Knee Extracapsular Ligaments Patellar Ligament, MCL, & LCL

The video tutorial provides an in-depth look at the knee joint, focusing on extracapsular ligaments such as the patellar ligament, LCL, and MCL. It explains the difference between tendons and ligaments, particularly the patellar ligament and quadriceps tendon. The video also introduces intracapsular ligaments like the PCL and ACL, and discusses the role of menisci in knee stability. It highlights how to differentiate between the LCL and MCL, and examines the posterior view of the knee, including the function of the popliteus muscle.

What defines an extracapsular ligament in the knee joint?

• It is located inside the joint capsule.

• It is part of the synovial membrane.

• It functions outside the joint capsule.

• It connects two muscles.

Which structure is a continuation of the quadriceps tendon?

• LCL

• ACL

• MCL

• Patellar ligament

What is the primary role of the patellar ligament in knee movement?

• Facilitating knee extension

• Facilitating knee flexion

• Stabilizing the lateral meniscus

• Connecting the femur to the tibia

Which ligaments are considered intracapsular in the knee joint?

• PCL and ACL

• Patellar ligament and quadriceps tendon

• Medial and lateral meniscus

• LCL and MCL

How does the meniscus contribute to knee stability?

• By connecting directly to the ACL

• By fusing with the patellar ligament

• By increasing the concavity of the tibial condyle

• By decreasing the concavity of the tibial condyle

What is a key difference between the LCL and MCL?

• MCL is located on the lateral side of the knee.

• LCL does not connect to the lateral meniscus.

• MCL is not connected to any meniscus.

• LCL is connected to the medial meniscus.

Where does the LCL extend from and to?

• From the femur to the quadriceps tendon

• From the lateral epicondyle to the head of the fibula

• From the patella to the tibial tuberosity

• From the medial epicondyle to the medial tibia

What structure prevents the LCL from connecting with the lateral meniscus?

• Medial meniscus

• Popliteus tendon

• Quadriceps tendon

• Patellar ligament

What is the function of the popliteus muscle?

• To lock the knee during extension

• To connect the femur to the tibia

• To unlock the knee during flexion

• To stabilize the patella

Which ligament is in direct contact with the medial meniscus?

• ACL

• LCL

• MCL

• PCL
