Intra-articular hyaluronic acid (HA) injections for the symptomatic relief of pain have been available for treatment since the 1980s.

Abstract
Intra-articular hyaluronic acid (HA) injections for the symptomatic relief of pain have been available for treatment since the 1980s. Practitioner experience and real-world evidence have been accumulated to suggest that HA injections are effective and well tolerated in patients. Treatment guidelines issued by different professional medical societies, however, do not point in a single direction. This appears mainly due to conflicting results of the proposed meta-analyses at least in part associated with a variability between different HA preparations on different outcome parameters, suggesting that intra-articular HA products should not be treated as a group, as there are differences between them influencing both efficacy and safety.
