What is an Arthrosamid® Injection?
Arthrosamid® is a non-surgical, injectable treatment specifically developed for people suffering from knee osteoarthritis (OA). Unlike traditional treatments that often rely on repeated medications or invasive surgery, Arthrosamid® offers a long-lasting solution through a single injection.
At the core, Arthrosamid® is a permanent hydrogel implant. This hydrogel is made up of 97.5% water and 2.5% cross-linked polyacrylamide, designed to integrate safely into the soft tissue of the knee. Once injected into the intra-articular space of the knee joint, it cushions and lubricates the joint, providing relief from pain, inflammation, and stiffness associated with osteoarthritis.
Who is Arthrosamid® suitable for?
Suitable for patients with mild to moderate knee osteoarthritis
Experiencing persistent knee pain, stiffness or swelling
Seeking a non-surgical treatment with long-lasting relief
Have had limited success with other treatments (e.g. steroid or hyaluronic acid injections)
Looking to postpone or avoid knee replacement surgery
How does the Arthrosamid® Injection Work?
After a single injection, Arthrosamid® forms a durable, gel-like cushion within the knee joint.
This cushion helps:
Reduce pain and swelling
Improve joint function and mobility
Delay or avoid the need for surgery
The hydrogel also interacts with the synovial membrane (the lining of the joint), modifying the joint environment in a way that promotes long-term relief rather than short-term symptom suppression.
