Move Freely, Live Fully with Arthrosamid®
Experience long-lasting, proven pain relief for knee osteoarthritis with a single injection—no surgery required.
Long-Lasting Relief for Knee Osteoarthritis
Arthrosamid® is a cutting-edge, non-surgical treatment designed to relieve the pain and discomfort associated with knee osteoarthritis. This innovative polyacrylamide hydrogel is injected directly into the knee joint where it permanently integrates with the synovial lining, becoming part of the joint membrane. In early and severe osteoarthritis, the synovial membrane becomes a cytokine storm of inflammatory cells causing stiffness and pain. Arthrosamid® works through a natural filtering process where the synovium uptakes the inert hydrogel, reducing inflammation and stiffness while improving joint elasticity. This single injection can provide long-lasting pain relief, helping you return to the activities that matter most.

Reclaim Your Active Lifestyle
Knee pain doesn't just affect your mobility—it impacts every aspect of your life. From simple daily tasks like climbing stairs to enjoying walks with loved ones or pursuing your favorite hobbies, chronic knee osteoarthritis can steal the moments that matter most.
Arthrosamid® offers a solution that goes beyond temporary pain relief. By integrating into your joint tissue and providing lasting cushioning, this innovative treatment helps you rediscover the freedom to move confidently and live life on your terms—without the need for major surgery or frequent repeat injections.

How Arthrosamid® Works
A revolutionary approach to treating knee osteoarthritis
Arthrosamid® is a synovial scaffold that permanently combines with the synovial lining in the knee. In early stage and severe osteoarthritis, this membrane becomes a cytokine storm of inflammatory cells causing stiffness and pain. Once injected via ultrasound, Arthrosamid® takes 4-6 weeks and out to 3 months to have a clinical effect—this is a physical, biological process. The natural filtering process of the synovium uptakes the inert hydrogel, and over time it becomes integrated, reducing inflammation and stiffness while improving the elasticity of the joint. The result is sustained pain relief and improved joint function that can last for years from a single injection.
Synovial Integration
Hydrogel permanently combines with synovial membrane through natural filtering process
Reduces Inflammation
Reduces cytokine storm of inflammatory cells in synovial lining
Improves Elasticity
Integration process improves elasticity of the joint over time
Long-Term Relief
Up to 5 years of sustained pain relief from single injection
What to Expect During Your Arthrosamid® Treatment
Simple outpatient procedure
Step
Duration
Pre-Treatment Preparation
You'll be given two antibiotics before the procedure. The treatment area will be thoroughly cleaned and a local anaesthetic will be applied to numb your knee.
Step
Duration
Injection Procedure
Under ultrasound guidance, any excess fluid is removed from the knee joint before the Arthrosamid® hydrogel is precisely injected into the joint cavity.
Step
Duration
Post-Treatment Care
Brief observation period followed by post-treatment care instructions and advice on activity restrictions for the first few days.
The Science Behind Arthrosamid®
Arthrosamid® is a non-biodegradable polyacrylamide hydrogel composed of 97.5% water and 2.5% cross-linked polymer. When injected into the knee joint, it permanently combines with the synovial lining, becoming a permanent part of the joint membrane structure.
The mechanism of action is a physical, biological process. In early stage and severe osteoarthritis, the synovial lining becomes a cytokine storm of inflammatory cells causing stiffness and pain. Once injected via ultrasound, the natural filtering process of the synovium uptakes the inert hydrogel over 4-6 weeks and out to 3 months. As it becomes integrated, it reduces inflammation and stiffness while improving the elasticity of the joint.
This unique approach addresses the inflammatory cascade in the osteoarthritic joint rather than simply masking symptoms. By integrating with the synovial membrane and reducing the cytokine storm of inflammatory cells, Arthrosamid® delivers sustained pain relief and functional improvement.
The clinical evidence is robust. To date, 23,000 patients across the UK and Europe have been treated with Arthrosamid®, supported by 4 clinical studies demonstrating multiple years of sustained pain relief. Two of these clinical studies demonstrate sustained pain relief for up to 5 years from a single injection.

EXPERT PERSPECTIVE
A Game-Changer in Knee Osteoarthritis Management
Understanding Arthrosamid's unique mechanism of action
For years, patients with knee osteoarthritis faced limited options: manage pain with medications and repeated injections, or undergo joint replacement surgery. Arthrosamid® has changed this paradigm entirely.
What makes Arthrosamid® unique is its mechanism of action. In early stage and severe osteoarthritis, the synovial lining becomes a cytokine storm of inflammatory cells causing stiffness and pain. This non-biodegradable polyacrylamide hydrogel permanently combines with the synovial membrane. Once injected via ultrasound, the natural filtering process of the synovium uptakes the inert hydrogel over 4-6 weeks to 3 months. As it integrates, it reduces inflammation and stiffness while improving the elasticity of the joint—addressing the biological process at its source.
Clinical evidence is compelling. Over 23,000 patients across the UK and Europe have been treated, supported by 4 clinical studies. Pain improvements typically begin at 4-6 weeks, with 2 studies demonstrating sustained pain relief for up to 5 years from a single injection. This longevity, combined with the minimally invasive nature of the procedure, makes Arthrosamid® an excellent option for patients seeking to delay or avoid knee replacement surgery while maintaining an active lifestyle.
