What are Arthrosamid® injections?

Arthrosamid® is an innovative injectable treatment for knee osteoarthritis. A single injection of Arthrosamid® provides safe, effective and sustained pain relief without the need for surgery.

Arthrosamid® is based on hydrogel technology. The non-biodegradable injection is 97.5% water combined with a 2.5% cross-linked polyacrylamide backbone. The specialist injects the hydrogel into the knee, where it works to cushion and lubricate the joint. One Arthrosamid® injection can improve the pain and stiffness of knee osteoarthritis for up to 3 years.

Who can benefit from Arthrosamid® injections?

Arthrosamid® is an approved treatment to reduce the pain and stiffness of knee osteoarthritis. It cushions and lubricates the knee joint, improving your movement and reducing discomfort. If your knee osteoarthritis is causing pain, restricting your mobility and reducing your quality of life, Arthrosamid®can provide relief without surgery.

Treatment with Arthrosamid® may not be safe if you have an infection in or around the knee, have haemophilia, take anticoagulant medication, or have had a knee arthroscopy within the past six months.

Your specialist may advise delaying or avoiding treatment if you have poorly controlled diabetes, are undergoing major dental work, or have been diagnosed with an autoimmune condition.
