Knee & Patella: Radiographic Anatomy - Video Lesson

Hey, everybody. Welcome to today's lesson on radiographic anatomy, demonstrated on routine projections of the knee and patella. In a previous lesson, we discussed the anatomy of the knee and patella and which radiographic projections are routinely performed. So let's tie that information to the radiographs themselves. As a reminder, the routine radiographic projections of the knee are AP, medial oblique, lateral oblique, and lateral. Take a look at this radiograph. What projection is being demonstrated? How do you know? Let's find out the answers to these questions. If you said this radiograph is an AP projection of the knee, you're correct. We can tell this is an AP because the distal femur and proximal tibia and fibula are shown. The femoro tibial joint space is open with the articular facets of the tibia seen on end with only minimal surface area visualized. It is a true AP with no rotation as
