What is Arthrosamid?
Arthrosamid is an injectable non-biodegradable polyacrylamide hydrogel (iPAAG) that integrates permanently into the synovial membrane.
How It Works
Consisting of 2.5% cross-linked polyacrylamide and 97.5% water, it restores cushioning and reduces inflammation long-term.
Clinical Evidence
- Significant pain reduction maintained at 2 and 4-year follow-up
- Over 10,000 patients treated worldwide
- No serious adverse events in clinical trials
