What if it doesn't work for me?

All Lingo orders are backed by our 30-day money-back guarantee. If you're not completely satisfied, simply contact us — we'll make it right, no questions asked.

Wear it on your own stairs, on your own walk, for a few weeks. That is the only test that counts.

What is it, exactly?

A patellar strap: a small, firm, contoured pad on an adjustable band. It sits just below the kneecap and applies focused pressure on the patellar tendon, which changes where the load goes when you bend, go down stairs or walk downhill. Many people find that more comfortable than wrapping the whole joint.

It is not a sleeve and not a brace. It does not squeeze your knee, it does not slide, it does not trap heat.

How do I put it on?

1. Sit down and find your kneecap with your fingers. 2. Place the pad about one inch below it, on the soft spot at the front of the leg — not on the kneecap. 3. Close the band so it is snug, never tight: you should be able to slip two fingers under it. 4. Stand up, take a few steps and re-adjust.

Loosen it if you feel numbness, tingling or throbbing. Do not sleep in it.

What's in the pack?

Two Lingo Knee Straps per pack — one for each knee, or one to wear and one to wash. One adjustable size; each strap fits the left or the right leg.

Care

Close the hook-and-loop tab, hand wash in cool water with mild soap, and let it air dry. No bleach, no tumble dryer.

It's Not the Whole Knee.
It's Where the Load Goes.

Going down a step, lowering yourself into a chair, walking downhill: every time, the big muscle on the front of your thigh brakes your body weight, and that pull runs through one tendon just under the kneecap. A sleeve squeezes everything around it. This strap presses on that one spot, and that changes where the load goes.

The Brace in the Back of the Closet

Most people who end up here have already paid for something bigger: a $300 brace from a doctor's office that now lives in the back of a closet, a drawer of neoprene sleeves, shots that wore off after a few months. Wrapping your whole knee to press on one tendon is like wearing a winter coat to keep one hand warm.

Why people switch from sleeves, in the order we hear it.

A bulky knee brace next to the small Lingo strap

The slideIt Ends Up Around Your Shin

A tube of stretchy fabric on a leg that gets narrower toward the ankle only goes one way. By the bottom of the stairs you are pulling it back up.

Standing up from an armchair wearing the strap

The back of the kneeIt Bunches and Scratches

Every time you sit, a sleeve folds into the crease behind your knee. Seams rub, fabric pinches, and that is usually the day it goes into the drawer.

Close-up of the contoured pad

The heatIt's a Wetsuit for One Joint

Neoprene is what divers wear to stay warm. Around a knee, in July, under trousers, it is hot and damp within the hour.

Rolling jeans down over the strap

The lookEverybody Can See It

A big black brace announces itself under any pair of pants. A strap two inches tall does not. Roll your jeans down and it is gone.

"Won't It Slide Down Like Everything Else?"

Fair question. It is the first thing everyone asks, so here is the plain answer.

Where it sits

In the notch under the kneecap

Right below the kneecap the leg dips in, then the calf widens again. A narrow strap sits in that notch. A long sleeve has nothing to hold on to.

The pad

Firm and contoured, not flat elastic

The front pad is shaped to follow the leg and firm enough to keep its place. You set the band once with the hook-and-loop tab, to your own leg.

If it moves

It is one of two things

Too loose, or too high. Snug it one notch, or slide it down off the kneecap. The placement guide below takes thirty seconds.

Two Inches of Strap. Not a Wetsuit.

It covers a thin band of skin under the kneecap and leaves the rest of your knee alone.

Where It Goes: One Inch Below

Placement is everything with a strap this small. Get this right and you have given it a real chance.

Get My Pair

1. Find the kneecap

  • Sit down, leg relaxed, knee bent
  • Feel for the round, hard edge of the kneecap with your fingers

2. Go one inch below it

  • Just under the kneecap there is a softer spot: that is the tendon
  • Centre the pad there, on the front of the leg
  • The most common mistake is wearing it ON the kneecap, where it presses on bone and does nothing

3. Snug, never tight

  • Close the band so it does not move, and no more
  • You should be able to slip two fingers under it
  • Numbness, tingling or throbbing means it is too tight: loosen it

4. Stand up and walk

  • Take the stairs once, then re-adjust if you need to
  • Wear it for the things that load the knee: stairs, walks, a long day on your feet
  • Take it off to sleep

Plain Answers. Including the Unflattering Ones.

What a patellar strap does, what the research actually covers, and who should skip it.

