A Long-Lasting Solution for Knee Osteoarthritis

Arthrosamid® is an innovative, non-surgical treatment for knee osteoarthritis, designed to provide long-lasting pain relief and improved joint function. Unlike traditional treatments that may require frequent repeat injections, Arthrosamid® offers a unique and lasting approach — with a single injection shown to be effective for up to four years.

What is Arthrosamid®?

Arthrosamid® is a non-biodegradable hydrogel implant made of 97.5% water and 2.5% cross-linked polyacrylamide. It is injected directly into the knee joint, where it forms a permanent, soft, cushioning scaffold within the synovial membrane — the natural lining of the joint.

How Does It Work?

Once injected, Arthrosamid® integrates with the synovial membrane, helping to:

Reduce inflammation within the joint lining.
Restore joint lubrication and improve shock absorption.
Alleviate pain and stiffness caused by osteoarthritis.
Enhance mobility and overall joint function.

By acting directly on the synovial membrane, Arthrosamid® not only cushions the joint but also modifies the disease process, providing relief beyond what traditional hyaluronic acid or corticosteroid injections can offer.

What Makes Arthrosamid® Different?

Permanent Implant: Unlike other injectable treatments, Arthrosamid® is not broken down or absorbed by the body, meaning it continues to work over time.
Clinically Proven: Studies show significant reductions in knee pain and improved function that can last up to 4 years after a single injection.
Non-Surgical: It’s a minimally invasive procedure performed in-clinic, making it a great alternative for patients who want to delay or avoid knee replacement surgery.
Safe and Well-Tolerated: Arthrosamid® has been shown to have a strong safety profile, with most patients experiencing minimal side effects.

Who is Arthrosamid® Suitable For?

Arthrosamid® is suitable for adults with moderate to severe knee osteoarthritis who are looking for long-term relief from pain and reduced reliance on short-term treatments. It may also be an option for those who are not yet ready or suitable for joint replacement surgery.
