Product Overview & Description
SUPARTZ FX® (2.5 mL) is a proven, 5-injection hyaluronic acid (HA) viscosupplementation therapy engineered for the targeted relief of knee pain caused by osteoarthritis (OA). Derived from high-purity sodium hyaluronate, SUPARTZ FX replenishes degraded synovial fluid directly within the joint capsule—restoring essential cushioning, shock absorption, and smooth articulation.
Trusted by doctors and millions of knee OA patients worldwide, SUPARTZ FX provides an effective, flexible, and affordable non-surgical treatment option. It provides long-lasting joint pain relief, reduces stiffness, and restores mobility while helping patients delay the need for invasive total knee replacement surgery.
