Product Overview & Description
GELSYN-3® (2.25 mL) is a 3-injection hyaluronic acid (HA) viscosupplementation therapy designed for the targeted relief of knee pain caused by osteoarthritis (OA). Formulated to replenish degraded synovial fluid, GELSYN-3 delivers essential joint lubrication and cushioning directly into the knee joint—helping restore natural mobility, protect joint function, and delay the need for invasive knee surgery.
Indicated for patients who have not obtained adequate relief from conservative non-pharmacological therapies or simple analgesics, GELSYN-3 provides clinically proven, long-lasting pain relief for up to 6 months following a complete 3-injection treatment regimen.
