See How It Fits

Is It Right For Me?

It’s made for people who feel it just below the kneecap: on the stairs, on long walks, at the end of a long day on their feet. If you have an injury or ongoing knee trouble, ask your doctor or physical therapist first.

Will It Fit My Leg?

One size, adjustable. The hook-and-loop strap closes where it feels snug. Measure around your leg just below the kneecap: it fits about 10 to 18 inches.

How Do I Put It On?

Find the bottom edge of your kneecap. Set the pad two fingers below it, on the soft spot. Close the strap firm, not tight. About 10 seconds.

When Every Staircase Becomes A Plan

It starts small: a tug just below the kneecap on the way down the stairs. Then it shows up on long walks, when you stand up, at the end of a long day.

  • Holding the handrail on every staircase
  • Taking the short way round on walks
  • Pulling a bulky sleeve back up every few minutes

A sleeve squeezes the whole knee. The spot that takes the load is just below the kneecap.

Why Stairs Feel Harder

Stairs Load The Front Of Your Knee

Stairs put about 3x your body weight through the front of your knee.

Why KneeLift

Small Strap, Right Spot

Pressure In One Spot

The curved pad presses on the tendon below your kneecap, not on your whole knee.

Slim, Not Bulky

A thin band instead of a hot, heavy sleeve. It fits under most pants.

Stays Where You Put It

A narrow band holds its place while you walk. The silicone pad grips your skin so it does not slide.

On In 10 Seconds

One strap, one pull. No straps to thread, no sizes to guess.
The Idea Behind It

What Studies On Knee Straps Found

Patellar tendon straps have been used in sports medicine for decades. KneeLift makes the idea slim enough to wear every day.

1

In a lab study, a strap below the kneecap lowered predicted tendon strain in most of the 20 knees tested.

Lavagnino et al. 2011, Sports Health

2

In a 2016 trial, a patellar strap lowered pain during activity in the short term.

Finally, stairs again

I bought one strap for my left knee and wore it the first time going down to my laundry room. The difference was immediate. I ordered two more the same week.

T Tom B. Verified Buyer

Wore it on a 3-mile walk

My right knee has been bothering me for about a year, mostly on longer walks. Strapped this on below the kneecap and did my usual loop. No issues. It's thin enough I forgot I was wearing it.

L Linda R. Verified Buyer

Not bulky like the sleeve I had

I tried one of those big neoprene sleeves and it kept sliding down and bunching behind my knee. This stays put and I can wear it under my pants without anyone knowing.

J James K. Verified Buyer

Does what it says

Solid strap. Took me a minute to figure out the right tightness but once I got it dialed in, going up and down stairs is noticeably easier. Taking one star off because the instructions could be clearer.

C Carol M. Verified Buyer

Got me back in the garden

Kneeling and getting back up was the worst part of my day. With the strap on I can spend a couple hours out there without dreading standing up. My neighbor asked where I got it.

R Robert P. Verified Buyer

Bought the 3-pack, no regrets

One for each knee plus a spare in my gym bag. I play pickleball three times a week and these let me lunge without thinking about it.

S Susan H. Verified Buyer

Simple and it works

No complicated sizing, no velcro that wears out after a week. Just put it on and go. I wear mine every morning on my walk with the dog.

G Gary W. Verified Buyer

Good for long days on my feet

I'm on my feet all day at work. Started wearing this about two weeks ago and the end of my shift doesn't feel as rough. Wish shipping was a little faster but overall happy.

D Diane L. Verified Buyer

Wish I found this sooner

I spent way too much on bulky braces that ended up in a drawer. This little strap does more than any of them. My husband tried mine and ordered his own the same day.

M Mark T. Verified Buyer

Hiking again

Bad right knee kept me off the trails for months. A friend suggested a patellar strap and I found KneeLift. Did a 4-mile hike last weekend, downhill included.

P Patricia D. Verified Buyer

Skeptical but it actually works

I almost didn't order because it looked too simple. A tiny strap? Really? But I figured the 90-day guarantee meant I had nothing to lose. Wore it grocery shopping and the difference going in and out of the car was obvious. Ordered a second one the next morning.

R Richard N. Verified Buyer

Kept up with my grandkids

Took the grandkids to the zoo last Saturday. Normally I have to sit on every bench and let them run ahead. Wore both straps and stayed on my feet the entire time. My daughter kept asking if I was okay and I just smiled.

B Barbara J. Verified Buyer

Good quality, runs a bit stiff at first

The strap felt a little stiff out of the package. After wearing it a couple of days it softened up and now it is very comfortable. I wear it under my slacks to work and nobody can tell. Four stars because I wish that was mentioned somewhere.

L Larry F. Verified Buyer

Three months in, still holding up

I have had mine for about three months now. I wear them four or five days a week and they still look and feel like new. The velcro has not started peeling and the pad has not flattened out. Best forty dollars I have spent on my knees.

J Janet C. Verified Buyer

My physical therapist noticed

I wore it to my PT appointment and she asked what I had on under my pants. Showed her the strap and she said the placement was exactly right. That was all the confirmation I needed.

D Dennis A. Verified Buyer

Better than the $80 brace I had

I spent eighty dollars on a hinged brace from the pharmacy. It was so bulky I stopped wearing it after a week. This strap cost less and I actually use it every single day.

K Karen W. Verified Buyer

Works great, wish I ordered two

Both knees bother me but I only ordered one strap to try it. It made such a difference I immediately ordered a second. Should have just gotten the three pack from the start.

F Frank M. Verified Buyer

Back to coaching Little League

I had to give up coaching because I could not crouch behind the plate anymore. Wore these to the first practice of the season and made it through the whole thing. The team was happy to have me back.

FAQ

Questions, Answered

Where Exactly Does It Go?

Just below your kneecap, on the soft spot where the tendon runs. The curved pad sits across it, the strap goes around the back of your leg.

I've Tried Sleeves And Braces. Why Is This Different?

A sleeve squeezes your whole knee and a hinged brace holds the whole joint. KneeLift presses on one spot: the tendon just below the kneecap. It is a different idea, small on purpose.

It Looks Small. Does It Really Do Anything?

It only needs to cover one spot. In a 2016 trial, a patellar strap lowered pain during activity in the short term (a study on patellar straps in general, not on this product). Try it on your own stairs: you have 90 days.

Will It Fit My Leg?

One size, adjustable. Measure around your leg just below the kneecap: it fits about 10 to 18 inches.

Will It Slip When I Walk?

The silicone pad holds against your skin, so it stays where you put it when it is closed snug.

How Tight Should It Be?

Firm, not tight. You should feel the pad pressing, and your leg below it should never tingle or go numb.

Can I Wear It Under Pants?

Yes. It is a thin band, so it fits under most pants and leggings.

Can I Wear It All Day?

It is light and slim enough for a long day. Take it off when you sit for a long time, and loosen it if your leg below it ever tingles.

Should I Get One Or Two?

Most people get two, one for each knee. If only one knee bothers you, one strap is enough.

Is It A Medical Device?

It is a comfort and support strap. If you have an injury or ongoing knee trouble, talk to your doctor or physical therapist first.

What If It Doesn't Work For Me?

You're covered by our 90-Day Money-Back Guarantee: email us within 90 days for a full refund, and keep the straps.

When Will It Arrive?

Delivery takes 3-7 business days in the US.
