MRI Knee (Anatomy) - Video Lesson

Hey, everyone. Welcome to today's lesson on the MRI of the knee. In this lesson, we will look at the bony structures of the joint, important ligaments and tendons, and anatomy on different planes of MRI imaging. Let's get started. The knee joint is classified as a synovial hinge joint with some capacity for rotation, allowing primarily flexion and extension, and limited internal external rotation when flexed. It is the largest joint in the body formed by articulations between the femur, tibia, and patella. Additional soft tissue structures associated with the joint include the menisci, which are pads of cartilage for shock absorption and joint stability. Important ligaments of the knee joint include the anterior cruciate, posterior cruciate, medial collateral, and lateral collateral. The anterior cruciate or ACL runs diagonally within the knee and prevents excessive forward movement of the tibia relative to the femur.
