What are the symptoms of OA?

Pain is the most frequent symptom of OA. Other common symptoms are morning stiffness in the joint, limited range of movement, and crepitus (a crackling sound or feeling) when the joint is moved.

The pain of osteoarthritis is described as a sharp ache or burning sensation that worsens with use. Pain increases as cartilage erodes and bone surfaces lose their protection. The chronic pain and stiffness leads to decreased movement, which in turn allows the muscles to atrophy and ligaments to become lax.
