When knee osteoarthritis occurs, the hyaluronic acid in the synovial joint fluid becomes depleted, reducing the fluid’s lubrication and shock-absorbing properties.6

This hyaluronic acid depletion is associated with increased inflammation that can degrade knee cartilage and cause pain when you move the joint.6

Injected directly into the knee, hyaluronic acid treatments restore the shock-absorbing properties of the synovial fluid, relieving osteoarthritis pain longer than painkillers, and with fewer side effects.9,10 Injections are usually administered in a doctor’s office, and the entire procedure takes only a few minutes. Most patients say they feel little or no discomfort. Treatments can range from a single injection to one injection a week for three to five weeks.


Choosing HA gives you more freedom from pain today, better options tomorrow

It typically takes between 2 to 5 weeks before a patient experiences the full benefits of hyaluronic acid.20 But hyaluronic acid treatments have been proven to provide much longer-lasting pain relief — up to 6 months9,10 — than oral pain medications or steroid injections. Plus, hyaluronic acid treatments can be safely repeated without the risks of side effects from painkillers or repeated steroid injections.

Hyaluronic acid also may do more than relieve osteoarthritis pain longer: a 2015 clinical study has shown that hyaluronic acid treatments can substantially delay the need for knee replacement surgery.24
