Verified step by step guidance

1. Understand the anatomy of the femur: The femur is the longest and strongest bone in the human body, located in the thigh. It plays a crucial role in supporting the weight of the body and allowing movement of the leg.
2. Identify the proximal articulation: The femur articulates proximally with the coxal bone (hip bone) at the hip joint. This connection allows for a wide range of motion in the hip.
3. Identify the distal articulation: Distally, the femur articulates with the tibia at the knee joint. This articulation is essential for knee movement and weight-bearing activities.
4. Consider the patella: The femur also articulates with the patella, which is a sesamoid bone located in the knee. The patella protects the knee joint and improves the leverage of the thigh muscles.
5. Clarify the absence of fibula articulation: The fibula does not directly articulate with the femur. It is located laterally to the tibia and primarily serves as an attachment site for muscles rather than directly participating in the knee joint.
