About 528 million

people worldwide were living with osteoarthritis in 2019; an increase of 113% since 1990.

The Problem

Despite osteoarthritis (OA) being the most common type of arthritis and the fastest-growing cause of disability worldwide,  the treatment area has seen minimal progression in the last 20 years. With so little known about exactly what causes knee OA, a permanent cure has yet to be discovered.

Redefining treatment for knee OA, without surgery

Arthrosamid® is a non-biodegradable 2.5 iPAAG injectable implant that delivers long-lasting pain relief — improving the quality of life for patients with knee OA.
