Is Arthrosamid Suitable for Patients With Both Knees Affected?

✅ Medically reviewed | Updated July 2026

If both your knees ache, you’ve probably noticed the advice online rarely does. Most guides to Arthrosamid Injection quietly assume you’re only dealing with one troublesome joint — but osteoarthritis doesn’t read the script, and plenty of people are managing pain, stiffness, and stubborn stiffness in both knees at once. So the question worth answering properly is this: can a single treatment approach realistically cover both joints, or are you looking at two procedures, two recoveries, and twice the decision-making?

This guide answers it in full. It covers how Arthrosamid actually works inside the joint, what changes clinically when both knees need attention, current London pricing, and how Mr Syed Nadeem Abbas at Dr SNA Clinic assesses each knee on its own merits before recommending anything — no assumptions, no one-size-fits-all answers.

What Is Arthrosamid Injection?

Arthrosamid Injection is a non-surgical treatment for suitable patients with knee osteoarthritis. Doctors describe it as a non-biodegradable hydrogel made from 97.5% water and 2.5% cross-linked polyacrylamide. Clinicians inject it directly into the knee joint under ultrasound guidance, and the hydrogel then integrates with the synovial membrane rather than simply lubricating the joint for a few weeks.

This is the detail most patients miss: Arthrosamid does not wash out of the joint the way steroids or hyaluronic acid do. Because it is non-biodegradable, the body does not gradually break it down. Mr S N Abbas performs every Arthrosamid Injection personally at the Wimpole Street clinic, reviewing imaging, medical history, and symptoms before confirming whether a patient is suitable.

How Arthrosamid Works

Arthrosamid works differently from short-term knee injections. Doctors inject the hydrogel into the synovial cavity after applying local anaesthetic, and the joint’s own filtering process gradually draws it into the synovial membrane. Manufacturers describe this uptake as largely complete within four to six weeks.

As the hydrogel settles into the tissue, it may support elasticity and resilience within the joint lining. Because the material stays in place rather than breaking down, published follow-up studies have reported sustained pain and function improvements for up to five years after a single injection in study participants, though individual outcomes vary from person to person.

The Science Behind Arthrosamid Injection

The science centres on the synovial membrane — the soft tissue lining inside the knee. Once injected, the hydrogel integrates into this lining instead of coating the joint surface temporarily. Clinical materials describe this as a gradual physical and biological process, not an instant fix.

A randomised controlled trial found Arthrosamid to be non-inferior to hyaluronic acid over 12 months, with clinically meaningful improvements in pain and function reported in the Arthrosamid group. A separate 2025 publication tracking patients for five years found sustained improvements in pain, stiffness, function, and overall patient assessment. Reported safety data showed mostly procedure-related effects, such as short-term swelling, with no serious device-related events recorded in the five-year extension study.

What Arthrosamid Injection Treats

Arthrosamid Injection treats the symptoms of knee osteoarthritis. It does not cure arthritis or reverse existing joint damage. For suitable patients, it may ease the following:

• Persistent aching pain that continues despite rest or physiotherapy
• Morning stiffness or stiffness after long periods of sitting
• Reduced range of movement when bending or straightening the knee
• Mild to moderate swelling around the joint
• Loss of confidence in walking, climbing stairs, or standing up from a chair

Not every knee pain traces back to osteoarthritis, so Mr Abbas examines each patient individually rather than assuming the cause.

Can Arthrosamid Treat Symptoms Affecting Each Knee?

This is where most competitor content stays vague. Dr SNA Clinic’s own treatment information confirms that Arthrosamid Injection may be considered for suitable patients with symptoms affecting both knees, following proper assessment and imaging review. In practice, this means Mr Abbas assesses each knee on its own clinical merits — one knee is never treated simply because the other one qualifies.

Why Assessment Matters More When Two Joints Are Involved

Osteoarthritis rarely progresses identically in both knees. One joint might show mild wear while the other has more advanced changes. Mr Abbas reviews symptoms, history, and imaging for each knee separately during consultation, then explains honestly whether treating one, both, or neither joint is the sensible next step. He will say so plainly if Arthrosamid is not the right option for a particular knee, even if it suits the other.

Why Choose Arthrosamid Injection

Patients weighing their options often compare Arthrosamid against steroid injections, hyaluronic acid, PRP, or knee replacement surgery. A few points set it apart:

• A single injection, rather than a repeated course of appointments
• Study follow-up data extending to five years, unlike the weeks-long relief typical of steroids
• An outpatient procedure under local anaesthetic, with no general anaesthetic required
• Same-day discharge for most patients, without an overnight hospital stay

NICE guidance currently advises against offering hyaluronan injections for osteoarthritis, which is one reason many patients now ask about Arthrosamid instead. That said, Arthrosamid will not suit everyone, and it does not guarantee results — Mr Abbas discusses realistic expectations at consultation rather than overselling the treatment.

