What Are the Symptoms of Osteoarthritis?
Osteoarthritis symptoms and severity vary—no two patients experience osteoarthritis the exact same way. The most common signs and symptoms of osteoarthritis include:26
- Sore, painful joints
- Joint stiffness and swelling
- A grating sensation, or clicking or popping sound when you move your joints
- Decreasing range of joint motion and flexibility
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.15 But when osteoarthritis strikes, the synovial fluid loses hyaluronic acid and becomes thin and weak.18 This fluid depletion intensifies inflammation and stiffness which limits knee strength and movement and accelerates progressive joint damage.5,11,24
