What Is OA
Knee Pain?

Osteoarthritis (OA) knee pain is common
You’ve been diagnosed with OA knee pain. You’re not alone, since 46% of people are at risk of developing OA knee pain during their lifetime.2

How does OA knee pain happen?

A healthy knee joint is protected by hyaluronic acid (HA), a natural gel-like fluid that helps cushion bones and joint tissue.3 Without enough of this protective fluid, your cartilage begins to wear away.4,5 The result is knee pain and stiffness.5

The daily grind

When cartilage loss is severe and HA is depleted, the bones in your knee may grind together. This friction, which wears down the joints, can cause knee pain and stiffness to get even worse.4,5,6 Unfortunately, patients with OA knee pain feel the effects of this loss every day. One way to get relief is with treatment.7
