Is stem cell therapy legal in the UK?

Yes, but regulated. The Human Tissue Authority (HTA) licences clinics to process and inject autologous (your own) stem cells. Allogeneic (donor) stem cells are not approved for most orthopedic conditions. Any clinic offering 'young donor cells' for joints is operating outside UK regulations. Always verify HTA licensure.

Does stem cell therapy hurt?

Adipose harvest feels like mild liposuction under local anesthetic—pressure and tugging, not sharp pain. The injection itself is a needle stick, similar to any joint injection. Most patients rate discomfort as 3-4/10. Post-procedure soreness (like a bruise) lasts 2-3 days. Overall, far less invasive than surgery.

When will I see results?

Timeline: Weeks 1-2 (stem cells migrate and release healing factors), Weeks 3-6 (inflammation decreases, pain reduces), Weeks 6-12 (new tissue forms, mobility improves), Months 3-6 (significant functional gains), Months 6-12 (peak results as tissue fully remodels). Don't expect instant relief—regeneration takes time.

How long do results last?

Highly variable. Orthopedic studies show: 60-70% of knee OA patients maintain improvement at 24 months. Tendon injuries: 12-18 months typical, some report 3+ years. Factors affecting duration: severity of initial damage, lifestyle (weight, activity), age, metabolic health. Some patients need retreatment; others experience permanent improvement.

Can stem cells regrow cartilage?

Yes, but with caveats. MSCs can stimulate cartilage regeneration in early-to-moderate osteoarthritis (grades 2-3) where some cartilage remains. They won't rebuild bone-on-bone joints (grade 4 OA)—that requires surgery. MRI or X-ray imaging determines if you have enough viable tissue. Realistic expectation: improved cushioning and pain reduction, not full cartilage restoration.

What's the difference between stem cells and PRP?

PRP (platelet-rich plasma) uses growth factors from your blood to stimulate healing. Stem cells are actual regenerative cells that can become new tissue. PRP is cheaper (£500 vs. £6,000), less invasive (blood draw vs. fat extraction), but less potent. For mild conditions, try PRP first. For moderate-to-severe degeneration, stem cells offer more robust regeneration.

Are there any side effects?

Common: injection site soreness (2-3 days), temporary swelling, mild bruising from adipose harvest. Rare: infection (<1%, same as any injection), allergic reaction (extremely rare with autologous cells), no improvement (20-35% non-responders). Serious complications are very rare when performed by qualified physicians under sterile conditions.

Can I combine stem cells with other treatments?

Yes. Many patients combine stem cells with: PRP boosters (6-12 weeks post-stem cell treatment), physiotherapy protocols (essential for optimal outcomes), hyaluronic acid injections (for additional joint lubrication), shockwave therapy (for associated tendon issues). Avoid: NSAIDs immediately post-injection (they inhibit inflammation needed for healing).

Will insurance cover stem cell therapy?

Unlikely. Most UK private insurers exclude stem cell therapy as 'experimental' or 'investigational' except for specific cancer treatments. Exceptions exist if prescribed by consultant orthopedic surgeon with documented imaging. Always pre-authorize with your insurer. We provide detailed invoices for self-submission, but don't guarantee reimbursement.

How do I know if I'm a good candidate?

Ideal candidates: moderate osteoarthritis (grades 2-3), partial tendon tears, chronic tendinopathy not responding to conservative care, age 30-70, healthy weight, non-smoker. Poor candidates: severe bone-on-bone arthritis, active infection, uncontrolled diabetes, blood clotting disorders, unrealistic expectations. Book a consultation with imaging (MRI/X-ray) for assessment.

How is Arthrosamid different from gel injections I've had before?

You've likely had hyaluronic acid (Synvisc, Ostenil, Durolane). That's temporary viscosupplementation—your body absorbs it in 6-12 months. Arthrosamid is non-biodegradable hydrogel that stays in your joint permanently, integrating into tissue. It's a fundamentally different material and mechanism, which is why it lasts years, not months.

Does the injection hurt?

