Hyaluronic acid is a molecule found naturally throughout the human body. It is an important component of joint fluid, called synovial fluid, which provides lubrication and cushioning for normal, healthy knees.
When you have osteoarthritis of the knee, the hyaluronic acid breaks down and becomes diluted. This reduces its natural elastic properties, which can further degrade cartilage tissue and cause increased joint pain.15
The hyaluronic acid in DUROLANE has the same composition as the natural hyaluronic acid your body produces, but it’s in a highly concentrated formulation that’s been uniquely stabilized to help resist the degradation caused by osteoarthritis.10 DUROLANE is administered as a single-injection directly into the knee.13
