Verified step by step guidance

Step 1: Begin by understanding the anatomy of the knee joint. The knee joint is a hinge joint that connects the femur (thigh bone) to the tibia (shin bone) and includes several ligaments for stability.

Step 2: Focus on the abbreviations ACL and PCL. ACL stands for Anterior Cruciate Ligament, and PCL stands for Posterior Cruciate Ligament. Both are key ligaments in the knee joint that cross each other, forming an 'X' shape.

Step 3: Clarify the term 'Cruciate.' The word 'Cruciate' comes from the Latin word 'crux,' meaning 'cross.' This describes the crossing pattern of the ACL and PCL within the knee joint.

Step 4: Compare the other options provided in the question. 'Collateral' refers to the collateral ligaments (MCL and LCL), which are located on the sides of the knee. 'Cartilage' refers to the smooth tissue that covers the ends of bones in joints, and 'Capsule' refers to the fibrous tissue surrounding the joint.

Step 5: Conclude that the correct answer is 'Cruciate,' as it specifically describes the crossing nature of the ACL and PCL ligaments in the knee joint.
