Anatomy of Knee X-rays

Dr. Morton explains the anatomy visible in knee X-rays, focusing on the AP, lateral, and sunrise views. He describes the bones and structures seen in each view, such as the femur, patella, tibia, fibula, and joint spaces. The AP view highlights the femoral condyles and tibial plateaus, while the lateral view shows the fabella and cruciate ligament attachments. The sunrise view focuses on the patella and trochlear groove. The video emphasizes the importance of smoothness and joint space in assessing knee health.

In the AP view of the knee, which bone is identified as the large bone that resembles a 'T'?

• Femur

• Patella

• Tibia

• Fibula

What is the function of the intercondylar eminence in the knee joint?

• It serves as an attachment for the cruciate ligaments

• It supports the patella

• It is a part of the fibula

• It connects the femur and tibia

Which structure is known as a sesamoid bone found in the lateral tendon of the gastrocnemius?

• Fibula

• Fabella

• Tibial tuberosity

• Patella

In the lateral view, what is the significance of the tibial tuberosity?

• It is the insertion point for the quadriceps

• It is a part of the patella

• It supports the fibula

• It is where the femur articulates

What is the primary focus when examining the sunrise view of the knee?

• The alignment of the fibula

• The smoothness of the femoral condyles

• The space in the femoral patellar joint

• The size of the tibia

Which ridge is part of the border of the medial femoral condyle in the sunrise view?

• Patellar ridge

• Intercondylar ridge

• Medial trochlear ridge

• Lateral trochlear ridge

What does the term 'trochlea' refer to in the context of the knee anatomy?

• A pulley-like structure

• A type of cartilage

• A ligament

• A bone
