The tolerability of viscosupplementation: low incidence and clinical management of local adverse events.
Hylan G-F 20 (Synvisc, Genzyme Biosurgery, Ridgefield, NJ) is a visco supplement indicated for the treatment of pain due to osteoarthritis (OA) of the knee. Overall, the therapy is well tolerated with a low incidence of local and systemic adverse events (AEs). In our large clinical practice, our overall rate of local pain and swelling with treatment is consistent with that of previous reports and the product labeling. Local AEs that do occur with therapy are mostly mild to moderate in nature, transient, and resolve spontaneously or with symptomatic treatment. Local AEs thought to be related to the treatment are clinically manageable and do not result in long-term sequelae, such that their occurrence should not preclude patients from the benefit of OA pain relief with therapy, including continued pain relief with repeat treatment. Based on previous published reports of hylan G-F 20 and our extensive clinical experience, relief of OA knee pain with hylan G-F 20 far outweighs the low risk of local AEs for patients who do not respond to other therapies indicated for the treatment of OA knee pain.
