Arthrosamid® is a next-generation injectable treatment for knee osteoarthritis, designed to offer long-lasting pain relief and improved joint function. It’s especially beneficial for individuals who haven’t responded well to conventional treatments such as steroid injections, physiotherapy, or oral medications.

The procedure involves a single injection of a hydrogel made up of 97.5% water and 2.5% cross-linked polyacrylamide. Once injected into the knee joint, Arthrosamid® cushions the joint and integrates with the synovial membrane - the soft tissue lining the joint capsule. This helps reduce inflammation, stiffness, and pain, while enhancing mobility.

Unlike traditional visco-supplement injections, Arthrosamid® becomes part of the joint lining, offering sustained relief that can last up to three years or more.

It’s particularly effective for advanced osteoarthritis, including cases where cartilage has significantly worn down - commonly referred to as “bone-on-bone” arthritis.

Arthrosamid® offers a range of benefits that make it a compelling non-surgical option for managing knee osteoarthritis:

• Long-lasting pain relief – Clinical studies show significant improvement as early as four weeks after injection, with effects lasting up to three years.
• Minimally invasive – The procedure is carried out under local anaesthesia and typically takes less than 30 minutes.
• Outpatient treatment – No hospital stay required; patients can go home the same day.
• Safe and well-tolerated – Most side effects are mild and temporary, such as slight swelling or discomfort at the injection site.
• Improved mobility and quality of life – Many patients report better joint function and reduced reliance on pain medication.
• Delays or avoids surgery – For some, Arthrosamid® can postpone or even eliminate the need for knee replacement surgery.

Arthrosamid® is administered through a straightforward, one-step procedure by a qualified orthopaedic consultant at Syon Clinic. The process includes:

1. Application of a local anaesthetic to numb the area
2. Cleaning and preparation of the knee for injection
3. Ultrasound-guided injection of the hydrogel directly into the joint space
4. A small dressing is applied, and patients are usually able to walk out shortly after

Once inside the joint, the hydrogel integrates with the synovial lining, enhancing the viscosity of the synovial fluid. This acts as a shock absorber, reducing friction between bones and cushioning the joint. Over time, it helps relieve pain, reduce inflammation, and improve mobility.

Clinical studies have shown that Arthrosamid® not only delivers symptom relief but also maintains these benefits long-term. In a three-year prospective study, patients experienced sustained reductions in pain and stiffness, with no breakdown of the hydrogel.

Arthrosamid® is suitable for most adults living with knee osteoarthritis, especially those who:

• Experience moderate to severe symptoms
• Have not responded to other non-surgical treatments
• Are not ready or eligible for knee replacement surgery
• Prefer a minimally invasive option with long-term benefits

However, it may not be suitable for individuals with active infections, bleeding disorders, or those currently taking anticoagulant medication. Your consultant at Syon Clinic will carefully review your medical history to determine if Arthrosamid® is the right option for you.

At Syon Clinic, Arthrosamid® is available on a self-pay basis, with prices starting from £3,200. This includes the injection and associated care. An initial consultation with one of our specialist orthopaedic consultants is required to assess your suitability for the treatment.
