Osteoarthritis symptoms and severity vary—no two patients experience osteoarthritis the exact same way. The most common signs and symptoms of osteoarthritis17 include:

  • Sore, painful joints
  • Joint stiffness and swelling
  • A grating sensation when you move your joint
  • Decreasing range of motion and flexibility

Because osteoarthritis symptoms worsen over time, early diagnosis and proactive therapies can help keep you physically active longer without pain. If osteoarthritis is left untreated, increasing stiffness and discomfort in the joint may start to limit everyday activities.11,19

Even mild to moderate osteoarthritis knee pain can stop you in your tracks.

In a healthy knee, thick synovial fluid lubricates and cushions the joint, protecting it from damage. But when osteoarthritis strikes, the synovial fluid loses hyaluronic acid and becomes thin and weak. This fluid depletion not only magnifies osteoarthritis pain, it intensifies inflammation and stiffness, limiting knee strength and movement and accelerating progressive joint damage.
