knee pain, including randomized trials and meta-analyses in knee osteoarthritis.

Gentle and drug-free.

Non-invasive and low-energy, with no pills and no needles. A comfortable option alongside your current treatment.

Knee Arthritis Isn't Just Pain. It's Everything It Takes Away.

For most people it isn't a dramatic flare. It's a constant, grinding ache that never quite leaves. Some days are a stitch worse. Most days are just hard.

The first few steps after you've been sitting. Getting out of bed. Gripping the rail on the stairs. Standing in a queue and feeling your knee seize after ten minutes. Lying awake because no position stops the throb. Cold mornings that make it all worse.

You've tried the usual things. Paracetamol. Ibuprofen gel that "helps a little." Hot packs, ice packs. Maybe injections that work for a few months, then wear off. Maybe you can't take anti-inflammatories at all because of your blood pressure or your stomach.

And quietly, the list of things you've stopped doing grows. Long walks. Aqua aerobics. Gardening. Keeping up with the grandkids. You feel older than you are.

If that sounds familiar, you're not alone, and you're not weak.

Here's what's happening. As cartilage wears thin, the joint lining becomes irritated and inflamed. Fluid builds up, the muscles around the knee tighten to guard it, and circulation slows.

That starts a cycle. Pain makes you move less. Moving less weakens the muscles that support the knee and makes it stiffer. A weaker, stiffer knee hurts more.

The frustrating part? Movement is what helps. Almost everyone with knee arthritis says it: once you get going, the pain eases. It's getting started that hurts.

That's where RedRelief fits. Not to replace your doctor, your exercises or your current treatment, but to calm the ache and loosen the knee so getting started isn't the hardest part of your day.

Told You'll Need a Knee Replacement "Someday"?

Maybe you're on a waiting list that runs for months. Maybe you've been told you're too young, or need to lose weight first. Or maybe you're just not ready to face the surgery and the recovery.

Whatever the reason, you're waiting. And the waiting hurts.

RedRelief gives you something to do in the meantime: a daily routine that eases the ache and stiffness so you can keep walking, keep your leg muscles working, and keep living your life.

Staying active before surgery matters. Ask your surgeon or physio about strengthening exercises you can do now; RedRelief can make them easier to stick with.

And if you do have surgery, RedRelief comes with you into recovery.

20 Minutes, Morning and Night. That's the Whole Routine.

Consistency is what makes light therapy work. Two short sessions fit right into the times your knee hurts most.

20 minutes BEFORE you get out of bed:

Warms and loosens a knee that stiffened overnight
Takes the edge off those miserable first steps
Gets blood flowing before stairs, errands or a walk

20 minutes at NIGHT, in bed or on the sofa:

Calms the ache that builds over a day on your feet
Relaxes the tight muscles guarding the joint
Helps you settle down instead of lying awake with a throbbing knee

Extra session when you need it: before a day of standing, shopping or travel, or on cold days when your knee is worse.

Start gently: in the first week, use Mode 1 for 10 minutes, then build up to 20. Relief often builds over the first few weeks of daily use, so give it at least 8 weeks.

RedRelief doesn't replace exercise, physio or your doctor's plan. It makes them easier to stick with.

Move With Less Pain and Stay Active for Longer.

Here's something most people with knee arthritis don't realize: the tissues around your knee are working hard every day to cope with wear.

The bottleneck isn't just the joint itself. It's the environment your cells are working in.

In an arthritic knee, the joint lining is irritated, circulation is sluggish, and the muscles that support it stay tense. Your mitochondria, the "power plants" inside every cell, struggle to keep up. Everything runs at half speed.

It's like running an engine on old oil. It still works, but it grinds, heats up and wears faster.

To help, three things need to happen:

PENETRATE. The light has to reach the joint area. Near-infrared light (850 nm) passes through skin into deeper tissue around the knee.
ENERGIZE. That light is absorbed by the mitochondria, giving cells extra energy to work normally.
CALM. Inflammation settles, circulation improves, and the ache and stiffness ease.

Miss one, and relief stays shallow.

That's why pills fall short: they dull the pain for a few hours but do nothing for stiffness, and many people can't take them every day.

Why gels fall short: they "help a little," but barely reach past the skin.

Why a heating pad falls short: surface warmth, no deep light, no cellular effect. You want all three steps, from one wrap you can wear at home.

