What is a Hyaluronic Acid Injection?

How Does Hyaluronic Acid Work?

Healthy joint fluid is thick and slippery. In osteoarthritis the amount and quality of hyaluronic acid decrease, the fluid thins and joint surfaces rub more. Injected hyaluronic acid restores viscosity, reduces friction and helps calm inflammation inside the joint.

Who Is It For?

• Patients with early to moderate knee osteoarthritis
• Patients whose pain persists despite medication and physiotherapy
• Patients who want to delay surgery or are not suitable for it
• In selected patients, the hip, shoulder and ankle joints
