Arthrosamid® is a next-generation injectable treatment for knee osteoarthritis. It is designed to provide long-lasting pain relief and enhanced joint function, particularly for individuals who have not responded well to conventional therapies such as steroid injections, physiotherapy, or oral medications.

The treatment involves a single injection of a hydrogel composed 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 integration helps reduce inflammation, stiffness, and pain, while improving overall joint mobility.

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

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

Arthrosamid® offers a range of benefits that make it an attractive alternative to surgery:

Long-lasting pain relief – Clinical studies show significant pain reduction as early as four weeks post-injection, with benefits maintained at three years
Minimally invasive – The procedure is performed under local anaesthesia and typically takes less than 30 minutes
Outpatient treatment – No hospital stay required; patients can return home the same day.
Safe and well-tolerated – Side effects are generally mild and temporary, such as minor swelling or discomfort at the injection site.
Improved mobility and quality of life – Patients often report better joint function and reduced reliance on pain medications.
Delays or avoids surgery – For many, Arthrosamid® can postpone or even eliminate the need for knee replacement surgery.

Arthrosamid® is administered in a simple, one-step procedure by a qualified Orthopaedic Consultant. The process includes:

Local anaesthetic is applied to numb the area.
The knee is cleaned and prepared for injection.
Using ultrasound guidance, the hydrogel is injected directly into the joint space.
A small dressing is applied, and patients are typically 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 like a shock absorber, reducing friction between bones and cushioning the joint. Over time, this helps to reduce inflammation, relieve pain, and restore mobility.

Clinical trials have shown that Arthrosamid® not only improves symptoms but also maintains these improvements over the long term. In a three-year prospective study, patients experienced sustained reductions in pain and stiffness, with no degradation of the hydrogel.

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

Have 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 appropriate for individuals with active infections, bleeding disorders, or those currently on anticoagulant therapy. Your consultant will assess your medical history to determine if Arthrosamid® is right for you.
