Surya Namaskar is practiced by millions of Indians every morning — in parks across Noida and Greater Noida, on apartment terraces, and in yoga classes that have proliferated enormously over the last decade. It is one of those practices with deeply positive associations: discipline, health, spiritual connection, the rhythm of a good morning.
And then the knee starts hurting. The question that follows — asked quietly, sometimes with the anxiety of someone considering giving up something important — is whether Surya Namaskar is causing the damage or is safe to continue.
The honest answer, from an orthopedic perspective, is: it depends on which poses you are doing, how you are doing them, and what the state of your knee actually is.
This guide goes pose by pose through Surya Namaskar and assesses each position from a clinical standpoint — specifically for patients with knee osteoarthritis, which is the most common knee condition in adults over 40 in India. The guidance differs for patients with meniscal tears, post-surgical knees, and other conditions; those cases need individual assessment.
First: Understanding What Hurts a Knee with Arthritis
Knee osteoarthritis is cartilage loss — the smooth surface covering the bone ends wears away, and what remains is rougher, thinner, and more pain-sensitive. Understanding which loads stress the arthritic knee helps predict which yoga poses are problematic.
The positions that generate the highest compressive load on an arthritic knee:
- Deep knee flexion beyond 90 degrees — high-load on the posterior cartilage and patellofemoral joint
- Full weight-bearing deep squatting — combines high compressive load with rotational stress
- Half-kneeling and full kneeling — direct load on the anterior knee and kneecap
The positions that are generally manageable:
- Standing positions with the knee in slight to moderate flexion (30 to 60 degrees)
- Hip-dominated movements where the knee is relatively passive
- Positions where the weight is through the arms and the knee is unloaded
With this framework in mind, let us assess each pose in the traditional 12-position Surya Namaskar sequence.
The 12 Poses: Clinical Assessment
Position 1 — Pranamasana (Prayer Pose)
The position: Standing upright, feet together, hands in namaste at chest.
Clinical assessment: ✅ Completely safe. Upright standing with a neutral knee position. No load of concern.
Position 2 — Hastauttanasana (Raised Arms Pose)
The position: Arms extended overhead, slight backward bend at the upper back.
Clinical assessment: ✅ Completely safe. The knee remains in a near-neutral position. No concern.
Position 3 — Hastapadasana (Hand to Foot Pose)
The position: Forward bend reaching hands toward the floor, knees either straight or slightly bent.
Clinical assessment: ⚠️ Moderate caution. If the knees are kept straight (legs extended), this is a hamstring stretch with minimal knee loading — manageable. If the knees are bent deeply to allow the hands to reach the floor (which many patients with tight hamstrings do), this creates moderate knee flexion under load, which stresses the patellofemoral joint. Recommendation: bend the knees to a comfortable, shallow angle (30 to 45 degrees) rather than deeply. Do not push the knee into pain attempting to reach the floor.
Position 4 — Ashwa Sanchalanasana (Equestrian Pose)
The position: One foot forward (lunge position), back knee on the ground or hovering, hands on the mat.
Clinical assessment: ⚠️ Significant attention required — one of the most important positions to assess.
The front knee in this position is in approximately 90 degrees of flexion under partial body weight — this is a moderate but manageable load for mild-to-moderate arthritis. The concern is the back leg: if the back knee rests on the ground, there is direct load on the kneecap of the back leg. For patients with significant knee arthritis or patellofemoral pain, kneeling with the back knee on the floor is uncomfortable to painful. Modification: use a folded blanket under the back knee to reduce direct pressure, or keep the back knee hovering if strength allows.
Position 5 — Dandasana (Stick/Plank Pose)
The position: Full body extended plank, weight through hands and toes.
Clinical assessment: ✅ Very good for arthritic knees. The knee is in near-full extension and unloaded — the weight is through the arms. This position is typically entirely manageable. If wrist or shoulder issues are present, those are the limiting factors, not the knee.
Position 6 — Ashtanga Namaskara (Eight Limbs Pose)
The position: Knees, chest, and chin touch the ground simultaneously while keeping the hips slightly raised.
Clinical assessment: ⚠️ The knees touch the ground in this position — direct contact of the kneecap area with the floor. For patients with significant patellofemoral arthritis or prepatellar bursitis, this can be uncomfortable. A folded blanket under the knees reduces pressure substantially. The actual load through the joint while in this position is low — the concern is mainly contact pressure, not compressive loading.
Position 7 — Bhujangasana (Cobra Pose)
The position: Lying face down, hands under shoulders, lifting the chest off the ground. Legs extended behind.
Clinical assessment: ✅ Completely safe for the knee. The knee is in full extension and passively resting on the mat. This is also a useful position for opening the hip flexors — tight hip flexors are a common contributor to knee pain by altering walking mechanics.
Position 8 — Adho Mukha Svanasana (Downward Dog)
The position: Inverted V shape — hands and feet on the ground, hips raised.
