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.
