Viscosupplementation with hyaluronic acid in the treatment for cartilage lesions: A review of current evidence and future directions

Diseases involving the articular cartilage are one of the leading causes of physical impairment among the adult population. While surgical technique and advancement have allowed us effective means at treating these diseases, this is not without significant risk and morbidity. With a very solid safety profile, viscosupplementation with hyaluronic acid (HA) derivatives has become an excellent modality for treating diseased articular cartilage. Recent literature supports the use of HA not only in the management of the pain associated with osteoarthritis but also as a disease-modifying agent as well. Further studies have started to define exciting new roles for viscosupplementation in the treatment for acute injuries to the joint microenvironment. © 2012 Springer-Verlag.
