Fast Five Quiz: Knee Osteoarthritis Presentation and Diagnosis

James Monroe Laborde, MD, MS

The presentation of knee OA varies greatly from person to person. Typically, OA presents in patients > 45 years of age as a triad of symptoms: gradual deep, achy joint pain, stiffness, and restricted joint movement. Pain is often usage-related and relieved with rest. In addition, patients may describe morning stiffness lasting < 30 minutes, muscle weakness, and instability. If the disease progresses, pain may affect activities of daily living; patients often report difficulty in performing daily tasks, such as climbing stairs or rising from a chair.

Prolonged stiffness lasting > 1 hour, rapidly progressive joint pain, and joint swelling may indicate an alternative underlying pathology and warrant additional testing.
