What is Arthrosamid® and how does it work?

Arthrosamid® is an innovative, non-biodegradable polyacrylamide treatment that's injected directly into your knee joint. It integrates with the synovial tissue, acting as a support that reduces friction and inflammation. Unlike hyaluronic acid injections that break down over months, Arthrosamid® provides sustained relief for up to 5+ years.

Am I a suitable candidate for Arthrosamid® treatment?

Arthrosamid® is ideal for patients with mild to moderate knee osteoarthritis who haven't responded well to conservative treatments like physiotherapy or steroid injections. During your consultation, Mr S N Abbas will assess your condition, review imaging, and determine if Arthrosamid® is the right option for you.

Is the procedure painful?

The procedure is performed under local anaesthesia, so you shouldn't feel significant pain during the injection. Some patients experience mild discomfort or pressure. Any post-procedure soreness is typically minimal and resolves within a few days.

How long does the procedure take?

The actual injection takes about 15 minutes. Including preparation and ultrasound guidance setup, your total appointment time is approximately 30-45 minutes. You can walk out of the clinic the same day.

When will I feel the results?

Many patients notice some improvement within 24-48 hours. However, the full benefits typically develop over 4-12 weeks as the solution fully integrates with your joint tissue. Clinical studies show sustained pain relief for 5+ years post-treatment.

Are there any side effects or risks?

Arthrosamid® has an excellent safety profile with over 20,000 patients treated globally. Common side effects include temporary swelling, stiffness, or mild pain at the injection site, which typically resolves within a few days. Serious complications are rare.

How much does Arthrosamid® treatment cost?

Treatment costs vary depending on individual circumstances. During your free consultation, we'll provide a detailed quote. DrSNA Clinic offers flexible payment options to make this life-changing treatment accessible.

Can I have Arthrosamid® in both knees?

Yes, many patients receive treatment in both knees. Depending on your situation, this can be done in the same session or staged across two appointments. Mr S N Abbas will recommend the best approach for your needs.

Arthrosamid Injection London: What Patients Need to Know

13 February 2026

4 min read

Margaret, a 68‑year‑old grandmother from London, used to enjoy playing with her grandchildren in the park. But over time, her knees became stiff and painful. Even short walks left her exhausted. Painkillers dulled the ache but never solved it, and she worried that surgery might be her only option. Then she heard about Arthrosamid Injection, a non‑surgical treatment available in London that promised long‑lasting relief.

Her story reflects the reality for millions. According to the Office for Health Improvement and Disparities, around 20% of adults in England report a long‑term musculoskeletal problem, with knee osteoarthritis being one of the most common causes. Research shows knee pain increases the risk of depression, falls, and reduced mobility, making effective treatments vital.

The Burden of Knee Pain in the UK

Knee pain is not just a physical issue; it affects every aspect of life.

Prevalence: Osteoarthritis is the most common joint disease, affecting over 8.5 million people in the UK. Knee osteoarthritis accounts for a large proportion of these cases.
Impact on daily life: Patients often struggle with simple tasks such as climbing stairs, walking to the shops, or even standing for long periods.
Emotional toll: Studies show that chronic knee pain doubles the risk of depression and anxiety.
Economic cost: Musculoskeletal conditions are responsible for almost 30 million lost workdays annually in the UK, costing billions in healthcare and productivity.

This scale of suffering highlights why innovative treatments like Arthrosamid Injection are so important.

What Is Arthrosamid Injection?

Arthrosamid is a polyacrylamide hydrogel injection designed for patients with knee osteoarthritis. Unlike steroid or hyaluronic acid injections, Arthrosamid integrates into the joint lining, providing cushioning and reducing inflammation.

How it works:

A single injection delivers the hydrogel directly into the knee joint.
The gel bonds with the synovial tissue, creating a permanent cushion.
This reduces friction, inflammation, and pain, while improving mobility.

Clinical evidence:

A randomised controlled trial showed sustained pain relief for up to 3 years.
A prospective study confirmed 4‑year benefits compared with hyaluronic acid.
New data presented in 2025 demonstrated 5‑year efficacy and 10‑year safety, making Arthrosamid one of the most durable injection options available.

Arthrosamid Injection Cost UK

Private clinics in London typically charge between £2,000 and £3,500 per knee for Arthrosamid Injection. Costs vary depending on:

Clinic reputation and location
Whether imaging (MRI/ultrasound) is included
Follow‑up consultations and aftercare packages

At Knee Pain Clinic UK, patients receive transparent pricing, with consultations and aftercare included to ensure confidence in the treatment journey.

Why cost matters:
While the upfront cost may seem high, many patients consider it worthwhile compared to repeated steroid injections, physiotherapy, or eventual surgery. Arthrosamid’s long‑lasting relief means fewer repeat treatments, making it cost‑effective in the long run.

Benefits for Patients

Patients who choose Arthrosamid Injection often report:

Non‑surgical relief: No incisions, no hospital stay.
Long‑lasting results: Evidence supports benefits lasting up to 5 years.
Improved mobility: Patients often return to daily activities quickly.
Reduced reliance on painkillers: Many report cutting down on medication.
Low risk: Because Arthrosamid is non‑biodegradable, it remains in the joint, avoiding frequent repeat treatments.

For patients like Margaret, this means regaining independence, confidence, and quality of life.
