MOVE BEYOND THE LIMITS OF KNEE PAIN

When pain begins to shape your life, it is time for a clearer plan.

Knee osteoarthritis can make walking, stairs, exercise and sleep difficult. If physiotherapy, pain relief or previous injections have not helped enough, Arthrosamid® offers a non-surgical option before considering surgery.

Arthrosamid® is a non-biodegradable, water-based hydrogel delivered as one 6 mL injection. It integrates with the joint lining to help reduce pain and stiffness and support movement, with published follow-up evidence supporting sustained improvements in pain and function for up to five years.

HOW ARTHROSAMID® WORKS

A synovial scaffold approach, not a short-term fix.

Most knee injections wear off in weeks or months. Arthrosamid® is different: a non-biodegradable hydrogel designed to integrate with the joint lining and support long-lasting improvement, as part of a clear, doctor-led treatment plan.

  • Synovial integrationThe hydrogel integrates with the synovial tissue to form a cushioning scaffold within the joint lining.
  • Helps reduce inflammationHelps calm the inflammatory environment in the joint, easing stiffness and pain.
  • Supports joint elasticity97.5% water and 2.5% polyacrylamide, designed to support smoother, more comfortable movement.
