Yoga for knee pain

Yoga for knee pain helps, moderately, and it is not better than the boring alternative. That is the whole finding, and the size of it is worth knowing before you start. Most of the trial evidence is in knee osteoarthritis, which is what the great majority of persistent Indian knee pain after 45 turns out to be.

The 2024 systematic review and meta-analysis in PLoS One pooled eight randomised trials and 756 people with knee osteoarthritis. Against control, yoga improved pain with a standardised mean difference of 0.92, stiffness by 0.51 and physical function by 0.53. Those are respectable numbers. The same analysis found no significant improvement in activities of daily living or in quality of life, and the reviewers were careful to say so. So the joint feels better and moves better, and whether your week is measurably different is not established.

Then the comparison that matters. A 2025 randomised trial in JAMA Network Open put 117 people with knee osteoarthritis into twelve weeks of either yoga or straightforward strengthening exercise. The between group difference in knee pain was 1.1 mm on a 100 mm scale, with a confidence interval running from minus 7.8 to plus 5.7. In plain words: no difference worth having, and yoga was non inferior to strengthening. Neither beat the other.

That result is more useful than a win would have been. It means the question is not whether yoga is the right treatment for your knee, but whether it is the exercise you will still be doing in March. Strengthening works and almost nobody keeps it up alone. A class you like, with people you know, is the version of leg strengthening that survives contact with real life. It may support a painful knee alongside proper medical care. It does not repair cartilage, and no posture reverses osteoarthritis.

One more number belongs at the top of this page, because it is the reason the next section exists. In a study of deep squatting in healthy young Indian adults, peak tibiofemoral joint contact force reached about 5.9 times body weight with the heels down and 5.3 times with the heels lifted. And a German case control study of 295 men with knee osteoarthritis and 327 controls found that cumulative kneeling or squatting beyond 10,800 hours carried an odds ratio of 2.4 for the disease. Deep knee flexion under load is not neutral. Yoga is full of it.

Every ranking page on yoga for knee pain half admits this and then gives you the poses anyway. Here it is without the hedging. Four families of posture are the ones Indian students with knees get hurt in, and the reason is the same in all four: deep knee flexion, taken under body weight, held for minutes, in a joint that already has a wearing surface.

• Deep squats. Malasana, and any pose that asks the heels towards the seat under load. This is the big one, and it is culturally awkward to say in India because squatting is how a great many people have sat, cooked and used a bathroom their whole lives. The measured joint contact force in a full squat is close to six times body weight. If your knee is already sore, that is not the load to add on purpose for a minute at a time. Squatting to pick something up is life. Squatting as a held posture is a choice.
• Lotus. Padmasana, and half lotus too. Lotus is a hip rotation pose that people perform with their knees, because the hips will not do it and the knee is the joint that gives. The force lands on the inner side of the knee, exactly where the medial meniscus and the medial collateral ligament are, and it is the single most common way I have seen a student hurt a knee in a yoga hall in forty years. It looks like the point of yoga. It is not the point of yoga.
• Hero pose. Virasana, sitting between the heels with the shins turned out. There is no gentle version of this for a knee with a problem. It combines full flexion with rotation at the joint and then holds it while you breathe, which is precisely the combination a torn or thinning meniscus objects to. The kneeling seat vajrasana is the same difficulty in a milder form, and Indian students often assume it is safe because it is traditional and ordinary. It is neither easy nor harmless on a sore knee.
• Kneeling without padding, for anything at all. Cat and cow, table top, low lunges, any transition through the knees. The problem here is not the pose, it is the floor. A bony kneecap on a thin mat on a stone or tiled hall floor is a bursitis waiting to happen, and it is the most preventable knee complaint in yoga because the answer costs nothing. Fold a blanket. Fold two.

Two more, briefly. Utkatasana at any real depth is a held squat with the same arithmetic as the first bullet, so it belongs on the list until the knee is quiet and then belongs back only at a shallow depth against a wall. And garudasana with the legs wrapped combines flexion, rotation and standing on one leg, and I do not teach the leg version to anybody with knee pain at all.

None of this means stop moving. Every one of these has a replacement in the table below, and the replacements are where the trial benefit actually came from.

The whole page in one table. Two from the practise column for a fortnight, then add one a week, and read the avoid column as the more important half for the first month.

The avoid column is not permanent for malasana, vajrasana or utkatasana. It is permanent for lotus and hero pose in a knee that has already been injured, and I would rather say that plainly than leave it to be discovered.

What is left is not a consolation prize. It is, almost exactly, the strengthening programme that matched yoga in the JAMA trial, done in postures.

