Viscosupplementation for knee osteoarthritis
1Duke University School of Nursing, Durham, North Carolina.
Purpose:
To provide an overview of the diagnosis and pathophysiology of osteoarthritis (OA), and to describe appropriate treatments for knee OA, with a focus on the efficacy and safety of viscosupplementation. Because nurse practitioners (NPs) can inject viscosupplements, a section on injection technique is included.
Data Sources:
Manuscripts were identified using PubMed and EMBASE with a review of the reference lists from retrieved articles.
Conclusions:
Viscosupplements are safe and effective at improving function and alleviating knee pain from OA for up to 26 weeks.
Implications For Practice:
As the number of patients with OA is increasing, NPs need to be prepared to prescribe various treatment options to alleviate osteoarthritic knee pain, including viscosupplementation.
