Understanding Hyaluronic Acid Injections
Hyaluronic acid is a substance that occurs naturally within healthy joint fluid and helps with lubrication and shock absorption. In osteoarthritis, the quality of joint fluid can change, contributing to pain and stiffness. Hyaluronic acid injections, sometimes called viscosupplementation, aim to improve joint lubrication and movement.
They are most commonly used for knee osteoarthritis but may be considered for other joints in selected cases.
