KINE 3135: The Knee Joint (Part 1)

This video tutorial explores the anatomy of the knee joint, focusing on its structure, major ligaments, and the role of the menisci. It discusses the anterior and posterior cruciate ligaments, as well as the medial and lateral collateral ligaments, explaining their functions and how they contribute to knee stability. The tutorial also covers common knee injuries, such as ACL tears, and the impact of different stances on ligament stress. Real-life examples, like Andrew Bynum's torn meniscus, illustrate these concepts. The video concludes with a preview of upcoming content on muscle contractions of the knee joint.

Which bone is primarily responsible for making contact with the femur in the knee joint?

• Patella

• Humerus

• Tibia

• Fibula

What is the primary function of the anterior cruciate ligament (ACL)?

• Prevent posterior displacement

• Prevent medial movement

• Prevent lateral movement

• Prevent excessive rotation

What is the main role of the menisci in the knee joint?

• Connect muscles to bones

• Cushion and stabilize the joint

• Facilitate blood flow

• Transmit nerve signals

Which stance is characterized by knees angled outward, causing the lateral condyles to not align?

• Neutral stance

• Valgus stance

• Normal stance

• Varus stance

What type of stress does the medial collateral ligament (MCL) protect against?

• Valgus stress

• Varus stress

• Posterior stress

• Rotational stress

Which ligament is responsible for preventing the tibia from moving posteriorly with respect to the femur?

• ACL

• MCL

• LCL

• PCL

What is a common cause of ACL injuries in athletes?

• Overuse from running

• Improper footwear

• Direct blow to the knee

• Excessive rotation during sudden stops

Which ligament provides lateral stability to the knee joint?

• MCL

• LCL

• PCL

• ACL

What is the function of the infrapatellar bursa in the knee joint?

• Prevents bone growth

• Supports the menisci

• Lubricates the synovial cavity

• Connects ligaments

Which movement is likely to cause a valgus stress on the knee?

• Knees bent forward

• Knees angled inward

• Knees in neutral position

• Knees angled outward
