Can knee pain be treated without surgery?

Yes — in 60–70% of Grade 1–3 knee arthritis cases, evidence-based conservative treatment (structured physiotherapy, weight loss, low-impact exercise, PRP for suitable cases, walking aids, bracing) can avoid or significantly delay replacement. Grade 4 with limiting symptoms usually requires surgery.

Does glucosamine work for knee pain?

No — multiple high-quality RCTs (including the NIH-funded GAIT trial) show no benefit over placebo for knee OA. Despite billions spent globally each year on glucosamine and chondroitin, the evidence is clear: it doesn't work.

Does PRP work for knee arthritis?

Yes for Grade 2–3 OA — 60–70% of suitable patients get 6–12 months of significant pain relief. No for Grade 4 bone-on-bone arthritis, where surgery is needed. Multiple RCTs and meta-analyses support PRP for early-to-mid OA.

Are stem cell injections effective for knee arthritis?

Current evidence (2025) doesn't support routine stem cell injections for knee OA — preparations vary widely, results are inconsistent, and costs are significant. The science may evolve, but at present PRP has stronger evidence at lower cost.

How long should I try non-surgical treatment before considering surgery?

At least 3–6 months of structured conservative treatment for Grade 2–3 OA. Longer (6–12 months) if making partial progress. Surgery becomes appropriate when daily-activity-limiting pain persists despite proper conservative care, X-ray shows Grade 3–4 changes, and quality of life is substantially affected.

Is the Save the Knee Programme expensive?

Compared to surgery: dramatically less expensive. Programme components are billed individually — physiotherapy ₹500–1,500/session, PRP ₹6,000–15,000/injection, consultations standard rates. Most patients spend ₹30,000–1,00,000 over 6–12 months on conservative care, compared to ₹3–4 lakhs for replacement. Insurance generally doesn't cover PRP/HA but covers physiotherapy.

Why This Matters

Why This Guide Matters

India has the world's second-largest population of patients with knee arthritis. The orthopaedic industry is incentivised to recommend surgery. Patients are bombarded with claims about glucosamine, copper bracelets, magnetic therapy, "cartilage regeneration," stem cells, and other expensive interventions.

The honest answer: 60–70% of patients with Grade 1–3 knee arthritis can avoid or significantly delay surgery with the right combination of evidence-based interventions. The other 30–40% genuinely need replacement.

This guide tells you which is which.

What Works

What Actually Works — Strong Evidence

Strong evidence for:

Structured physiotherapy. Single most effective non-surgical intervention. Targeted quadriceps and hip strengthening for 6–12 weeks reduces pain and improves function in 70–80% of mild-to-moderate knee OA. Not generic exercise — specific, progressed, supervised.
Weight loss in overweight patients. Each kg of body weight = 4 kg of force across the knee while walking. Losing 5–10% of body weight reduces knee pain dramatically and slows OA progression. Hard to do but the most cost-effective intervention.
Low-impact exercise. Cycling, swimming, elliptical. Maintains knee flexibility and quad strength without joint loading. Recommended 150 minutes per week.
PRP (platelet-rich plasma) for Grade 2–3 OA. Multiple RCTs and meta-analyses support 6–12 months of pain relief in 60–70% of suitable patients. Not for Grade 4. PRP details →
Hyaluronic acid injections for Grade 2–3 OA. 4–6 months of pain relief in many patients. Not as strong as PRP evidence but reasonable second-line.
Cortisone injections for inflammatory flare-ups. Short-term pain relief (2–3 months). Limit to 2–3 per year — more frequent injections accelerate cartilage loss.
Patellar tracking braces for patellofemoral pain. Selected patients get substantial benefit.
Walking aids. A cane in the opposite hand reduces hip and knee load by up to 40%. Underused due to perceived stigma.

What Doesn't Work

What Doesn't Work — Despite Marketing

Strong evidence against (or no benefit shown):

Glucosamine and chondroitin supplements. Multiple high-quality RCTs (GAIT trial, NIH-funded) show no benefit over placebo for knee OA. Despite this, billions are spent globally each year. Save your money.
Copper bracelets and magnetic therapy. No mechanism, no evidence. Marketing only.
Most "cartilage regeneration" supplements. Cartilage doesn't regenerate from oral supplements. Period.
Stem cell injections (current state). No standardised preparation, no consistent evidence of benefit, and significant cost. Will likely be useful in some form in the future, but as of 2025, the evidence doesn't support routine use.
Arthroscopic "wash-out" for arthritis. Multiple RCTs (Moseley, Kirkley) show no benefit over sham surgery. Should not be done for OA without a clear mechanical indication (locked knee from meniscal flap).
Topical creams claiming "regeneration." Topical NSAIDs (diclofenac gel) work modestly for pain. Other creams — mostly marketing.

The Sequence

The Treatment Sequence That Works

For a typical patient with Grade 2–3 knee OA without mechanical symptoms (no locking, no giving way), here's the evidence-based sequence:

Months 0–3:

Structured physiotherapy 2–3 sessions/week.
Weight loss programme if BMI > 27.
Activity modification — substitute swimming and cycling for high-impact activities.
Topical NSAIDs for flare-ups.
Walking aid if needed.

Months 3–6 (if not improving enough):

PRP series (3 injections, 1–2 weeks apart) or hyaluronic acid.
Continue physiotherapy maintenance.
Patellar brace if patellofemoral component.

Months 6–12 (if still not adequately controlled):

Reassess imaging and symptoms.
Consider repeat PRP if previous injection helped.
Limited cortisone for severe flares.
Discuss surgery if quality of life remains substantially impacted.

If mechanical symptoms develop (locking, giving way), MRI and surgical consultation moves up the timeline.

Save the Knee

Save the Knee Programme

At Gini, we built the Save the Knee Programme to deliver this sequence as an integrated package. Patients work with:

An orthopaedic specialist for diagnosis and decision points.
A knee-specialist physiotherapist for structured rehab.
A nutritionist for weight management.
An imaging specialist for X-ray and (where indicated) MRI.
The team for PRP/HA injections when needed.

The honest goal: delay or avoid replacement in patients who don't yet need it. We'll tell you when you do.

When Surgery

When Surgery Is Genuinely Needed

Conservative care has limits. Surgery is genuinely indicated when:

Daily-activity-limiting pain despite 3+ months of proper conservative treatment.
X-ray confirms Grade 3–4 joint space narrowing.
Sleep regularly disturbed by pain.
Walking distance progressively reducing.
Mechanical symptoms (locking, giving way) suggest a structural problem.

If you genuinely meet these criteria, modern knee replacement is excellent — 95% of patients are satisfied at 5 years. Robotic / navigated surgery further improves alignment precision.