• Tadasana, weight deliberately even. One sore knee produces a limp, the limp becomes a habit, and the habit outlives the original injury by years. This is where it is found.
• Virabhadrasana 2, front knee over the ankle. Quadriceps and gluteal strength has the best evidence of anything in knee osteoarthritis, and this is the standing pose that trains it without deep flexion.
• Setu bandhasana, lifted low, five times. A weak hip abductor lets the pelvis drop on every step and the knee takes the sideways force. Fix the hip and the knee complains less, which surprises people who expected knee exercises.
• Supta matsyendrasana, supported. The outer thigh and the band running down it pull the kneecap sideways in its groove when they are tight, and this is the lying release that does not load the joint.
• Dandasana with a rolled towel behind the knees, pressing down for five breaths. This is the safest full quadriceps contraction in yoga and it is available on the first day, even in a flare.
• Savasana, eight minutes, calves on a chair. Guarding is muscular, and it only lets go when nothing is being asked of the leg.
• Nadi shodhana, eight rounds, sitting on a chair. Not for the knee. For the year of expecting the knee to hurt.

Short holds, repeated, rather than long holds. Thirty seconds twice beats two minutes once, and in a joint with a wearing surface that is not a technicality.

Most persistent knee pain in an adult over 45 is osteoarthritis and movement is part of the treatment. Some knee pain is not. Stop and see a doctor before any class if:

• The knee is hot, swollen and red, particularly with a fever. That can be an infected joint and it is a same day problem.
• The knee locks, catches or gives way, or you cannot fully straighten it. That suggests something mechanical inside the joint.
• The pain began with a twist, a pop or a fall, and the knee swelled within a few hours.
• There is calf pain, calf swelling or one leg warmer than the other, especially after a flight, an illness or surgery.
• The knee has been progressively worse for months and now hurts at rest and at night.
• You have had a knee replacement. Practice after a replacement is usually good, and the depth of flexion allowed is set by the surgeon, not by a page.
• There is numbness or weakness in the foot, or pain that runs from the back down past the knee, which is a spinal question rather than a knee one.

None of that is a reason to give up on yoga. It is a reason to know what you are treating first.

Week one to two: stiffness eases before pain does, and the first thing most people notice is that the knee is less reluctant in the morning rather than less sore in the evening. Some mild ache after the first two or three sessions is normal and should settle within a day.

Week three to six: this is where thigh strength starts to arrive, and where stairs change. Going up improves before coming down does, because coming down is the harder demand on the joint.

Week eight to twelve: the trial window. This is where the pain and function numbers in the meta-analysis were measured, and where a knee that was avoiding a flight of stairs usually stops avoiding it. Expect improvement, not resolution.

Beyond three months: the strength holds while the practice holds, and it fades within about two months of stopping, which is the honest reason a weekly class matters more than a hard first six weeks. The trials that followed people up watched the benefit go when the classes stopped.

Write these on the first day and again every four weeks. They are more use than how the knee feels on a given morning, which depends on the weather and on yesterday.

1. Sit to stands from a dining chair in thirty seconds, arms folded. This is the single best proxy for thigh strength you can do at home, and it is the number the practice is actually trying to move.
2. Stairs, in two parts. Can you go up one flight without holding the rail, and can you come down one flight without holding it. Note them separately. Down improving is the bigger milestone.
3. Worst pain in the past week, nought to ten, and how many days out of seven the knee was noticeable at all. The second half of that is what changes first, and people miss it because they only ever record the worst day.

Three numbers, four weekly. Bring them to class. A student who says the sit to stand count went from eight to twelve gets a different session from one who says the knee still hurts.

The specific reason to have a teacher for a knee is that the mistake is invisible to the person making it. A front knee drifting inwards in a standing pose, a foot rolling flat, a kneecap tracking off line, a hip dropping on every step: none of that can be felt, all of it can be seen from the side in about two seconds, and every one of them puts the load in the wrong place. That is the case for a room with someone in it rather than a video. Not motivation, correction.

The classes here are traditional yoga taught slowly by one teacher across about forty years, at a residents' association hall, to students of all ages, in person and live online. If you have been searching for yoga for knee pain near you, the in person classes run in north Bangalore, in the hall at MSR Nagar, with students coming from Mathikere, Malleswaram and Yeshwanthpur. Chairs and folded blankets are there for anybody who wants them, and nobody is asked to sit on the floor cross legged to breathe. If a knee makes travelling to a hall the worst part of the day, the live online classes work well here, because a camera set side on shows a drifting knee more clearly than a teacher at the front of a hall ever could. The first class is free. Come and say which knee, and whether it is stairs up or stairs down.
