Hyaluronic acid injection

Some hyaluronic acid is already in the fluid in your joints. In people with osteoarthritis, the hyaluronic acid gets thinner. When this happens, there isn't enough hyaluronic acid to protect the joint. Injections can put more hyaluronic acid into your knee joint to help protect it.

Hyaluronic acid injections may give you more pain relief than oral medicines. These injections can help the pain stay away for 6 months to a year, sometimes longer. Unfortunately, these injections don't help everyone.
