Patellar tendon band
It presses on one small area, just below the kneecap
This is not a sleeve and it does not wrap the joint. It is a single moulded band, wider than it is tall, with a scooped top edge shaped to tuck under the bottom of the kneecap. A flat webbing strap threads through a plastic keeper at each end, passes behind the knee and fastens back on itself, so you decide how firmly the band is held against the front of your leg.
Everything it does, it does through that one contact patch. The band sits across the patellar tendon — the cord you can feel between the bottom of your kneecap and the bump on your shin — and holds steady pressure there while you move. The kneecap itself stays uncovered, and so does the back of the knee.

Placement is the whole product
A band like this in the wrong position is a band doing nothing. It is worth two minutes to get it right the first time, because the difference between a useful spot and a useless one is about a finger's width.
Find the bone
Sit down with the leg out straight and relaxed. Feel for the bottom edge of your kneecap.
Drop below it
Move down about a finger's width. You are now on the tendon — a firm cord running to the bump on your shin.
Seat the scoop
The band's curved top edge tucks under the kneecap, not over it. The bone should stay bare.
Pull, then check
Draw the strap round the back and press it down. Firm enough to stay put through a bend — no firmer.
Two tests before you go anywhere. Bend the knee fully and stand back up: the band should stay where you put it. Then check your foot — if anything tingles, goes cold or goes numb, it is too tight. Loosen it.
Straight answer
What the research actually found
Straps like this have been tested properly, which is more than most things in this category can say. The results are real but they are narrow, and the honest version is more useful to you than the usual promise.
The largest randomised trial put 97 athletes with patellar tendon pain through loaded tests wearing a strap, sports tape, a placebo, or nothing. Wearing the strap cut pain on a single-leg decline squat compared with wearing nothing. It did not beat the placebo.
A separate study of young jumping athletes found the same shape of result: less pain during jump tests with a strap on, and jump height completely unchanged.
Athletes tested
The size of the main randomised trial, published in the Scandinavian Journal of Medicine & Science in Sports in 2016.
Lower pain score
How far pain fell on a 100 mm scale during a single-leg decline squat with the strap on, against wearing nothing.
As the placebo
In that same trial the strap did not beat a dummy. Part of the effect is the pressure; part of it is wearing something at all.
For pain felt behind the kneecap rather than below it, the picture is weaker again. A 2015 Cochrane review of five trials, and a 2012 review in the British Journal of Sports Medicine, both concluded that knee braces, sleeves and straps added nothing measurable to an exercise programme.
The ceiling
What this band does not do
We would rather you buy it for what it is than return it for what it isn't.
- It does not treat anything. Tendinopathy, arthritis, a meniscus tear, ligament damage — none of those are affected by a band worn on the outside of the leg. It changes how a knee feels while you use it. It does not change what is happening inside it.
- It does not realign your kneecap. Nothing worn below the kneecap moves the kneecap.
- It does not stabilise the joint. There are no hinges, no side stays and no rigid frame. A knee that buckles, catches or gives way needs a clinician, not a band.
- It does not make you faster or stronger. Where jumping was measured directly, performance was unchanged.
- It is not a substitute for loading the tendon properly. The treatments with the strongest evidence behind them are progressive strength work and managing how much you do. A band can sit alongside that. It cannot replace it.
Fit
One size, and one measurement worth taking
There are no graded sizes to choose between. The moulded band is a fixed shape; all of the adjustment lives in the webbing strap, which threads through the keeper on each side and fastens back on itself anywhere along its length.
The supplier states it fits a below-knee circumference of roughly 11–18 in (28–45 cm). Measure it before you buy: run a tape around your leg about 1–2 in (3–5 cm) below the bottom of your kneecap, standing, with the leg straight. If you land near either end of that range, it is worth knowing now rather than after it arrives.
It is symmetrical. The same band goes on the left knee or the right, worn either way round. Choose one band, or a two-pack if you want one for each knee.
Materials and care
What it is made of
Three parts. The band itself is a flexible moulded shell with a soft matte finish — firm enough to hold its curve, soft enough to flex when the knee bends; the supplier specifies silicone. Its inner face is raised into a horseshoe-shaped cushion ringed by concentric ridges, and that is the part that actually meets your leg. The end keepers are rigid plastic, and the strap is a soft flat webbing that fastens with hook-and-loop. The whole thing weighs about 1.8 oz (50 g).
The front face carries a scattered field of small moulded dots. They are a grip and surface texture in the moulding, not ventilation holes — the band is not ventilated, and we would rather say so than have you buy it for airflow it does not have.
Hand wash it in cool water with a little mild soap, fastening the hook-and-loop closed first so it does not pick up lint, and dry it flat and away from direct heat. No machine wash, no tumble dryer, no bleach, and do not leave it in a hot car — heat is what warps a moulded part like this. Comes in black, light grey or cream beige.
Before you wear it
When to leave it off, and when to ask someone
This is a compression product, and compression is not right for every leg. Please read this bit properly.
- Talk to a clinician first if you have circulation problems, diabetes, varicose veins, a history of blood clots, reduced sensation in the leg, or fragile skin.
- Do not use it on an undiagnosed acute injury. A knee that swelled suddenly, locked, gave way or took a direct blow needs looking at before it needs strapping.
- Take it off if anything changes below it. Numbness, tingling, pins and needles, coldness, colour change or new swelling in the calf, ankle or foot all mean loosen it or remove it. A tightly worn strap has been reported, in at least one published case, ahead of a blood clot forming — rare, but a reason to keep it snug rather than tight and to take it off when you are not moving.
- Wear it for activity, not around the clock. There is no evidence for all-day use, and skin irritation under knee orthoses is a documented nuisance in the trials.
- Stop if pain gets worse with it on, or if pain persists once you take it off.
Nothing here is medical advice, and this band is not a diagnosis. If your knee has been hurting for weeks, the most useful thing you can buy is twenty minutes with a physiotherapist.

What arrives
Choosing a two-pack gets you two complete bands of the same colour, one for each knee.
