What is the difference between Arthrosamid injection and hyaluronic acid? 

Hyaluronic acid is a naturally occurring substance found throughout the body, including in the synovial fluid within joints. When injected, it helps replenish the body’s own supply, often easing pain and improving joint movement. However, its effects on knee osteoarthritis tend to be short-lived, typically lasting less than 6 months, so treatments must be repeated regularly. 

Arthrosamid, by contrast, is a safe, synthetic hydrogel made up of 2.5% cross-linked polyacrylamide and 97.5% water. Because it’s non-biodegradable, the body does not break it down, allowing its benefits to last much longer. Its safety and effectiveness are supported by more than 20 years of research.
