In a randomized trial of 97 athletes with jumper's knee, a patellar strap reduced knee discomfort during a single-leg squat compared with no strap. ¹
Questions people ask first
01 I've tried sleeves and straps before. Why would this be different?
That drawer full of sleeves and braces doesn't mean your knee is beyond help. It means they were aimed at the wrong spot. A sleeve squeezes your whole knee and rolls down your calf by lunchtime, and a foam strap slides off the spot or gets cranked too tight, so the tendon just below your kneecap, the one that takes the hit on every stair, never gets any help.
KeepUp's soft silicone pad sits right on that spot, takes the load off it and grips your skin so it stays there all day. And nothing in that drawer came with a plan to make your legs stronger, which is what the 6-week guide does. Try both for 60 days, and if they don't help, you get every cent back.
02 Can it help if I've hurt my knee?
Yes. Lots of people wear this strap while they're getting back from a knee setback, because the pad takes load off the tendon on stairs and walks, so you can keep moving instead of sitting it out. If it's a fresh injury, get it checked first, then put the strap on and start the guide at Level 1.
03 Can I use the guide for rehab?
Yes. It's built on the same slow, progressive strength work physiotherapists use to get knees back in shape. It starts gentle, adds a little each week, and has a traffic-light rule so you always know how hard to push. Plenty of people use it alongside their physiotherapy plan, or to keep going once their sessions end.
04 It looks so small. Does it really do anything?
Yes, and it's small on purpose, because it only has one job. It presses on the tendon just below your kneecap and takes load off it, right where stairs, hills and getting up from a chair put the most strain, so you feel steadier from the first step. In a randomized trial of 97 athletes with jumper's knee, a patellar strap reduced knee discomfort during a single-leg squat compared with no strap. ¹
Then the guide builds the leg strength that keeps your knees doing their job long after the first week, and that pairing is what keeps you on your walks, down in the garden and on the floor with the grandkids.
05 Can't I just rest it and wait for it to settle down?
You can, and that's what nearly everyone tries first. The trouble is that rest calms a sore knee for a while but doesn't make it any stronger, so the ache is waiting for you the next time you take the stairs, kneel in the garden or walk to the end of the block. Meanwhile you're skipping the walks, your legs are getting weaker, and every week of that makes the next flight of stairs harder. Nobody wants to wait it out until the conversation turns to scans and surgery.
Modern physiotherapists do it the other way around. They take the load off the knee and build the legs back up, slowly, a little more each week. The strap does the first part the moment it's on and the guide does the second, and you can do session 1 tonight.
06 What's in the 6-week guide?
The guide is the part that makes this last. The strap takes the load off today, and the guide builds legs strong enough that your knees stop dreading the stairs. It's built on the methods modern physiotherapists use for knees, slow strength work that starts easy and asks a little more of your legs each week, and it's the approach that has helped thousands of people go from sitting it out to keeping up again.
You do three 15-minute sessions a week at home with a wall, a chair and one stair, so there's no gym and no weights. Weeks 1 and 2 start easy, and by the end of them the stairs start to feel like less of a project. Weeks 3 and 4 add the slow step-down you use coming down the stairs, so you feel steadier on the way down. Weeks 5 and 6 build up to one leg at a time, the strength that gets you up off the floor without reaching for the couch and back out on the long walks. It's in your inbox right after you order, so you can start tonight, before the straps even arrive.
07 Will it slide down?
No, it stays put once it's on the right spot, and that's the complaint that sinks most straps. The silicone pad grips your skin and a buckle on each end pulls it on evenly, so it stays put through a long walk, an afternoon kneeling in the garden and a full game. Put the pad on the soft spot just under your kneecap, pull both ends snug and bend your knee a few times, and you're set for the day.
08 Will it be too tight, or pinch?
No, because you set the fit yourself. You pull the buckles to snug and stop there, since tighter doesn't work any better. It's one flat strip, so the rest of your knee stays open to the air instead of turning into a sauna the way it does in a sleeve, and you can wear it all day under jeans or work pants and forget it's there.
09 Will it fit my leg?
Yes. It's one size and the strap adjusts to fit most legs, slim or strong. If you have bigger legs and want to be sure, email us the measurement around your leg just under the kneecap before you order and we'll check it for you. And if it still isn't right, the 60-day promise has you covered.
10 Should I get one pair or two?
Two is the smart choice, and here's why. One pair covers both your knees, because it's rarely just one knee. Two pairs gets you four straps for $54.99, which works out to $27.50 a pair, so you save $12.49 a pair. That second set can go to your husband or wife, your walking buddy or whoever you've watched hesitate at the top of the stairs, or it stays in the car so you're never without a pair when the other one's in the wash.
You get the guide with either pack, and it's a lot easier to stick with when there are two of you doing it after breakfast.
11 How long does shipping take?
Fast, free shipping to the US. Most orders arrive in 7–11 days, with tracking from day one. The guide doesn't wait for the mail, though. It's emailed right after you order, so you can do your first session before the straps arrive.
12 Is the guide based on real physiotherapy methods?
Yes. It's built on the methods modern physiotherapists use to get knees strong again after an injury: slow strength work that adds a little each week, so your knee takes more load without flaring up. That approach has helped thousands of people get back to the stairs, the walks and the game, and the guide puts it in 15 minutes a day at home, while the strap takes the load off from the first step.
13 What if it doesn't work for me?
Then you get your money back. Email us any time within 60 days of delivery and we'll refund you in full, with nothing to fill in and nothing to send back, and you keep the straps. So the worst case is you tried it for free. The best case is the stairs, the walks and the Saturday round stop being a problem.

