Is Arthrosamid a Scam? The Truth About This Knee Injection
✅ Medically reviewed | Updated July 2026
You wake up, swing your legs out of bed, and your knee greets you with that familiar stiff ache. Stairs feel like a negotiation. Long walks feel like a memory. You have tried painkillers, physiotherapy and maybe a steroid injection or two. Each one helped for a while, and then the pain crept back.
Then you hear about a single knee injection that may ease pain for years. It sounds almost too good to be true, and that is exactly why so many people type “is Arthrosamid a scam” into Google before they book anything.
That suspicion is healthy. The private healthcare market has its share of overhyped treatments, vague promises and hidden fees. You deserve straight answers before you spend thousands of pounds on your knee.
This guide gives you those answers. It covers what Arthrosamid is, how it works, what the published evidence shows and where the evidence still falls short. It also covers what the treatment costs in the UK and who should avoid it. By the end, you can judge the treatment on facts, not fear or hype.
Is Arthrosamid a Scam? The Short Answer
No. Arthrosamid is a real, clinically studied treatment for knee osteoarthritis. Contura, the manufacturer, supports it with peer-reviewed research, and regulated clinics across the UK offer it.
It is not a miracle cure. It does not reverse joint damage, and it does not work for everyone. The honest answer to “is Arthrosamid a scam” is this: the treatment is legitimate, but your results depend on choosing the right clinic and being the right candidate.
What Is Arthrosamid Injection?
Arthrosamid is a non-biodegradable hydrogel. It contains 97.5% water and 2.5% cross-linked polyacrylamide. A clinician injects it directly into the knee joint under ultrasound guidance.
Unlike steroid or hyaluronic acid injections, Arthrosamid does not simply coat or lubricate the joint for a short time. It aims to integrate with the synovial tissue that lines the inside of your knee.
A Single Treatment, Not a Course
Most patients need only one injection. There is no general anaesthetic and no incision. The whole procedure takes around 30 to 45 minutes, and most people go home the same day.
How Arthrosamid Works
Arthrosamid works in four stages.
Stage 1: Injection. After a local anaesthetic, the clinician places the hydrogel into the synovial cavity of the knee using ultrasound to guide the needle.
Stage 2: Uptake. The hydrogel spreads through the synovial fluid. The joint’s natural filtering process then draws it into the synovial membrane. Official Arthrosamid materials say this integration is largely complete within four to six weeks.
Stage 3: Integration. Once the hydrogel sits within the tissue, official materials describe increased elasticity and resilience in the joint lining.
Stage 4: Lasting support. Your body does not break down Arthrosamid the way it breaks down other injected materials. That is why published follow-up studies report improvements lasting up to five years after one injection.

The Science Behind Arthrosamid Injection
The science centres on the synovial membrane. This soft lining often becomes inflamed in knee osteoarthritis, a condition called synovitis. Many patients never realise this lining may play a part in their pain.
Clinic materials state that the hydrogel may help reduce inflammatory activity in the synovial lining while creating a cushioning effect. Researchers are still studying the exact pathways behind the pain relief.
What the Research Actually Shows
Two pieces of evidence stand out:
- A randomised controlled trial compared Arthrosamid with hyaluronic acid. It found Arthrosamid was non-inferior over 12 months after a single injection, with meaningful improvements in pain and function.
- A 2025 five-year follow-up study reported sustained improvements in pain, stiffness and function in study participants through to five years. It reported no serious events linked to the device.
According to official Arthrosamid messaging from January 2026, doctors have treated more than 20,000 patients.
Where the Evidence Falls Short
Here is something most brand websites skip. The evidence base keeps growing, but it remains relatively limited compared with more established treatments. Studies involve selected patients in controlled settings, so your personal result may differ. A trustworthy clinic tells you this upfront rather than hiding it.
What Arthrosamid Injection Treats
Doctors use Arthrosamid to manage the symptoms of knee osteoarthritis. It may help with:
- Persistent knee pain that rest, medication or physiotherapy has not fixed
- Morning stiffness or stiffness after sitting
- Difficulty with stairs, standing up from a chair or walking far
- Mild to moderate swelling around the knee
- Pain when bending or straightening the leg
- Lost confidence in everyday movement
Not all knee pain comes from osteoarthritis, though. A proper clinical assessment confirms the cause before any treatment starts.
Who Should Avoid It
Arthrosamid may not suit you if you have:
- A known allergy to polyacrylamide
- An active infection in or around the knee
- Recent knee surgery
- Severe structural joint damage
- Knee pain from a different condition
Arthrosamid Injection vs Other Knee Injections
Many patients compare several options before deciding. Here is how the clinic’s published comparison stacks up:
| Treatment | How Long It Lasts | Injections Needed |
| Arthrosamid | Up to 5 years in follow-up studies | Single injection |
| Steroid | Around 2–10 weeks (NICE) | Repeated as needed |
| Hyaluronic acid | Months, varies (NICE does not recommend it for osteoarthritis) | 1–3 typically |
| PRP | Variable, and NICE notes limited evidence quality | 1–3 sessions |
| Knee replacement | 15–20 years typically | Surgery required |
Arthrosamid sits in the gap between repeated short-term injections and major surgery. For some suitable patients, it may help them postpone more invasive options, although no clinic can guarantee that.
Arthrosamid Injection Cost UK: What You Really Pay
Price is a major reason people ask whether Arthrosamid is a scam. Unclear pricing breeds distrust. So here are the exact figures that Dr SNA Clinic publishes.
Arthrosamid Injection Cost for One Knee
- £2,800 (previously £3,200)
- Includes enhanced recovery support with post-injection physio guidance and supplement advice
Cost for Both Knees
- £5,300 (previously £6,400)
- Available for suitable patients with symptoms in both knees, after assessment and imaging review
What Every Package Includes
- A full consultation with Dr Abbas
- The ultrasound-guided injection
- A follow-up assessment and ongoing support
The consultation fee is £100, and the clinic deducts it from your treatment cost if you go ahead. The clinic also offers 0% finance to spread payments. The clinic lists no hidden fees, and you carry no obligation to proceed after your consultation.
Practical Tip: Compare Value, Not Just Price
When you compare the Arthrosamid injection cost with repeated steroid or hyaluronic acid injections, count the number of appointments, the recovery days and how long each option may last. A single injection with long follow-up data can offer different value from a cheaper treatment you repeat several times a year.

Recovery and Results Timeline
Week 1–2: Your knee settles. Mild discomfort, swelling or fullness is normal. Avoid strenuous activity.
Week 4: Some patients notice early changes in comfort or stiffness.
Weeks 8–12: Many patients report their biggest improvements during this window. Your follow-up review usually falls here.
12 months and beyond: Studies report sustained benefits for up to five years in study participants.
Plan for around 3–5 days of reduced activity. Your doctor may also recommend physiotherapy to get the most from the treatment.
Side Effects to Know
Common, short-lived effects include pain at the injection site, swelling, temporary stiffness and minor bruising. Infection is rare but serious.
