Definition & Symptoms of OSTEOARTHRITIS

Definition
By Mayo Clinic staff

Osteoarthritis, sometimes called degenerative joint disease or osteoarthrosis, is the most common form of arthritis. Osteoarthritis occurs when cartilage in your joints wears down over time.

Osteoarthritis can affect any joint in your body, though it most commonly affects joints in your hands, hips, knees and spine. Osteoarthritis typically affects just one joint, though in some cases, such as with finger arthritis, several joints can be affected.

Osteoarthritis gradually worsens with time, and no cure exists. But osteoarthritis treatments can relieve pain and help you remain active. Taking steps to actively manage your osteoarthritis may help you gain control over your osteoarthritis pain.

Osteoarthritis of the spine

Osteoarthritis of the hip


Osteoarthritis symptoms often develop slowly and worsen over time. Signs and symptoms of osteoarthritis include:

Pain in a joint during or after use, or after a period of inactivity

Tenderness in the joint when you apply light pressure

Stiffness in a joint, that may be most noticeable when you wake up in the morning or after a period of inactivity

Loss of flexibility may make it difficult to use the joint

Grating sensation when you use the joint

Bone spurs, which appear as hard lumps, may form around the affected joint

Swelling in some cases

Osteoarthritis symptoms most commonly affect the hands, hips, knees and spine. Unless you've been injured or placed unusual stress on a joint, it's uncommon for osteoarthritis symptoms to affect your jaw, shoulder, elbows, wrists or ankles.
