Abstract:
Hyaluronic acid (HA) injections relieve pain more than placebo. The effect is small but similar to results from oral nonsteroidal anti-inflammatory drugs (NSAIDs) or steroid injection. The various HA products all appear to be equally effective in reducing pain. Data concerning the effect of HA on functional ability are conflicting.
