On physical examination, findings consistent with OA are mostly limited to the affected joint. Bony enlargement has been shown to be 95% specific for knee OA.

Other physical examination findings of knee OA include:

  • Crepitus

  • Limited range of motion

  • Joint tenderness

  • Pain with passive movement

  • Gait abnormalities

  • Muscle atrophy

Unlike inflammatory, infectious, and crystalline causes of knee arthritis, warmth and effusions are typically absent or small in the knee OA.
