KneeStrap Adjustable Patellar Tendon Strap
Sharp pain under the kneecap on the stairs? Take the stairs back.
- Stairs, squats, the way down? the load hits one small spot right under your kneecap
- A silicone pad presses right there and helps take pressure off the patellar tendon with every step
- Thin, breathable, one size, on in 10 seconds and invisible under your pants
How does KneeStrap work?
With every step, and even more on the way down the stairs, your thigh muscles brake your body weight and pull on the patellar tendon, the short band right under your kneecap. All that pull lands on one small spot. KneeStrap's silicone pad presses on that exact spot, so part of the pull is taken up at the pad. It helps take pressure off the tendon and helps you move more comfortably while you wear it.
How do I put it on?
Sit with your knee slightly bent. Place the strap just below your kneecap, with the pad centered on the soft tendon. Close the strap so it feels snug, not tight. It takes about 10 seconds.
How is it different from a knee sleeve?
A sleeve squeezes your whole knee like a hug, and it often rolls down. KneeStrap is a thin band that aims at one spot, the patellar tendon, and stays put thanks to its non-slip silicone pad.
When should I wear it?
During the moments that bother your knee: stairs, long walks, hikes (especially the way down), runs, workouts, or a long day on your feet or on your knees. You can wear it as long as it feels comfortable, and take it off when you rest.
Will it fix my knee?
No strap can honestly promise that, and we won't. KneeStrap supports your knee while you move. Studies on infrapatellar straps show relief mostly while you wear them. That's why it comes with a 60-day money-back guarantee.
Everything your knee needs on the stairs. Nothing it doesn't.

It's not your whole knee. It's one small spot under your kneecap.
Knee pain on the stairs often comes from the patellar tendon, the short band that links your thigh muscles to your shin.
Think of it like a rope over a pulley. Every time you step down, your thigh muscles brake so you don't drop, and they pull on that rope. On the stairs or a steep trail, that pull gets stronger, step after step, and it all lands on one small spot right under your kneecap. That's why the way up feels fine and the way down burns. A knee sleeve squeezes the whole knee but never aims at the rope. KneeStrap does.
1. Place it under the kneecap
The thin band sits just below your kneecap, with the silicone pad centered on the tendon.
2. The pad takes part of the pull
Every time your foot lands, the pad presses on the tendon, so part of the pull is taken up at the pad instead of running through that one sore spot. It helps take pressure off the tendon while you move.
KneeStrap works on the tendon under the kneecap, not on the cartilage or the joint itself.
Simple design. Every part has a job.
No batteries, no gels, no bulky hinges. Just a thin strap that stays where it should.
Non-slip silicone pad
A soft, contoured pad that presses on the patellar tendon and grips the skin so the strap doesn't slide.
In a 2019 study, an infrapatellar strap reduced local knee pain in young athletes with patellar tendon pain, without lowering their jump height.
Breathable knit band
A thin, flexible knit that lets your skin breathe and disappears under jeans, scrubs or work pants.
Hook-and-loop closure
Lets you set the pressure you like in seconds, and fits most knees with one size.
Low-profile shape
No hinges, no straps behind the knee: you bend, squat, kneel and climb freely.
Study results refer to research on infrapatellar straps in general, not to KneeStrap. Relief in studies was mostly while the strap was worn.
Most knee supports squeeze. KneeStrap aims.
If your sleeve rolls down halfway through the walk and your brace feels like a cast, here's the difference.

KneeStrap works while you wear it. Here's how most people start.
Find your spot
Put it on, center the pad under the kneecap and take the stairs. Adjust the snugness until it feels right.
Wear it where it hurts
Stairs, walks, the gym, a long shift: wear it during the moments that bother your knee and see how they feel.

Made for people who refuse to stop moving
You jump, lift or play
Basketball, volleyball, squats: the pain under your kneecap shows up on every jump and you're scared of making it worse.
Stairs and chairs bother you

Walks, gardening, chasing the grandkids: you're tired of sleeves that slide down and want something simple.
You're on your feet or knees all day
Trades, nursing, restaurants: you need something thin that fits under your work pants.
