Knee Anatomy and X-ray Interpretation

Dr. Morton explains the anatomy visible in knee x-rays, focusing on AP, lateral, and sunrise views. The video covers the identification of key structures such as the femur, tibia, fibula, and patella, and discusses the joint spaces and ligaments. Each view provides a different perspective, aiding in the understanding of knee anatomy and potential injuries.

What are the three standard views used in knee x-ray anatomy?

• AP, lateral, and oblique views

• AP, lateral, and sunrise views

• AP, oblique, and axial views

• Lateral, sunrise, and axial views

In the AP view of the knee, which bone is identified as looking like a 'T'?

• Femur

• Fibula

• Patella

• Tibia

What is the function of the joint space in the AP view of the knee?

• To accommodate articular cartilage and menisci

• To connect the femur and fibula

• To provide structural support

• To allow for muscle attachment

Which bone is described as a sesamoid bone in the lateral view of the knee?

• Patella

• Fabella

• Tibia

• Fibula

In the lateral view, where is the fabella typically located?

• In the medial tendon of the gastrocnemius

• In the lateral tendon of the gastrocnemius

• In the anterior tendon of the quadriceps

• In the posterior tendon of the hamstrings

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

• The femoral condyles

• The patellar tendon

• The femoral patellar joint

• The tibial plateau

What does the trochlear groove resemble in the sunrise view?

• A ball

• A hinge

• A socket

• A pulley

Which ridge is part of the edge of the lateral condyle of the femur in the sunrise view?

• Lateral trochlear ridge

• Posterior trochlear ridge

• Anterior trochlear ridge

• Medial trochlear ridge

What is the significance of the intercondylar eminence in knee anatomy?

• It supports the patella

• It connects the femur and fibula

• It is where the ACL and PCL attach

• It is the insertion point for the quadriceps

What is the primary purpose of reviewing knee x-rays?

• To evaluate skin conditions

• To measure bone density

• To diagnose muscle injuries

• To assess joint space and bone alignment
