Question

A collateral ligament of the knee is located:

A. on the posterolateral surface of the joint
B. on the lateral or medial sides of the joint
C. on the anterior or posterior sides of the joint
D. crisscrossed through the middle of the joint

Answer 1

The collateral ligament of the knee is located on the lateral or medial sides of the joint, with the fibular collateral ligament on the lateral side and the tibial collateral ligament on the medial side.

Step-by-step explanation:

The collateral ligament of the knee is located on the lateral or medial sides of the joint. Specifically, the knee has two main collateral ligaments:

• The fibular collateral ligament (lateral collateral ligament), which is located on the lateral side of the knee.
• The tibial collateral ligament (medial collateral ligament), found on the medial side.

The fibular collateral ligament spans from the lateral epicondyle of the femur to the head of the fibula, while the tibial collateral ligament runs from the medial epicondyle of the femur to the medial tibia. The tibial collateral ligament is also attached to the medial meniscus, indicating its importance in knee stability. In the fully extended position of the knee, both collateral ligaments become taut, providing stabilization and preventing undue side-to-side or rotational motions.
