“Which knee is it on?”
My daughter asked me that at dinner. Sitting right next to me. I wear it under my slacks every day now and nobody has a clue.

When do your knees start having opinions?
None of this means you are slowing down. Your knees just want a little backup.
- 7:00The first stairs of the day.
- 10:30Kneeling to pull weeds. Then getting back up.
- 2:00The car door. The low seat.
- 6:00The dog wants the long loop.
- 8:30The stairs again. Somehow longer.
The underline
Kneecap
SoftWing pad
Most supports go around your knee. Bendio goes under it.
Just under your kneecap is a soft spot we call the underline. The SoftWing pad sits right on it and leaves the rest of your knee free.

How can a strap this small do anything? Scientists wondered too.

It rests on the tendon.
The pad sits on the cord just under your kneecap.

Your thigh pulls less.
So the spot under your kneecap takes less strain.
What the research says
Randomized trial · 97 athletes
−14points
less pain on a tough squat test, compared with wearing nothing
How they tested it
In a randomized trial, 97 athletes with jumper's knee tried a patellar strap, sports tape, placebo tape and nothing at all. With the strap, pain on a single-leg squat dropped by 14 points on a 100-point scale compared with nothing. It did not beat the placebo tape.

Lab study · 60 people
37 → 28
pain score when landing a hop, out of 100
How they tested it
30 people with jumper's knee and 30 without it hopped and landed on one leg, with and without a strap. With the strap, pain scores in the jumper's knee group fell from about 37 to 28 out of 100, and both groups landed with less peak force.

X-rays + computer model
16 of 20
knees showed less tendon strain in the computer model
How they tested it
Researchers X-rayed 20 men aged 24 to 62 with and without two different straps. A computer model then predicted less strain at the jumper's knee spot in 16 of the 20 men with one strap and 15 of 20 with the other.

On in ten seconds. Really.
I timed it because I did not believe the page. Pad under the kneecap, wrap, done. My old brace took longer than my coffee.

Took a day to get the spot right.
The first day I had it too high. Once I put it two fingers below the kneecap like the card says, the stairs at church were a different story. Four stars only because I wish I had read the card first.

Getting back up was the part I dreaded. I wear it for my morning in the beds and it washes clean with soap in the sink.

Good, wish it came in black.
Does what it says and stays put on my walks with the dog. The cream color shows under shorts, so I wear it under pants.

Flat enough that you cannot see it under skinny jeans. I was sure it would show. It does not.

Simple. No straps everywhere.
My hands are not what they were. One band, one buckle. My wife does not have to help me anymore, and I walked all nine holes.

Fine, but not magic.

contact@bendio.coA real person replies within a day.Will it actually help my knee?
If stairs, chairs or kneeling bother your knee, the tendon just under your kneecap is doing a lot of that work. That is where Bendio sits. Try it on your own stairs. If it does nothing for you in 60 days, you get every cent back.
Is this the same as the cheap straps online?
Most cheap straps are a foam tube on a scratchy Velcro band. Bendio has a soft, curved silicone pad shaped to cup the bottom of your kneecap, and a smooth band that does not dig into the back of your knee. And you get a real company behind it: a person answers your email and the refund is a real refund.
Will you really refund me?
Yes. Email us within 60 days and we refund you in full. No haggling, no partial refunds, no 'try it a bit longer'. Our guarantee is honored exactly as written.
Will it fit my leg?
One size fits all. The band adjusts in seconds, from slim legs to fuller ones. If it does not fit you, we refund you.
Will it slide down or dig in?
The silicone pad grips your skin, so it stays where you put it. The band is smooth and soft, so nothing rubs the back of your knee.
How tight should it be?
Snug, never tight. You should be able to slide a finger under the band. If your leg tingles or feels numb, loosen it.
Can I wear it all day? Under jeans?
Yes. It is flat and light, so it disappears under jeans, slacks and leggings. Most people put it on for the stairs, the walk or the garden, then take it off.
One, two or four?
One knee: get 1. Both knees, or someone walks with you: get 2. Spares for the car and the bag, or two of you: get 4, the best value. Shipping is free from 2 straps.
Is this a real company, or one of those ads?
Fair question. We are a small team, a real person answers every email within a day, and the guarantee is honored exactly as written.
Your stairs are waiting.
So are the grandkids, the garden and that long loop with the dog.