Includes reviews of this strap from buyers on other stores.
Why the sleeve in your drawer didn't work, and why this does
A sleeve squeezes your whole knee and rolls down by lunchtime, so the spot that actually aches gets nothing. KeepUp goes straight for that spot. A soft silicone pad takes the load off the tendon just below your kneecap, the one that works hardest on stairs, hills and every time you stand up, and it grips your skin so it stays there all day. In a randomized trial of 97 athletes with jumper's knee, a patellar strap reduced knee discomfort during a single-leg squat compared with no strap. ¹
Then the 6-week guide builds the leg strength that keeps you on the stairs, out on your walks and down in the garden long after the first week.

The strap: steadier from the first step
It takes the load off the tendon the moment it's on, so you feel steadier on the very first stair, and it stays put under your slacks, through a long walk and an afternoon kneeling in the garden.
The guide: knees that keep up for good
It's built on the methods modern physiotherapists use for knees, the approach that has helped thousands go from sitting it out to keeping up again. It takes 15 minutes, 3 times a week, with a wall, a chair and one stair, and by week 6 you're working one leg at a time.

For anyone who's tired of asking everyone to slow down
Stairs, chairs and the floor
For the stairs you've started taking one at a time, the armchair you push out of with both hands, and getting back up off the floor without making a whole production of it.
Walkers and gardeners
For the walk around the lake you've started cutting short, and the tomato beds you gave up because kneeling down and getting back up got too hard.
Grandparents and couples
For racing the grandkids to the swings instead of waving from the bench, and for the one you've watched hesitate at the top of the stairs. Two pairs covers you both.
Pickleball, tennis and golf
For the player who's started skipping the second game, so you're back for Tuesday open play and all 18 holes on Saturday.
And if you already have a drawer full of sleeves, braces and tape, it's because none of them sat on the tendon just under your kneecap, which is the one spot this strap goes straight for.

Six weeks from gripping the rail to keeping up with everyone again
The stairs get easier
Wall sits, standing up from a chair and low step-ups wake up the muscles that take the load off your knee, and the stairs start to feel like less of a project.
Steadier on the way down
Slow step-downs from a stair, the exact move your knee dreads, plus split squats with a pause, so you lean on the handrail less and your legs more.
Keeping up again
Step-ups, full split squats and one leg at a time, the strength that gets you up off the floor, through the long walk home and back to the second game.
- Tonight. The guide lands in your inbox right after you order, so session 1 happens before the straps even arrive.
- Every session. Tick a box in the tracker, and once a week rate how the stairs felt from 1 to 10, so you can see the change for yourself.
- Any time in the first 60 days. If it isn't helping, one email gets you a full refund, and you keep the straps.
It's rarely just one knee, so every order comes with two straps
Every month you spend holding the rail, cutting the walk short and watching the grandkids from a chair costs you more than $39.99, and your legs don't get any stronger sitting it out. One pair covers both knees. Two pairs is $54.99, just $27.50 a pair, so your partner gets a set too, or you keep a spare in the car.
