Intra-articular corticosteroids in the treatment of juvenile idiopathic arthritis: Safety, efficacy, and features affecting outcome. A comprehensive review of the literature.

Intra-articular corticosteroid injection (IACI) has been used in the treatment of inflammatory arthritis in adults for over fifty years. Over the last two decades, IACI has become an important tool in the management of juvenile idiopathic arthritis (JIA), particularly in the oligoarthritis subset of JIA. Many factors may affect the efficacy of this treatment modality, although the majority of evidence on this topic is anecdotal, nonconvincing, or conflicting. The review examines the rationale, efficacy, safety, and application of the use of IACI in the treatment of JIA, focusing on factors that affect the outcome following IACI.
