Hyaluronic acid injection is used to treat knee pain caused by osteoarthritis (OA) in patients who have already been treated with pain relievers (e.g., acetaminophen) and other treatments that did not work well.
Hyaluronic acid is similar to a substance that occurs naturally in the joints. It works by acting like a lubricant and shock absorber in the joints and helps the joints to work properly.
