Verified step by step guidance

Understand the anatomy of the knee joint: The knee joint is a complex hinge joint that includes bones, ligaments, tendons, and cartilage. Key components include the femur, tibia, patella, meniscus, and various ligaments.

Learn the function of the meniscus: The meniscus is a C-shaped cartilage located between the femur and tibia. Its primary role is to cushion the knee joint by absorbing shock and distributing weight evenly during movement.

Compare the meniscus to other structures: The patellar tendon connects the patella to the tibia and aids in knee extension. The femoral condyle is part of the femur and contributes to the joint's articulation. The anterior cruciate ligament (ACL) stabilizes the knee by preventing excessive forward movement of the tibia relative to the femur.

Identify the structure responsible for cushioning and stabilizing: While the patellar tendon, femoral condyle, and ACL play important roles in movement and stability, the meniscus is specifically responsible for cushioning and stabilizing the knee joint by reducing friction and absorbing impact.

Conclude that the meniscus is the correct answer: Based on its function and anatomical location, the meniscus is the structure that cushions and stabilizes the knee joint.