What the Research Says About Red Light & Infrared Therapy for Knee OA

Red light therapy isn't new-age wellness. It has been studied for knee pain for more than 30 years. Red (660 nm) and near-infrared (850 nm) light are absorbed by your mitochondria, which can increase cellular energy (ATP), help regulate inflammation, and improve local circulation.

Here's how it works:

When specific wavelengths of red and near-infrared light (typically 660nm and 850nm) penetrate your skin, they reach deep into your tissues—including muscles, tendons, ligaments, and even bone.

At the cellular level, these light wavelengths are absorbed by your mitochondria, triggering a cascade of beneficial biological responses:

Increased ATP Production: Your cells produce more energy (ATP), which they use to repair damage, clear waste products, and function optimally. More cellular energy means faster tissue repair and regeneration.

Reduced Inflammation: Red light therapy modulates inflammatory markers, helping your body maintain the right amount of inflammation for healing without the excessive inflammation that delays recovery and causes pain.

Enhanced Blood Flow: Light therapy stimulates the formation of new capillaries and improves circulation, delivering more oxygen and nutrients to your healing tissues while removing metabolic waste more efficiently.

Collagen Synthesis: Red light stimulates fibroblasts to produce more collagen, the structural protein your body uses to rebuild damaged tissue and minimize scar formation.

Pain Reduction: By reducing inflammation and stimulating endorphin release, red light and infrared therapy helps ease pain.

The result? Your body heals the way it's supposed to—efficiently and thoroughly.

Laser therapy for knee osteoarthritis – meta-analysis of 22 placebo-controlled trials (BMJ Open, 2019).

Across 1,063 patients, light therapy at recommended doses reduced knee pain more than placebo, both at the end of treatment and 2–12 weeks afterward.

Laser therapy plus exercise for knee osteoarthritis (Lasers in Medical Science, 2014).

In 53 patients over 6 weeks, adding laser therapy to exercise lowered pain and improved knee function more than exercise with a placebo laser.

Low-level laser therapy for knee osteoarthritis (2009).

In a placebo-controlled study, 4 weeks of twice-weekly infrared laser therapy reduced knee pain and improved local circulation, changes not seen with placebo.

Light therapy for knee pain in older adults (J Am Geriatr Soc, 1992).

A pioneering trial in elderly patients with knee osteoarthritis found less pain and better mobility after 10 days of treatment.

Over 30 years of studies support light therapy for knee arthritis pain.

Here's What RedRelief Does For You

Living with knee osteoarthritis?

Stiff first steps out of bed, aching stairs and a knee that throbs after a day on your feet are all too common with arthritis, but they don't have to set your pace.

RedRelief™ is built for everyday life with arthritic knees: 20 minutes before you get out of bed to loosen the joint, and 20 minutes at night to calm the ache and stiffness.

You can also use RedRelief™ anytime of the day. You don't need to stick to a tight schedule.

The RedRelief™ Knee Brace combines deep-reaching 850 nm near-infrared and 660 nm red light with soothing heat and gentle massage, so you can ease your knee at home without pills. In just 20 minutes, twice a day, it helps to:

Ease the deep, constant ache of knee arthritis so everyday movement feels easier.
Loosen morning stiffness so first steps, stairs and getting up from a chair are less of a battle.
Boost circulation to the tissues around the knee.
Relax tight, guarding muscles with 5 levels of gentle massage.
Keep you moving so walks and exercise are easier to stick with.

Light therapy is used by physical therapists and athletes. RedRelief™ lets you use it at home, on your own schedule. It's cordless, USB-C rechargeable, and sits right on your knee.

Clinical Citations

Over 30 years of research supports using red and infrared light therapy to treat knee pain and restore joint mobility.

One clinical study of 53 patients with knee osteoarthritis found that combining red light therapy with a rehab exercise program led to greater pain relief and functional improvement than exercise alone.

After 6 weeks, patients who received laser therapy plus exercise reported lower pain scores and better knee function, highlighting that adding red light therapy enhances standard treatment – helping to relieve knee pain and improve daily movement.

I have rheumatoid, Lyme or another inflammatory arthritis. Can I use it?

Check with your doctor first, and start with short, low-heat sessions. Some people with inflammatory conditions feel a temporary flare if they start with long sessions.

I'm waiting for a knee replacement. Is it worth it?

Many people use it to stay active while they wait, and keep using it during recovery afterward.

I'm "bone on bone." Can it still help?

Light therapy can't rebuild cartilage, and nothing on the market can. Many people with advanced arthritis use it to take the edge off daily pain and stiffness. It isn't a substitute for talking with your surgeon if your knee needs surgery.
