## What it is

The most thorough plain X-ray of the knee, using four or more separate angles. The extra projections map the joint from several directions, which is what an orthopedic surgeon wants when planning treatment or measuring how much cartilage is left. Shorter one-or-two-view and three-view knee studies are coded separately.
