Overview
Knee osteoarthritis (OA) is the most common joint disease in India, affecting approximately 15% of the population over 60 — with over 4 crore Indians living with knee OA at any given time. It is a condition in which the protective cartilage cushioning the ends of the bones in the knee progressively wears down, causing pain, swelling, stiffness, and a characteristic grating or crunching sensation on movement. Critically, knee OA pain does not always correlate with radiological (X-ray) severity — many people with severe changes on imaging have mild symptoms, and vice versa. This is why physiotherapy, which addresses the muscular and neuromuscular causes of pain rather than the structural changes, produces outstanding results across all grades of knee OA, including Grade 3. At Curis 360 in Bengaluru, our knee OA programme has helped hundreds of patients reduce pain significantly and delay or entirely avoid total knee replacement.
Common Symptoms
- Deep, aching pain in the knee that is typically worse with activity and relieved by rest in early stages.
- Morning stiffness in the knee lasting less than 30 minutes — a hallmark distinguishing OA from inflammatory arthritis.
- A crunching, grinding, or crackling sound (crepitus) when bending or straightening the knee.
- Swelling around the knee joint, especially after prolonged walking or stair climbing.
- Reduced range of motion — difficulty fully bending or straightening the knee.
- A feeling of the knee 'locking' or 'giving way' when the joint catches on irregular cartilage.
- Bony enlargement or deformity around the knee, visible in advanced cases.
- Increased pain in cold or damp weather, a commonly reported symptom.
Primary Causes
- Age-related cartilage degeneration — cartilage loses its water content and resilience after age 45.
- Obesity and excess body weight — every 1 kg of body weight adds approximately 4 kg of compressive force on the knee during walking.
- Previous knee injuries — ACL tears, meniscus damage, and fractures significantly increase lifetime OA risk.
- Quadriceps muscle weakness — weak quads fail to absorb shock, transferring excessive load to the cartilage.
- Occupational hazards — repeated squatting, kneeling, and heavy lifting in professions common in Bengaluru's manufacturing and construction sectors.
- Genetic predisposition, with a 40–65% heritability for knee OA.
- Varus deformity (bow-legged alignment), which overloads the medial compartment of the knee.
Why Exercise Is the Most Powerful Treatment for Knee OA — and Why Most Patients Don't Do It
The most comprehensive systematic review of knee OA treatment — the 2021 OARSI Guidelines — ranks land-based exercise as the single most evidence-based intervention for knee osteoarthritis, ahead of anti-inflammatory medications, knee braces, and injections. Yet fewer than 20% of knee OA patients in India receive structured physiotherapy. The reason is a widespread misconception: that moving a 'worn-out' joint will accelerate damage.
The science is clear and opposite: cartilage has no direct blood supply and receives its nutrients through the compression and release that occurs with movement. Immobility starves cartilage cells of nutrition, accelerating degeneration. Structured exercise, by contrast, stimulates synovial fluid production, reduces inflammatory cytokines within the joint, and — most importantly — builds the muscular 'sleeve' around the knee that protects the cartilage from impact loading.
At Curis 360, every knee OA patient begins with a detailed strength assessment. Research shows that quadriceps weakness is the single most modifiable risk factor for knee OA progression. Increasing quadriceps strength by just 20% can reduce knee pain by up to 30% in patients with Grade 2–3 OA.
Physiotherapy vs. Knee Replacement Surgery: What the Evidence Says
A landmark 2020 study in the New England Journal of Medicine found that total knee replacement (TKR) combined with physiotherapy offered no better outcomes at 12 months than physiotherapy alone for patients with moderate-to-severe knee OA. Two years after the trial, approximately one-third of patients who were originally assigned to physiotherapy had changed their mind and chosen surgery — but two-thirds had not, and were functioning equally well.
This does not mean surgery is wrong — for end-stage OA with bone-on-bone contact and severe functional limitation, TKR is a highly effective and appropriate intervention. But it does mean that surgery should not be the first or only option considered for Grade 1–3 OA. Many patients in Bengaluru proceed to surgery prematurely, without ever completing a quality physiotherapy programme.
At Curis 360, our standard recommendation is a minimum 3-month structured physiotherapy programme before any orthopaedic surgical referral, unless the patient has already failed quality physiotherapy or has Grade 4 (bone-on-bone) OA with severe pain at rest.
The Curis 360 Knee OA Programme: What Happens in Your Sessions
Initial Assessment (Session 1): A detailed joint assessment including range of motion measurement, muscle strength grading, gait analysis, and X-ray review. We grade your OA severity (Kellgren-Lawrence Grade 1–4) and set realistic recovery milestones. A personalised home exercise programme is provided from Day 1.
