Arthrosamid is a polyacrylamide hydrogel developed by Contura International Ltd. as a long-lasting intra-articular injection approved in Europe for the treatment of knee osteoarthritis (OA). The treatment has the potential to change the present care pathway for managing osteoarthritis, which affects around one in four adults in Ireland aged over 601 (over 400,000 people)2 and current treatments are not long lasting or involve invasive knee replacement surgery. Despite a large suffering population, there has been very little innovation in the range of osteoarthritis treatments on offer to meaningfully help patients – until now.
