Verified step by step guidance

Understand the anatomy of the knee joint: The knee joint is stabilized by various ligaments, which can be classified as intracapsular (inside the joint capsule) or extracapsular (outside the joint capsule).

Review the extracapsular ligaments: These are ligaments located outside the joint capsule and include the fibular (lateral) collateral ligament and the tibial (medial) collateral ligament. Their primary function is to provide lateral and medial stability to the knee joint.

Differentiate between extracapsular and intracapsular ligaments: The anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) are intracapsular ligaments because they are located within the joint capsule and cross each other to stabilize the knee during movement.

Analyze the transverse ligament: The transverse ligament is not considered an extracapsular ligament of the knee. It connects the anterior horns of the menisci and is located within the joint capsule.

Conclude that the fibular (lateral) collateral ligament is the correct answer: It is an extracapsular ligament that stabilizes the knee joint by preventing excessive lateral movement.
