How your doctor diagnoses osteoarthritis (OA) of the knee

At some point after you realize you have knee pain or limited ability to move your knee, you will make an appointment with your doctor. Good for you. It is important to know exactly what is causing your knee pain. If osteoarthritis (OA) is the cause, you and your doctor will need to know the extent of the damage to your bones and cartilage.

To find these answers, your doctor will ask about your symptoms; observe how well you can move your knees; ask where the pain is, how long you’ve had it, whether you hear any “crunching” or “popping” sounds, and what types of movements and activities make the pain better or worse. Yes, “crunching” and “popping” noises, also called crepitus (pronounced kreh’-pit-tuss), may be symptoms of your OA.1-3
