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.

Knee gel injections, such as polyacrylamide hydrogel (Arthrosamid), offer targeted relief for osteoarthritis by lubricating and cushioning the knee joint, improving movement and reducing pain. Preparation involves consulting your healthcare provider about medications and arranging transport. The procedure, guided by ultrasound and typically lasting 15–30 minutes, may cause minor discomfort but significantly lowers pain scores within three months. Post-injection care includes rest, ice application, and monitoring for infection. Gradual return to activities with low-impact exercises supports recovery, with studies showing sustained patient satisfaction up to a year. Following expert advice and aftercare ensures effective treatment and enhances quality of life.