Comparable to any knee injection—brief needle stick, pressure sensation as gel enters joint, mild discomfort. We use local anesthetic. Most patients rate pain as 3-4/10 for 5-10 seconds during injection. Post-procedure soreness (like a bruise) lasts 24-48 hours. Far less painful than surgery, far more tolerable than chronic knee pain.

How quickly will I notice improvement?

Timeline: Week 1 (swelling settles), Week 2 (first pain reduction), Weeks 4-6 (significant mobility gains), Weeks 8-12 (near-maximal benefit). Some patients notice immediate relief as the gel supports bone-on-bone grinding. Others take 6-8 weeks as inflammation calms and hydrogel fully integrates. Patience is key.

Will I need repeat injections?

No. Arthrosamid is designed as a single-treatment solution. Clinical trial data shows sustained benefit through 156 weeks (3 years) without retreatment. Some patients report ongoing improvement beyond trial endpoints (5+ years). If pain returns, it's usually disease progression requiring re-assessment—not Arthrosamid failure requiring re-injection.

Can Arthrosamid delay or prevent knee replacement?

Possibly. Many orthopedic surgeons use Arthrosamid to 'buy time' for patients not yet ready for replacement—whether due to age, activity level, or personal preference. If it delivers 3-5 years of acceptable function, that's 3-5 more years of your natural knee. No guarantee it prevents surgery, but it's a reasonable interim strategy.

What are the risks and side effects?

Common: temporary swelling (15-20% of patients, resolves in 2-5 days), mild pain at injection site, stiffness for 24-48 hours. Rare: infection (<1%, same as any injection), allergic reaction (extremely rare—polyacrylamide is biocompatible), no improvement (20-30% non-responders). Serious complications are exceptionally rare in published literature.

Can I combine Arthrosamid with other treatments?

Yes. Common combinations: PRP injections 3-6 months post-Arthrosamid (boosting tissue repair), physiotherapy focusing on quadriceps strengthening (essential for knee stability), weight management programs (reduces joint load), bracing for malalignment (offloads affected compartment). Avoid: steroids immediately before/after (may interfere with tissue integration).

Is Arthrosamid FDA-approved?

Arthrosamid has CE Mark approval in Europe (including UK), meaning it meets EU medical device safety standards. It's not yet FDA-approved in the US, which is why it's only available in EU/UK clinics currently. Clinical trials are ongoing in the US. CE Mark is the equivalent European regulatory approval.

What happens if I eventually need knee replacement?

Arthrosamid doesn't complicate future surgery. It integrates into synovial tissue, not bone or cartilage. Orthopedic surgeons simply remove it during joint replacement (it's visible and easy to excise). Multiple EU studies confirm no increased surgical difficulty or complications when replacing knees previously treated with Arthrosamid.

How do I know if I'm a good candidate?

Ideal profile: age 45-75, mild-to-moderate knee OA (grades 2-3), mechanical pain (worse with activity, better with rest), failed conservative care, not yet severe enough for replacement, realistic expectations. Book consultation with recent imaging (X-ray or MRI within 6 months) for assessment. We'll tell you honestly if you're suitable.

How does shockwave compare to Viagra or Cialis?

PDE5 inhibitors like Viagra/Cialis temporarily increase blood flow for 4-36 hours by relaxing smooth muscle. They don't fix underlying vascular damage. Shockwave therapy stimulates new blood vessel growth (angiogenesis), addressing the root cause. About 57% of men achieve natural erections without pills after completing treatment, and many others reduce medication dosage. Think of pills as symptom management; shockwave as vascular repair.

Is shockwave therapy painful?

No. Most patients describe a rhythmic tapping sensation—similar to light percussion massage. Energy levels are adjustable, and we can pause anytime. Pain scores average 1/10. No anesthesia or numbing required, though some clinics apply numbing cream for extra comfort.

When will I see results?

Many men notice stronger morning erections by week 2-3 (sessions 4-6). Peak results appear 8-12 weeks post-treatment as new blood vessels fully mature. Spontaneous erections, improved rigidity, and reduced medication dependence develop gradually—not overnight.

How long do results last?

Clinical studies show 18-24 months on average, with some men maintaining improvements for 3+ years. Longevity depends on age, diabetes control, cardiovascular health, and lifestyle (smoking, exercise, diet). Annual booster sessions (3-6 treatments) help sustain vascular health.

