Arthrosamid® is an innovative, non-surgical single-injection treatment for knee osteoarthritis. Unlike temporary lubricant injections that degrade within months, Arthrosamid® consists of 2.5% cross-linked polyacrylamide and 97.5% sterile water—forming a permanent, biocompatible hydrogel matrix that embeds directly into the synovial lining of the knee joint.
By integrating into the joint tissue, Arthrosamid® restores elasticity, cushions cartilage, dampens friction during movement, and provides clinically demonstrated pain reduction that lasts for multiple years.
Non-Biodegradable Hydrogel Joint Cushioning
- ✓ Single Injection Treatment: Only one outpatient procedure required for multi-year mobility.
- ✓ Permanent Synovial Integration: Hydrogel embeds into the joint lining to cushion cartilage.
- ✓ Sustained Multi-Year Relief: Proven clinical efficacy lasting 3 to 5+ years post-injection.
- ✓ Postpone Knee Surgery: Excellent alternative for patients seeking to delay or avoid knee replacement.
Is Arthrosamid® Right For You?
Designed for moderate-to-severe knee osteoarthritis patients who have not found adequate relief from standard viscosupplementation.

Synovial Membrane Cushioning
Once injected, Arthrosamid® integrates into the inner synovial tissue, strengthening the joint lining and absorbing mechanical shock during walking and climbing.
Non-Degradable Biocompatible Matrix
Does not break down or absorb into the bloodstream, preserving joint lubrication and preventing bone-on-bone friction long after injection.
Real-Time Ultrasound Guidance
Administered under sterile fluoroscopic or ultrasound visualization to ensure precise intra-articular placement with maximal safety.
