Introduction If you suffer from knee osteoarthritis, you may have heard about Arthrosamid — a new injectable treatment that’s gaining attention in the UK. But what exactly is it, and how does it work?
What Is Arthrosamid? Arthrosamid is a non-biodegradable hydrogel made of 2.5% cross-linked polyacrylamide and 97.5% water. It’s injected directly into the knee joint to relieve pain caused by osteoarthritis. It was originally developed for other medical uses, including urology and cosmetic procedures, and has now been repurposed and approved for treating joint pain.
How Does It Work? Once injected, the hydrogel integrates into the synovial membrane (the soft tissue lining the joint), improving joint lubrication and cushioning. This helps to reduce inflammation and pain. Unlike traditional treatments that wear off or require multiple doses, Arthrosamid stays in the joint, acting as a lasting cushion against the wear and tear of osteoarthritis.
Why Is It Considered Revolutionary? Unlike steroid injections, which wear off in a few months, or hyaluronic acid, which has variable results, Arthrosamid offers long-term relief with just one injection. It also avoids the systemic side effects of oral anti-inflammatory medications and is less invasive than knee replacement surgery, making it a compelling middle-ground option.
Who Might Benefit? Patients with mild to moderate osteoarthritis who aren’t ready for surgery but want longer-term relief than traditional injections may find Arthrosamid ideal. It’s also suitable for patients looking for an alternative to repeated steroid use or those whose symptoms persist despite physiotherapy and lifestyle changes.
Conclusion Arthrosamid represents a major step forward in non-surgical management of knee osteoarthritis. With a strong safety profile and long-lasting results, it is increasingly being considered as a first-line injectable treatment for appropriate patients. Speak to your orthopaedic specialist to see if it’s right for you.
