Intra-Articular Injection in Moderate Knee Osteoarthritis

Intra-Articular Injection in Moderate Knee Osteoarthritis

AqueousJoint is a new intra-articular (IA) injectable joint lubricant for patients suffering from knee Osteoarthritis developed by Liposphere LTD.

AqueousJoint is a liposomal boundary lubricant, which coats the cartilage surface and protects it from further damage and degradation. The product goal is restoring cartilage its natural bio-lubrication properties.

AqueousJoint is a surface lubricant that does not change the synovial fluid mechanical characterization but provides hydration protection from cartilage degradation and wear.
