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

Abstract: 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 di… Show more

“…As the main component of intra-articular synovial fluid, HA is present in the upper layer of articular cartilage 1-2 microns. 28 Compared with normal knees containing 2.5 to 4 mg/mL of HA, the knee of patients with osteoarthritis has a decrease of 1 to 2 mg/mL due to reduced production of HA and increased self-degradation and clearance, with a reduction of up to 50%. 27 Since it was approved by Food and Durg Administration (FDA) for the treatment of OA in the United States in 1997, hyaluronic acid has been widely used.…”

“…Since during the knee OA the degradation of synovial fluid hyaluronate occurs, therefore it has been assumed that the intra-articular injection of HA could ameliorate the functional impairment and knee joint pain. In this regard, HA has been considered as a pharmacologic option and was approved by the FDA for knee OA in 1997 and recommended as an effective treatment for knee OA in the guideline of the American College of Rheumatology in 2000 [ 16 , 17 ]. However, due to the controversial results, there is no agreement regarding the management of knee OA with intra-articular HA injections.…”

“…31 As part of the physiologic synovial fluid, HA performs not only mechanical functions by maintaining the viscoelasticity of the synovial fluid, but also chondroprotective and anti-inflammatory functions. [31][32][33][34] As the concentration of native HA is reduced to approximately 50% of its physiologic concentration in OA, 35 an intraarticular injection of HA exhibits instant dual mechanical effects. As such, it functions as a lubricant during slow, low shear rate movements by increasing synovial viscosity and also provides shock absorption during rapid, high shear rate movements in its structure as an elastic solid.…”
