Disease-modifying therapeutic strategies in osteoarthritis: current status and future directions

Abstract

Osteoarthritis: moving from symptom relief towards disease control Researchers are exploring several promising avenues to develop treatments for osteoarthritis that control or reverse its progress, rather than simply relieving the symptoms of inflammation and pain. These new opportunities are emerging from increased understanding of the molec_reular mechanisms underlying the onset and progression of osteoarthritis. Seung-Baik Kang, Jin-Hong Kim and colleagues at Seoul National University, South Korea, review the current status and future directions of disease-modifying strategies that are already showing promise in clinical trials. They discuss approaches aimed at restricting the damage to joint cartilage by controlling the inflammatory signaling molecules, enzyme actions and molecular pathways that cause cartilage to degenerate. They also consider treatments that could stimulate the active regeneration of damaged cartilage. They conclude that some approaches will soon be ready to move into general clinical use.
