Osteoarthritis of the Knee

Good. The presence of night pain, constant pain, including pain at rest and/or reduced function over time that are due to OA suggest that it is severe and that you might be headed for surgery, so it's better not to have end-stage symptoms such as these.

Do you have locking or giving way of the joint?

This question is an attempt to identify a torn or damaged ligament (such as the anterior cruciate ligament) or cartilage (called a meniscus).

Yes, I have locking and/or giving way.

No, I have no locking or giving way.
