How Much Does Arthrosamid Cost in the UK? Prices Explained

Prices correct as of July 2026.

Arthrosamid is one of the most talked-about treatments for knee osteoarthritis in the UK — a single injection of a non-degradable hydrogel that cushions the joint from within and provides long-lasting pain relief. One of the first questions patients ask is a simple one: how much does it cost? This guide explains typical UK prices, what is (and is not) included, and how to compare quotes sensibly.

The quick answer

Across the UK, an Arthrosamid injection for one knee typically costs between £2,000 and £3,500. In London, prices at private hospitals commonly sit at the upper end of that range — often £3,000 or more per knee once consultation and imaging fees are added.

At Joint Care London, Arthrosamid costs £2,995 for one knee or £4,995 for both knees, with an initial consultation including diagnostic ultrasound at £405. Full details are on our fees page.

What determines the price?

Quotes for Arthrosamid vary more than for most injections. When comparing clinics, check what the headline price actually includes:

• The consultation and diagnosis. A proper assessment — including ultrasound or a review of recent imaging — is essential to confirm you are a suitable candidate. Some clinics bundle this into the price; many charge it separately.
• Ultrasound guidance during the injection. Accurate intra-articular placement matters for results. At Joint Care London every Arthrosamid injection is performed under ultrasound guidance by a consultant, included in the price.
• The setting. Private hospital theatres carry higher facility fees than specialist outpatient clinics, which is one reason hospital-based quotes are often £3,000–£3,500 or more. Arthrosamid is a day-case outpatient procedure and does not require a hospital theatre.
• Follow-up. Ask whether review appointments are included if you need them.

Is it worth the cost?

Compared with other injectable treatments, Arthrosamid has a higher upfront cost but a fundamentally different profile: it is a single, non-degradable implant rather than a temporary treatment. Steroid injections (£525) typically provide weeks to a few months of relief and are usually limited to a few repeats per year; hyaluronic acid (£625) often lasts several months to a year. Clinical follow-up data for Arthrosamid show sustained improvement beyond three years for many patients — so for people who would otherwise need repeated injections year after year, the economics can work out favourably, quite apart from the convenience of a single procedure.

It is also considerably cheaper than the private cost of a knee replacement (typically £13,000–£17,000), which is why many patients use Arthrosamid to manage symptoms and delay surgery.

Is Arthrosamid available on the NHS?

Not routinely. Arthrosamid is currently a private treatment in the UK, which is why understanding the pricing landscape matters.

Will my health insurance pay for it?

Coverage varies by insurer. Some treat Arthrosamid as a newer technology and do not yet cover it; others assess claims case by case. If you hope to claim, contact your insurer before booking — we are happy to provide any clinical documentation they require.

Frequently asked questions

How much does Arthrosamid cost in the UK?

Typically £2,000–£3,500 per knee depending on the clinic and what is included. At Joint Care London: £2,995 for one knee, £4,995 for both.

Is Arthrosamid cheaper outside London?

Sometimes, though not always — the biggest price differences come from the setting (hospital vs specialist clinic) and what is bundled, rather than geography alone. Always compare like for like.

How long does Arthrosamid last?

The hydrogel is non-degradable and clinical follow-up data show sustained benefit beyond three years for many patients. It is designed as a single, long-lasting treatment rather than a repeated injection.

Can I have Arthrosamid in both knees at once?

Yes — treating both knees in a single visit is common, and costs £4,995 at Joint Care London.
