Hyaluronic Acid Joint Injections

Hyaluronic Acid (HA) injections are a non-surgical treatment option for joint pain, particularly in osteoarthritis.

They are designed to provide long-lasting relief and improve joint function by adding lubrication and shock absorption to the joint. While generally safe, there are potential side effects to be aware of, and some precautions should be taken. 

What is it?

  • Hyaluronic acid (HA) is a naturally occurring substance in the body, including the synovial fluid of joints. 

 

  • In osteoarthritis, the hyaluronic acid in the joint can thin out, leading to pain and stiffness. 

 

  • HA injections supplement the body’s natural supply, restoring lubrication and shock absorption. 

What happens during the injection?

  • The injection is typically performed in a joint, often guided by ultrasound to ensure accurate placement. 

 

  • A local anesthetic may be used to numb the area, but some pain or discomfort may still be felt. 

 

  • The injection process is generally quick and relatively painless. 

What happens after the injection?

  • It may take several days or weeks for the HA to start working. 

 

  • Some patients may experience temporary pain, swelling, or stiffness at the injection site.

 

  • It’s recommended to avoid strenuous activity for a few days after the injection to minimize discomfort. 

Potential side effects and precautions:

  • Common side effects include pain, swelling, and redness at the injection site, which are usually temporary. 

 

  • Rarely, more serious side effects like infection or a flare-up of arthritis can occur. 

 

  • If you are taking blood thinners, discuss this with your doctor as it may affect the injection. 

 

  • If you are pregnant or breastfeeding, consult with your doctor before having an HA injection. 

 

  • You should avoid strenuous activity for a few days after the injection. 

 

  • If you experience any unusual symptoms or complications after the injection, contact your doctor immediately.