What it actually doesPressure on one tendon. That's it.
The strap presses on the patellar tendon just below the kneecap. That slightly changes the angle between the kneecap and the tendon and where the load goes when the knee bends under weight. Many people find stairs, squatting down and walking downhill more comfortable with it on. It is mechanical, it is immediate, and it only works while you wear it.
What the research coversAthletes with tendon trouble, not arthritis.
A laboratory study in Sports Health (2011) X-rayed the knees of 20 adult men with and without an infrapatellar strap and ran the measurements through a computer model of a jump landing: in most participants the strap lowered the predicted strain at the spot where "jumper's knee" occurs. A 2016 randomized trial of 97 athletes with patellar tendinopathy (average age 27) found less pain on a squat test with a strap than with nothing, but not less than with a placebo tape. These studies were on athletes with tendon problems, not on people with arthritis, and none of them tested this particular strap.
Will it weaken my knee?It's a tool to stay active.
A strap this small does not hold your knee up or do the work of your muscles, so it is not a crutch in that sense. It is also not a substitute for the strengthening work a physical therapist would give you. Think of it as the thing that lets you keep walking, playing and taking the stairs while you do the rest.
Who should skip itWe would rather say it up front.
If you have circulation problems, a history of blood clots, or skin that breaks down easily, ask your doctor before wearing any strap around your leg. If your knee is swollen, unstable or gives way, that needs a diagnosis, not an accessory. And if your pain is severe or persistent, talk to your doctor.

5 Reasons Why

Why This One and Not the One in Your Drawer

Reason 1

It Presses on One Spot

Not the whole joint. One firm, contoured pad on the tendon just below the kneecap, which is where the load runs through when you bend.

Reason 2

It Stays Where You Put It

It sits in the notch under the kneecap and you set the band to your own leg. No tugging it back up at the bottom of every staircase.

Reason 3

No Heat, Nothing Behind the Knee

Two inches of strap instead of a neoprene tube. Nothing folds into the crease when you sit, nothing gets damp by lunchtime.

Reason 4

Nobody Knows It's There

Thin enough to vanish under jeans, slacks or leggings. You can wear it to dinner, to work or to church without announcing anything.

Reason 5

Two in Every Pack

Buy one, get one free: one for each knee, or one on and one in the wash. One adjustable size, and each strap fits either leg.

Straight Talk: What It Won't Do

Knee products oversell. A strap should not.

Not a treatment

It does not treat arthritis

It does not treat, cure or reverse arthritis, it does not regrow cartilage, and it does not replace a doctor, physical therapy or surgery. Nothing you strap on does.

Not a shortcut

It does not replace strengthening

Strong thighs and hips are what protect a knee over the years. The strap is there to make staying active more comfortable while you do that work.

Not for everyone

Some knees need a doctor first

Swelling, giving way, locking, or pain that is severe or persistent deserves a diagnosis. If that is you, talk to your doctor.

Questions People Ask Before They Buy

How can something this small do anything?
Because it is not trying to hold your knee together. It presses on one tendon, just below the kneecap, and that changes where the load goes when the knee bends under your weight. A bigger brace is not a stronger one; it is just bigger. Whether it helps your knee is something only your own stairs can tell you, which is what the 30 days are for.
Does it help with arthritis?
We will be straight with you: it does not treat arthritis, and the research on this kind of strap was done on athletes with tendon problems. The one small pilot study we found in people with knee osteoarthritis (10 patients) saw them put weight on the leg more evenly in a squat, but their pain was about the same with and without the strap. Some people with worn knees tell brands like ours that stairs feel better with a strap on; others feel nothing. Try it for 30 days and keep your doctor in the loop.
Will it slide down?
It sits in the notch just under the kneecap, where the leg dips in before the calf widens, and you set the band to your own leg. If it moves, it is either too loose or sitting too high on the kneecap: slide it down an inch and snug it one notch.
How tight should it be? Can it cut off circulation?
Snug, not tight, and never like a tourniquet. It only has to stay in place; you should be able to slip two fingers under the band. Loosen it right away if you feel numbness, tingling or throbbing, and do not sleep in it. If you have circulation problems or a history of blood clots, ask your doctor before wearing it.
Will one size fit my leg?
The band is adjustable with a hook-and-loop closure and each strap fits the left or the right leg. If it does not fit you, the 30-day guarantee covers it: contact us and we will refund you.
Can I wear it all day, under my clothes?
Yes. It is about two inches tall and sits flat, so it disappears under jeans, slacks or leggings. Wear it for the parts of the day that load your knee — stairs, walks, errands, a long shift on your feet — and take it off at night.
Will wearing it make my knee weaker?
A strap this small does not do the work of your muscles. It is a tool to stay active, not a substitute for the strengthening exercises a physical therapist would give you. The best plan is both.
Why are there two in the pack?
Because most people want one for each knee, and the rest like having one to wear while the other dries. Every pack is Buy 1, Get 1 Free. Each strap fits either leg.
What if it doesn't work for me?
Then you should not pay for it. Wear it for a few weeks; if it is not for you, contact us inside 30 days and we will refund you, no questions asked.

Individual results vary. The Lingo Knee Strap is a support accessory. It is not intended to diagnose, treat, cure or prevent any disease, and it does not replace medical advice, physical therapy or surgery. If your pain is severe or persistent, talk to your doctor.

Wear it snug, never tight. Remove it if you feel numbness, tingling, swelling or skin irritation. Do not sleep in it. Ask your doctor first if you have circulation problems or a history of blood clots.
