Red light therapy for knee pain
A stiff, grumbling knee is the single most common reason people try a red light wrap. Here is how to do it properly, and what not to expect.
Why knees respond well to a wrap
The knee is close to the surface. There is very little muscle between skin and joint compared with a hip, which means near-infrared light at 850nm has a realistic chance of reaching the tissue that actually aches. It is also an easy joint to wrap: the strap goes round, the panel sits flat, and you can sit down for the whole session.
Where to put the panel
- General ache and stiffness: centre the panel over the front of the knee, just below the kneecap.
- Inner-knee pain: rotate the wrap so the lit panel sits over the inside of the joint.
- Behind the knee: fasten it the other way round so the panel sits in the hollow behind the joint, and keep the leg slightly bent.
Always against bare skin. Trousers, tights or even a thin sock over the area will absorb most of the light before it reaches you.
How long, how often
Twenty minutes a day. That is the whole prescription. There is no advantage to doubling the session, and LumaWrap counts down and shuts off on its own so you cannot accidentally overdo it.
If both knees hurt, treat one per session or order two wraps and do both at once — the two-wrap bundle exists mostly for this reason.
How soon you will know
Expect very little in the first week beyond a nice warmth. Reduced stiffness usually arrives before reduced pain, somewhere in the second week. The clearer change tends to land between weeks four and six. If you are still feeling nothing at all by week eight of daily use, it is probably not going to work for your knee — which is what the 90-day refund is for.
When to see a GP instead
A red light wrap is for a long-running ache, not a new injury. See a doctor if the knee is hot and swollen, if it locks or gives way, if the pain came on suddenly after a fall, or if you have a fever alongside it.
Common questions
Does red light therapy work for knee pain?+
Red and near-infrared light therapy is widely used for joint aches and stiffness. It is not a painkiller and results are gradual, building over four to six weeks of daily use rather than appearing in a single session.
How long should I use red light therapy on my knee?+
Twenty minutes a day on bare skin over the knee. Longer sessions do not add benefit, which is why LumaWrap switches itself off at twenty minutes.
Where exactly should the wrap sit on the knee?+
Centre the lit panel over the front of the knee, just below the kneecap, and fasten the strap snugly behind the joint. If the ache is on the inner side, shift the panel that way.
Can I use it if I have had a knee replacement?+
Speak to your GP or surgeon first. Light therapy over an implant is not automatically a problem, but it is a conversation to have with the person who knows your knee.
