The Strap That Sits On One Inch, Not Around The Whole Knee

★★★★★ 4.8 out of 5 · 1,240 wearers

A single adjustable band that presses on the patellar tendon an inch below the kneecap — the spot the load actually lands on when you are going down. It goes on in about five seconds, it stays where you put it, and nobody can see it under a pair of jeans.

Why The Drawer Full Of Braces Never Did Anything

It is not that they were cheap ones. It is that they were aimed at the wrong part of the knee.

Knee sleeves wrap everything and target nothing. That is why it comes straight back the second you take one off.

What a sleeve does

It squeezes the whole joint evenly, from every direction at once. It feels supportive because it is tight — and tight is not the same as unloaded. The tendon under your kneecap is carrying exactly what it was carrying before you put it on.

What Onepoint does

It presses on one inch of the patellar tendon, an inch below the kneecap. That single contact point changes the angle the tendon pulls at, and moves load off the sore spot and onto the band.

Going down a step is the worst thing you ask that tendon to do all day. The muscle at the front of your thigh is not lifting you — it is paying you out, like a rope — and all of that braking runs through one cord below the kneecap, landing on the same patch every time. That is the inch this sits on.

It Goes On In About Five Seconds

There is nothing to charge, nothing to install and nothing to remember.

The Mantle Onepoint strap fastened an inch below the kneecap
  1. Sit down and find the cord.Run a thumb from the bottom of your kneecap toward your shin. The firm band you feel under the bone is the patellar tendon.
  2. Fasten it across that band.About an inch below the kneecap. Firm, not tight — you should be able to slide a finger underneath it.
  3. Stand up and go down a step.That is the whole test, and it is the movement it was built for. Wear it on the knee that bothers you, or one on each.

I have one on each knee for the garden. Three hours out there the day they came. My daughter thought I had hired somebody.

My son stopped asking me to hold the ladder. Nine weeks after I started wearing this he asked me to help him do the gutters, and I still have not told him what changed.

I wear mine under work pants for a twelve-hour shift and forget it is there. Nobody at work has ever noticed it.

Questions people ask before they order

If yours is not here, email us and a person will answer it.

Where exactly does it sit?
One inch below the kneecap, across the patellar tendon — the cord you can feel between the kneecap and the shin bone. Sit down, find the soft band just under the bone, and that is the spot. It should be firm, not tight.
Is this the same as a knee sleeve?
No. A sleeve is a tube of fabric that compresses the whole joint from every direction. This is a single band that presses on one point and nothing else. If you have a drawer of sleeves that did nothing, that is the difference.
Will it fit me?
One size. The strap adjusts across a wide range and fits most adult legs. It sits flat enough to wear under jeans, work pants and leggings without showing.
Which knee do I put it on?
The one that bothers you. Most people order two so they have one for each leg, which is why the smallest pack is two straps.
How long do I wear it for?
Put it on in the morning and wear it through the day. There is nothing to charge, nothing to replace and nothing to remember.
Can I wear it for work?
Yes. It is designed to stay put through a twelve-hour shift, and under work pants nobody will know it is there.
What if it is not right for me?
Send it back inside sixty days for a full refund. That is the whole policy.
Is this a medical device?
No. It is a support garment. It is not a substitute for medical care, and if your knee pain is new, severe, follows an injury or is getting worse, see a doctor.
