Hyaluronic acid injection is used to treat knee pain caused by osteoarthritis (OA) in patients who have already been treated with pain relievers.
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.
This medicine is to be administered only by or under the immediate supervision of your doctor.
When you have osteoarthritis (OA) in the knees, for instance, the hyaluronic acid in the affected joint gets thinner. Hyaluronic acid gel injections act as a lubricant so the joint works more smoothly. The hyaluronic acid from these injections may also reduce inflammation in the joint and therefore joint pain and swelling.
