Introducing Arthrosamid®
Arthrosamid® is a non-biodegradable injectable polyacrylamide hydrogel (2.5% iPAAG) implant consisting of 2.5% cross-linked polyacrylamide and 97.5% water. It is administered via a simple, one-step procedure performed under local anaesthesia by a qualified physician, such as an orthopaedic surgeon or rheumatologist1 — ensuring you’re in and out of the clinic the same day. Arthrosamid® is proven to maintain a significant, long-lasting reduction in knee OA pain2,3— even five years post-treatment.2
How does Arthrosamid® work?
Arthrosamid® is the first and only permanent injectable implant that integrates with the knee’s synovial tissue,4 forming a scaffold that softens and increases tissue elasticity. This leads to decreased joint stiffness, reduced pain, and improved knee function.5,6,7
