What is Viscosupplementation?

Viscosupplementation is a medical treatment that injects hyaluronic acid (HA) directly into an arthritic joint. Hyaluronic acid is a natural substance found in healthy joint fluid that provides cushioning and lubrication.

When you have osteoarthritis, your joint fluid becomes thinner and less effective. HA injections help restore the natural cushioning, reducing pain and improving mobility without surgery.

Fluoroscopic Guidance: Why It Matters

Studies show that blind injections miss the target up to 30% of the time. Fluoroscopic (X-ray) guided injections ensure the medication reaches exactly where it's needed.

What to Ask Your Provider

"Do you use imaging guidance for joint injections?" Fluoroscopic or ultrasound guidance significantly improves accuracy and outcomes.
