Knee osteoarthritis affects hundreds of millions of people worldwide, and for years the standard exercise prescription has centred on strengthening the muscles that support the joint. New research suggests a gentler alternative can hold its own. A randomized clinical trial published in 2025 found that a structured yoga program reduced knee pain about as effectively as a conventional strengthening routine over 12 weeks — a result that could reshape how people with aching knees think about movement.
The timing is fitting. With International Day of Yoga 2026 and its theme of “Yoga for Healthy Ageing” just behind us, attention has turned to how joint-friendly movement keeps people mobile as they grow older. Knee osteoarthritis is one of the biggest threats to that independence, so evidence that yoga can ease it deserves a closer look.
What the Research Actually Found
The 2025 trial recruited adults aged 40 and over with knee osteoarthritis in Southern Tasmania, Australia, and randomly assigned them to a 12-week yoga program or a conventional strengthening-exercise program. Both groups improved, and crucially the yoga group’s reduction in knee pain was comparable to the strengthening group’s. Because this was a head-to-head comparison against an active, evidence-based treatment rather than against doing nothing, the finding carries more weight than a simple yoga-versus-waitlist study.
That trial builds on a 2024 systematic review and meta-analysis that pooled eight randomized controlled trials involving 756 people with knee osteoarthritis. Compared with control groups, yoga produced significant improvements in pain, stiffness and physical function. The review was more cautious about gains in everyday activities and overall quality of life, where the evidence was mixed — a reminder that yoga helps with symptoms but is not a cure-all.
These results sit comfortably alongside the wider evidence base. The U.S. National Center for Complementary and Integrative Health notes that yoga has reasonable evidence for improving pain and function in conditions such as osteoarthritis and chronic low-back pain. Researchers think the benefit comes from a combination of effects: yoga gently strengthens the muscles around the knee — especially the quadriceps and hips — while also improving flexibility, balance and body awareness, and using breath and relaxation to turn down the nervous system’s pain response.
Why This Matters for Knee Arthritis
The most practical implication is choice. Strengthening exercise works, but many people find repetitive resistance drills tedious and quietly abandon them. If yoga delivers similar pain relief, it gives patients a second evidence-based option that some will find more enjoyable and easier to sustain — and adherence is where most exercise plans succeed or fail.
Yoga also brings benefits that a knee-focused strength routine usually does not. Regular practice is linked with better mood, sleep and stress levels, all of which influence how intensely we feel chronic pain. For older adults in particular, the balance and proprioception that yoga builds can reduce the risk of falls, a major cause of injury later in life. It is low-cost, needs little equipment and can be scaled to almost any ability.
A caveat matters here: yoga complements medical care rather than replacing it, and technique is everything when a joint is already irritated. Deep knee bends, aggressive lunges and poses that load a flexed, weight-bearing knee can aggravate symptoms. The studies that show benefit used structured, often therapeutically adapted programs — not a generic vigorous class.
5 Knee-Friendly Yoga Poses to Try
The poses below emphasise gentle strengthening, alignment and balance while keeping load off an inflamed knee. Move slowly, stop if anything sharpens, and use props freely.
- Mountain Pose (Tadasana): The foundation. Standing tall with feet hip-width and the kneecaps lifting softly teaches the alignment that protects the joint in every other pose.
- Chair Pose (Utkatasana), shallow version: Bend the knees only slightly and keep them tracking over the ankles, never past the toes. Even a small range builds the quadriceps strength that stabilises an arthritic knee.
- Supported Bridge (Setu Bandhasana): Lying on your back and lifting the hips strengthens the glutes and hamstrings, off-loading the knee while building the hip support it relies on.
- Reclined Hand-to-Big-Toe (Supta Padangusthasana): Using a strap around the foot, this gently stretches the hamstrings and calves with the spine supported and no weight on the knee.
- Tree Pose (Vrksasana): A balance pose that sharpens proprioception. Keep a chair or wall nearby and avoid pressing the lifted foot into the side of the standing knee.
What This Means for You
If you have knee osteoarthritis and want to try yoga, the research points to a clear, realistic plan. Aim for roughly two to three sessions a week and give it eight to twelve weeks — that is the window in which most trials begin to report measurable improvement. Favour gentle, restorative or therapeutically oriented styles over fast, heated classes, and tell your teacher about your knee so they can offer modifications. If you are new to the mat, our guide to yoga for beginners is a good starting point, and our gentle yoga sequences are easier on sensitive joints.
Listen to your knee rather than pushing through pain, and use props — blocks, straps, a folded blanket under the knee — to reduce strain. Yoga can also help with the aches that often travel alongside knee trouble; if your discomfort radiates, our guides to yoga for joint pain and yoga for back pain offer complementary sequences. Most importantly, check with your doctor or a physiotherapist before starting, especially if your arthritis is advanced or you have had knee surgery.
Key Takeaways
- A 2025 randomized trial found yoga reduced knee osteoarthritis pain about as well as conventional strengthening exercise over 12 weeks.
- A 2024 meta-analysis of eight trials (756 patients) found yoga significantly improved pain, stiffness and physical function.
- Yoga’s edge may be adherence plus added benefits for mood, sleep, stress and balance.
- Technique matters: choose gentle, adapted practice, avoid deep loaded knee bends, and use props.
- Aim for 2–3 sessions a week over 8–12 weeks, and treat yoga as a complement to medical care, not a replacement.
How Yoga Stacks Up Against Other Options
It helps to put yoga in context. For knee osteoarthritis, guidelines from bodies such as the American College of Rheumatology consistently rank exercise and weight management as first-line treatments, ahead of most medications and well ahead of surgery for early disease. Within that exercise umbrella, strengthening and aerobic work have the deepest research base. What the latest yoga trials add is evidence that a mind-body practice can sit in the same tier rather than being dismissed as a soft alternative.
That matters because no single form of movement suits everyone. Some people thrive on resistance machines or stationary cycling; others find those routines joyless and stop within weeks. Offering yoga as a legitimate, evidence-supported choice widens the net, and for many it can be combined with short strength sessions for the best of both — the muscle-building stimulus of resistance work and the mobility, balance and stress relief of yoga.
What We Still Do Not Know
The research is encouraging but not the final word. Many yoga trials are relatively small, use different styles and durations, and rarely follow participants for years, so questions remain about how long the benefits last and whether yoga can slow the structural progression of arthritis rather than simply easing symptoms. Blinding is also difficult: people know whether they are doing yoga, which can influence how they report pain. Larger, longer studies that standardise the practice will help clarify exactly how much yoga helps, for whom, and at what dose — but the current evidence is already strong enough to make it a reasonable thing to try.
