Clinical inquiries. Do hyaluronic acid injections relieve OA knee pain?
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.
