Intra-articular injection of etanercept versus glucocorticoids in rheumatoid arthritis patients.

Intra-articular injection of etanercept is a safe and promising option; with comparable results to intra-articular injection of corticosteroid; however, its rapid absorption from the synovium may necessitate frequent injections. Key Points • Persistent inflammatory mono-arthritis is a common clinical problem that is often difficult to treat; it is a debilitating and destructive condition. • Intra-articular injection of TNF inhibitors is an encouraging treatment modality in managing refractory mono-arthritis in rheumatoid arthritis.
