What Is Arthrosamid®?
Arthrosamid® is a single, minimally invasive injection that cushions and lubricates the knee joint, helping reduce pain and stiffness caused by osteoarthritis.
Unlike steroids or hyaluronic acid, Arthrosamid works by forming a soft hydrogel within your joint — providing long-lasting cushioning that helps you move more freely.
Why Choose Arthrosamid®?
✔ Long-lasting relief – One injection can provide improvement for up to two years.
✔ Non-surgical – No need for hospital stays or joint replacement.
✔ Clinically proven – CE-marked and backed by published evidence.
✔ Safe & biocompatible – Hydrogel that integrates naturally with your joint tissue.
Who Is It For?
Arthrosamid may be right for you if:
-
You have knee osteoarthritis and ongoing pain or stiffness
-
You’ve tried other injections (steroid or hyaluronic acid) with limited success
