What Does "70–85% Success Rate" Mean?

In published clinical studies, 70–85% of patients treated with mesenchymal stem cell (MSC) therapy for knee osteoarthritis & joint pain experienced statistically significant and clinically meaningful improvements. "Meaningful improvement" is measured using validated clinical scales specific to each condition — not just subjective reports.

It's important to note that success rates vary based on disease severity, patient age, overall health, and treatment protocol. Our clinical team evaluates each patient individually to provide realistic expectations during the consultation phase.

What Improvement Looks Like — Timeline

Expected Improvement Timeline

Most patients notice reduced pain and improved mobility within 4–12 weeks. Cartilage regeneration visible on MRI at 3–6 months. Continued improvement up to 12–18 months.

Factors That Influence Success

Disease Stage

Earlier-stage conditions generally respond better to stem cell therapy. Patients with mild-to-moderate disease typically achieve the best outcomes. Advanced cases may still benefit but with more variable results.

Disease Duration

Patients who seek treatment earlier in their disease course tend to achieve better outcomes. However, meaningful improvements have been documented even in patients with longstanding conditions.

Overall Health

Patients in better overall health — non-smokers, healthy body weight, well-managed comorbidities — tend to have stronger stem cell responses and more durable improvements.

Protocole de traitement

Cell count, delivery method (IV, intrathecal, intra-articular), and use of adjunctive therapies (exosomes, PRP) all influence outcomes. Our protocols are personalized for each patient.

What "Success" Includes

Measurable reduction in primary symptoms (pain, inflammation, disability scores)
Improved quality of life on validated assessment scales
Reduced dependence on medications where applicable
Improved functional capacity and daily activities
Stabilized or improved diagnostic imaging (MRI, echocardiography, etc.)
Patient-reported satisfaction with treatment outcomes

Setting Realistic Expectations

We believe in honest, evidence-based communication. While 70–85% of patients experience meaningful improvement, this also means 30–30% may not respond as strongly. Factors like advanced disease stage, significant comorbidities, or unrealistic expectations can affect perceived outcomes.

During your free consultation, our medical team will review your specific case, discuss realistic expectations based on your condition stage and health profile, and provide an honest assessment of your candidacy.

Questions fréquemment posées

Published meta-analyses of randomized controlled trials report 70–85% of patients experience meaningful improvement in pain, function, and quality of life after MSC therapy for knee osteoarthritis. Results vary based on disease severity, patient age, and overall health.

Clinical studies show improvements lasting 2–5+ years after a single treatment session. Some patients maintain benefits beyond 5 years. Factors affecting durability include activity level, body weight, and whether additional maintenance sessions are undertaken.

Anti-inflammatory effects begin within 2–4 weeks, with most patients noticing reduced pain and improved mobility. Significant cartilage regeneration occurs between 3–6 months, visible on follow-up MRI. Continued improvement is typical up to 12–18 months post-treatment.

Yes, multiple MRI-based studies have demonstrated measurable cartilage regeneration after MSC therapy. A 2024 meta-analysis of 18 RCTs confirmed significant cartilage thickness improvement compared to placebo. The degree of regeneration varies by patient and disease stage.