Clinical assessment: ✅ Generally good. The knee is in near-full extension, weight is distributed between hands and feet. If tight hamstrings prevent full knee extension, a mild bend in the knees is appropriate — do not lock into deep flexion. If heel tendons are very tight (the heels cannot reach the floor), bending the knees gently to allow the spine to lengthen is more important than forcing the heels down.
Position 9 — Ashwa Sanchalanasana (Equestrian, Other Side)
The position: Same as Position 4, other leg forward.
Clinical assessment: Same as Position 4 — manage accordingly. The more arthritic knee should be the one considered more carefully when placing the back leg.
Position 10 — Hastapadasana (Hand to Foot Pose, repeated)
The position: Same as Position 3.
Clinical assessment: Same as Position 3.
Position 11 — Hastauttanasana (Raised Arms, repeated)
The position: Same as Position 2.
Clinical assessment: ✅ Safe.
Position 12 — Pranamasana (Prayer, completing the round)
The position: Return to upright standing, namaste.
Clinical assessment: ✅ Safe.
The Two Positions That Deserve Extra Attention
The Transition Between Position 8 and 9 (Downward Dog to Lunge)
This transition — stepping one foot forward from downward dog into the lunge — involves a dynamic moment where the front foot swings through and the back knee comes close to or touches the ground. For patients with significant knee arthritis, this transition can be the most uncomfortable part of the sequence. Modification: step the foot through slowly (rather than swinging it) and place it mindfully. Alternatively, from downward dog, bring the knee to the ground first and then step the foot forward with control.
The Transition Between Position 4 (or 9) and Position 5 (Lunge to Plank)
Straightening from the lunge to the plank position requires the back leg to extend while pushing through the front foot. This dynamic extension under load can be uncomfortable for the front knee. Modification: keep the movement slow and controlled, using the arms to take significant weight during the transition.
When Surya Namaskar Should Be Avoided or Significantly Modified
Patients in the following situations should not practice traditional Surya Namaskar without specific guidance:
Severe knee arthritis (Grade 3-4 on X-ray, bone-on-bone contact, significant deformity): The deep flexion and kneeling positions load an already maximally damaged joint. Modified yoga or chair yoga is more appropriate.
Active knee inflammation/flare: During a painful flare with swelling and warmth, any significant loading is counterproductive. Rest the joint until the acute flare settles.
Recent knee surgery (within 3-6 months): ACL reconstruction, meniscal repair, and knee replacement all require specific post-operative exercise guidance. Surya Namaskar is not appropriate in the early recovery phase without physiotherapy clearance.
Significant meniscal tears: Kneeling and deep flexion load the meniscus under maximum compression. Patients with large meniscal tears or recent meniscal symptoms should avoid positions 4, 6, and 9 until the meniscal issue is evaluated and managed.
Modifications That Make Surya Namaskar Knee-Friendly
For patients with mild to moderate knee arthritis who want to continue practicing:
Use a blanket under the knees for positions 4, 6, and 9 where the knee contacts the floor. This single modification removes the contact pressure that makes many patients uncomfortable.
Reduce the depth of the forward bend in positions 3 and 10. A shallow bend (45 degrees) rather than touching the floor maintains the practice while reducing patellofemoral load.
Practice at a slower pace. Dynamic, fast Surya Namaskar repetitions generate higher joint loads than slow, held positions. For arthritic patients, slow and mindful is better than vigorous.
Use a chair for support in the standing transitions for patients with balance concerns or higher arthritis grades.
Replace Ashtanga Namaskara (Position 6) with Chaturanga or Plank for patients where the kneeling position is the main source of discomfort.
The Broader Picture: Is Yoga Good for Arthritis?
Yes — with the right approach. Yoga's benefits for knee arthritis include: improved muscle strength around the joint, better balance and proprioception (joint position sense), improved flexibility of the hip flexors and hamstrings (both of which affect knee mechanics), and the well-documented psychological benefits of mindful movement and breathwork.
Multiple randomised controlled trials have shown that appropriately adapted yoga reduces knee arthritis pain and improves function. The key word is adapted — the practice needs to account for the joint's current state, not simply continue what was done when the joint was healthy.
Dr. Ankur Singh advises patients with knee arthritis who want to continue yoga to have a clinical assessment to establish exactly which grade of arthritis they have and which positions are appropriate at their current stage.

Frequently Asked Questions
Can I do Surya Namaskar after knee replacement?
Not in the traditional form for at least 6 months post-surgery. After 6 months, with Dr. Ankur Singh's clearance, a carefully modified practice avoiding deep flexion and kneeling may be possible. This needs individual assessment.
Should I stop Surya Namaskar if my knee aches afterward?
Mild aching that resolves within 24 hours is generally acceptable — the joint is working and some response is expected. If the aching persists for more than 24 to 48 hours, or if there is any swelling, reduce the range or number of repetitions and assess whether the specific positions are appropriate.
Is Surya Namaskar better for knees than running?
Yes, in most cases. Traditional Surya Namaskar generates lower peak knee loads than running, which involves significant impact. Modified Surya Namaskar is generally a better option than running for patients with early-to-moderate knee arthritis.
