Managing joint pain in osteoarthritis: safety and efficacy of hylan G-F 20

Augustine H Conduah, Champ L Baker III, Champ L Baker JrThe Hughston Foundation, Columbus, Georgia, USAAbstract: The use of intra-articular viscosupplementation in the nonoperative management of patients with osteoarthritis has become quite popular. Recent clinical data have demonstrated that the anti-inflammatory and chondroprotective actions of hyaluronic acid viscosupplementation reduce pain while improving patient function. We review the basic science and development of viscosupplementation and discuss the mounting evidence in support of the efficacy and safety profile of hylan G-F 20. Recent evidence suggesting a disease-modifying effect of hylan G-F 20 is also assessed. Furthermore, although the primary focus of this article is on treatment of osteoarthritis of the knee, we also discuss the use of viscosupplementation in other joints, such as the hip, ankle, and shoulder.Keywords: viscosupplementation, osteoarthritis, knee, hyaluronic acid, hylan G-F 20
