What is Arthrosamid?
Arthrosamid® is a treatment for knee osteoarthritis based on hydrogel technology. It is made up of 2.5% cross-linked polyacrylamide and 97.5% water. Once injected, it integrates with the synovial lining of the joint and helps restore the viscosity of the synovial fluid, improving lubrication and cushioning within the knee.
It also helps reduce inflammation, which is often a key cause of pain in osteoarthritis. By supporting the joint environment, it can help break the cycle of ongoing irritation and discomfort.
Benefits of Arthrosamid
- Long-lasting relief. Designed to cushion the joint and reduce friction, it can help people with moderate to severe knee osteoarthritis, even where other treatments have not worked. Studies show a single injection can give significant relief for up to two years.
- Better knee function. Improved lubrication helps the knee move more freely, supporting daily activities and a more active lifestyle.
- A non-surgical option. A single injection directly into the knee, without the recovery time of surgery.
- Biocompatible. A non-resorbable hydrogel that integrates with the body’s tissues and is generally well tolerated.
- Mild side effects. Side effects are usually mild and local, such as temporary discomfort where the injection was given.
- Better quality of life. Less pain and better mobility can make daily tasks and exercise easier.
Results
Clinical research shows that Arthrosamid® can reduce pain and improve joint function over the long term. Patients under 70 report close to an 80% positive response rate following treatment. For more on the research, visit Arthrosamid.
Arthrosamid® is one of several options for knee osteoarthritis. A steroid injection works quickly on inflammation, hyaluronic acid and Cingal lubricate the joint for several months, and our guide to knee injections explains the pathway.
