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:

At Runnymede Hospital, Arthrosamid® is administered in a simple, one-step procedure by qualified Consultant Orthopaedic Surgeons, Mr Joshua Jacob, Mr Paul Trikha, or Mr Ashwin Unnithan.

The process includes:

1. The patient is required to take oral antibiotics one hour prior to treatment.
2. Local anaesthetic is applied to numb the area around the knee.
3. The knee is cleaned and prepared for injection.
4. Using ultrasound guidance, the hydrogel is injected directly into the joint space.
5. 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:
