Hyaluronic Acid (HA) injections- sometimes called viscosupplementation- are used to help reduce pain and improve mobility in joints affected by osteoarthritis. HA is a naturally occurring substance in joint fluid that helps cushion , lubricate, and protect the joint.
HA is a gel-like substance that helps joints move more smoothly. As arthritis progresses, the natural HA in the joint becomes thinner and less effective. An HA injection adds more of this cushioning fluid to the joint, helping reduce pain and stiffness.
Common reasons to consider an HA injection:
- Knee osteoarthritis (most common)
- Stiffness, catching, or grinding sensation
- Pain that limits walking, exercise, or daily activities
- When other treatment or medications haven’t provided enough relief
Integrating physiotherapy and a strengthening program often enhances the benefits of HA injections and helps protect joint health long-term.