Weeks 1–3 (Pain Control Phase): Manual therapy to the knee and hip, McConnell patellar taping to offload the patellofemoral joint, TENS for pain relief, and gentle range-of-motion exercises. The goal is achieving pain-free walking on a flat surface.
Weeks 4–8 (Strengthening Phase): Progressive quadriceps and VMO strengthening — wall slides, step-ups, terminal knee extensions, and cycling. Hip abductor and external rotator strengthening is included, as hip weakness is consistently shown to contribute to medial knee load.
Weeks 9–12 (Functional Phase): Stair training, balance exercises, walking retraining on inclines, and activity-specific exercises. For patients in Bengaluru who participate in activities like temple visits with stairs or household activities involving floor-sitting, we specifically train these functional patterns.
Managing Knee OA in Bengaluru's Climate and Lifestyle
Bengaluru's typically cool climate is generally favourable for knee OA — warm and humid conditions tend to worsen joint pain, whereas cooler temperatures are often better tolerated. However, the monsoon season (June–September) brings humidity spikes that many OA patients report as a pain trigger. We advise patients to continue their exercise programme indoors during heavy rains rather than taking rest days.
Diet and weight management are integral to our knee OA programme. A loss of just 5% body weight in overweight patients produces a clinically significant reduction in knee pain. Our physiotherapists provide practical, Bengaluru-specific dietary advice — including anti-inflammatory eating patterns compatible with South Indian and North Indian dietary preferences.
Frequently Asked Questions
Can physiotherapy cure knee osteoarthritis?
Physiotherapy cannot reverse the structural changes of knee osteoarthritis — the cartilage loss is permanent. However, physiotherapy can very effectively control pain, improve function, slow progression, and in many cases prevent the need for surgery. Studies show 40–70% of knee OA patients achieve long-term pain relief and improved quality of life with physiotherapy alone. The goal is not to 'cure' the structural change but to make the joint functionally painless and strong.
Which exercise is best for knee osteoarthritis?
The three most evidence-based exercises for knee OA are: (1) Straight Leg Raises — builds quadriceps strength without joint compression, ideal for Grade 3–4 OA with severe pain. (2) Step-ups — functional strength training with controllable load. (3) Stationary cycling — low-impact cardiovascular exercise that lubricates the joint with synovial fluid without cartilage compression. Walking is also strongly recommended but should be on flat surfaces and limited to pain-free duration in the early stages.
Is walking good or bad for knee osteoarthritis?
Walking is good for knee osteoarthritis, with conditions. Short, frequent walks on flat surfaces are beneficial — they stimulate cartilage nutrition, strengthen the muscles around the knee, and maintain joint mobility. The key principle is 'pain as a guide': walking that causes pain above a 4/10 should be reduced in duration or replaced with swimming or cycling until strength improves. Avoid prolonged walking on uneven surfaces, stairs, or inclines in the early stages of treatment.
At what grade of knee OA should I consider surgery?
Knee replacement surgery is generally recommended for Grade 4 (bone-on-bone) OA with severe, constant pain that significantly limits daily activities and has not responded to at least 3–6 months of quality physiotherapy, anti-inflammatory medications, and lifestyle modification. Grades 1–3 OA should be managed conservatively with physiotherapy as the primary treatment. However, the decision is individual — age, weight, occupation, and functional goals all factor into the recommendation.
How many physiotherapy sessions are needed for knee OA in Bengaluru?
At Curis 360 in Bengaluru, most knee OA patients see significant improvement within 12–18 sessions over 6–8 weeks. We typically recommend a programme of 3 sessions per week for the first 3 weeks, then 2 sessions per week for 3 weeks, tapering to 1 session per week as the patient becomes independent with their home programme. Chronic or Grade 3–4 OA may benefit from a longer maintenance programme. Sessions start at ₹800. Call +917899844360.
Are cortisone injections better than physiotherapy for knee OA?
Cortisone (steroid) injections provide faster short-term pain relief than physiotherapy — typically within 1–2 weeks — but the effects usually last only 4–8 weeks and may accelerate cartilage breakdown with repeated use. Physiotherapy takes longer to show results (4–6 weeks) but produces lasting improvements in strength and function that injections cannot. The most effective approach is often a combination: an injection to reduce acute flare-up pain enough to allow participation in a physiotherapy programme.
Stop living with Knee Osteoarthritis
Our targeted physiotherapy protocols typically resolve this in 6 to 12 weeks for significant pain reduction.
