Conventional medical therapy for osteoarthritis: current state of the evidence.

PURPOSE OF REVIEW: The incidence and prevalence of osteoarthritis at the knee, hip, and hand joints are rising. Knowledge about recent developments in the treatment of osteoarthritis is highly relevant to current medical and rheumatology practice. This review will highlight key findings from the published literature in the past 18 months, identified via a PubMed search, including the context for these studies, their key findings, and implications.

RECENT FINDINGS: Main themes from the literature covered by this article include a continued focus on acetaminophen and glucosamine-chondroitin as therapeutic agents in the medical management of osteoarthritis. In addition, there is a relatively novel focus on use of adalimumab, a tumor necrosis factor inhibitor, and on strontium ranelate, in relation to outcomes of pain and structural progression in osteoarthritic joints.

SUMMARY: Recent studies convey a continued focus on potential therapeutic benefit derived from a combination of glucosamine-chondroitin, and intrigue the reader with a focus on biologic therapy (i.e. tumor necrosis factor antagonist) for osteoarthritis, and with use of strontium ranelate as a newer agent with potential therapeutic benefit.