Arthrosamid Injection Cost in London

Transparent pricing removes a lot of the guesswork before booking. According to Dr SNA Clinic’s published pricing:

• Single knee treatment: £2,800 (reduced from £3,200), including enhanced recovery support
• Treatment for both knees: £5,300 (reduced from £6,400), including enhanced recovery support for each joint
• Consultation fee: £100, which is redeemable against treatment cost if you go ahead
• 0% finance is available for patients who want to spread the cost

Every package includes a comprehensive consultation with Mr S N Abbas, the ultrasound-guided injection itself, and a follow-up assessment. Patients researching arthrosamid injection cost UK often compare this against repeated hyaluronic acid courses or the long-term cost of delaying knee replacement — and a single-injection model tends to work out more predictable over several years, even though upfront pricing looks higher than one steroid shot.

What the Price Includes

There are no hidden add-ons at Dr SNA Clinic. The quoted arthrosamid injection cost covers the procedure, the ultrasound guidance, physio guidance afterwards, and a scheduled review. Prices are confirmed at consultation and are correct at the time of publication, so it’s worth confirming current figures before booking.

What Happens at Your Consultation

The consultation is not a sales pitch. Mr Abbas takes a full history of your symptoms, reviews any available imaging, and explains what outcomes are realistic for your specific knees. NICE guidance notes that osteoarthritis is usually diagnosed clinically, without necessarily requiring imaging, though Mr Abbas arranges scans where clinically appropriate.

Patients leave the consultation with a clear answer — whether Arthrosamid suits one knee, both knees, or neither — and there is no obligation to proceed on the day.

Recovery After Treatment

Most patients go home the same day. Mild discomfort, swelling, or a feeling of fullness in the treated knee or knees is normal during the first few days and is not a sign that treatment has failed. Mr Abbas advises against strenuous activity in the short term and may recommend physiotherapy to support recovery. Noticeable improvements typically build over four to twelve weeks, as the hydrogel integrates with the joint lining, rather than appearing overnight.

Finding an Arthrosamid Injection Near You

Searches for “arthrosamid injection near me” usually lead patients to providers offering only generic information. At Dr SNA Clinic, every Arthrosamid Injection is performed personally by Mr Syed Nadeem Abbas, MBBS, MRCSEd, MSc (Distinction) — a former NHS trauma and orthopaedic specialist with formal Arthrosamid certification through the American Cellular Medical Association. He does not delegate the procedure to junior staff.

The clinic sits at 48 Wimpole Street, Marylebone, London W1G 8SF, and opens from 10:00 to 18:00, UK time. You can reach the team on +44 7955 836986 or +44 20 3846 7111, or book directly through the clinic’s online consultation booking page. Patients travel from across the UK and internationally specifically to see Mr Abbas rather than settle for a clinic offering the injection without his level of specialist training.

Frequently Asked Questions

Is Arthrosamid safe for patients needing treatment in more than one knee?
Each knee is assessed individually. Treatment for both joints may be considered for suitable patients, but Mr. Abbas confirms suitability separately for each knee before proceeding.

Does treating both knees cost double the single-knee price?
No. Dr SNA Clinic prices treatment for both knees at £5,300, which is less than double the single-knee price of £2,800.

How soon will I notice a difference?
Most patients report the clearest improvements between four and twelve weeks after injection, as the hydrogel integrates with the synovial tissue.

Can I combine Arthrosamid with other treatments?
Physiotherapy is often recommended alongside Arthrosamid to support recovery. Patients interested in regenerative options for other concerns, including men’s health treatments such as the P-Shot, can explore Dr SNA Clinic’s full regenerative treatment range during their visit.

Where can I learn more about how the treatment works before booking?
Mr Abbas has recorded a series of short explainer videos covering knee osteoarthritis and Arthrosamid’s mechanism, available on the Dr SNA Clinic YouTube channel.

Final Thought

Living with pain in both knees can feel like managing two separate problems at once — but it doesn’t have to mean two separate treatment journeys. With proper assessment, Arthrosamid Injection may offer suitable patients a single, focused path forward for each affected joint. The only way to know for certain is a proper consultation with Mr Abbas, where imaging, history, and honest clinical judgement — not assumptions — decide what’s right for you.