Can I use shockwave if I have diabetes or heart disease?

Usually yes, if your cardiologist has cleared you for sexual activity. Shockwave doesn't stress the cardiovascular system. Diabetics may need the 12-session protocol for optimal vascular repair. We coordinate with your GP or endocrinologist to optimize glucose control during treatment.

What's the success rate for shockwave therapy?

Published studies report 76-84% clinical effectiveness for mild-to-moderate vascular ED. About 57% achieve medication-free erections, and many others see significant improvements in rigidity, spontaneity, and IIEF scores. Success depends on baseline vascular health, ED severity, and protocol adherence.

Should I combine shockwave with the P-Shot®?

For maximum regeneration, yes. The consensus protocol is 6 shockwave sessions first, then P-Shot® 1-2 weeks later. Shockwave primes tissue and creates micro-channels for better PRP absorption. Combined outcomes are 30-40% better than either therapy alone.

Will insurance cover shockwave therapy for ED?

Unlikely in the UK. Most insurers consider it elective/investigational for erectile dysfunction. Some policies cover shockwave for Peyronie's disease or post-prostatectomy rehab under medical necessity codes. We provide itemised invoices for you to submit. Check your specific plan before treatment.

How is focused shockwave different from GAINSWave?

GAINSWave is a branded marketing term for low-intensity shockwave therapy. At Dr. SNA Clinic, we use FDA-listed focused shockwave devices (not radial spa machines) with Doppler-guided treatment mapping. Our protocols follow European Association of Urology guidelines—not franchise templates. The technology is the same category (LI-ESWT), but our approach is physician-led with objective outcome tracking.

Can younger men benefit from shockwave therapy?

Absolutely. Men in their 30s-40s with vascular ED (often from diabetes, metabolic syndrome, or cycling injuries) respond excellently. Early intervention prevents progression and establishes healthy vascular patterns before damage becomes extensive. Younger tissue also regenerates faster.

How long should I try lifestyle tweaks before PRP?

Give any at-home plan 12 weeks while you normalise labs. If shedding persists, schedule a trichology-led consultation so we can combine diagnostics with PRP or exosomes.

Can I stay on minoxidil or finasteride?

Yes. We often keep patients on their prescription or topical plan, but we adjust dosages after lab review to minimise side effects.

What does maintenance look like?

Most patients book a single PRP booster every 6–9 months plus LED sessions during seasonal shedding.

Who is an ideal candidate for London stem cell therapy?

Patients struggling with chronic knee, hip, or shoulder pain, recurring sports injuries, or inflammatory arthritis gain the most. We also evaluate skin and longevity concerns when cosmetic applications or systemic wellness support is the priority.

How much should I budget?

Expect £2,000–£6,000 for single-joint sessions, £4,000–£10,000 for advanced regenerative cell therapy, and from £1,500 for cosmetic stem cell boosters—mirroring the guide’s cost ranges.

Is there downtime or special prep?

Procedures are outpatient with <48 hours of downtime. You’ll have a consultation, imaging review, harvesting, and reinjection on the same day in most cases, plus bespoke post-care instructions.

Can I combine counselling with medical treatments?

Absolutely. We collaborate with sex therapists so behavioural rewiring and regenerative medicine reinforce each other.

How soon will I see results after shockwave therapy?

Most patients notice fuller morning erections by session four, with peak results 8–12 weeks after completing the series.

Is the P-Shot painful?

We use numbing cream plus vibration analgesia. Patients report minimal discomfort and can resume daily activities immediately.

Do I need genetic testing before booking treatments?

Not always. We can infer risk factors from family history and biomarkers, but we do offer nutrigenomic panels if you want personalised longevity protocols.

How soon will a PRP facelift show results?

Glow improves within 2–3 weeks, with maximal collagen remodelling at 3 months. Results last 12–18 months when paired with sleep, nutrition, and SPF.

Can I combine PN boosters with dermal fillers?

Yes. Polynucleotides prep the skin so filler integration looks seamless. We often stage PN first, then refined filler placement two weeks later.
