1. Break Down the Problem

To determine which movements are allowed at the knee, we need to analyze each option provided in the context of knee anatomy and physiology.

2. Relevant Concepts

The knee is primarily a hinge joint, allowing for specific movements. The relevant movements to consider include:

• Flexion: Bending of the knee, decreasing the angle between the thigh and the lower leg.
• Extension: Straightening of the knee, increasing the angle between the thigh and the lower leg.
• Abduction and Adduction: These movements occur mostly at ball-and-socket joints and are not significant at the knee.
• Elevation: This term usually refers to movement vertically and is not applicable to the knee joint specifically.

3. Analysis and Detail

Let's analyze the movements:

1. Flexion: Allowed at the knee when the leg is bent.
2. Extension: Allowed at the knee when the leg is straightened.
3. Abduction: Not a movement of the knee; it pertains to moving a limb away from the midline.
4. Adduction: Not a movement of the knee; it involves moving a limb toward the midline.
5. Elevation: Not applicable to the knee joint.

4. Verify and Summarize

Flexion and extension are the only two movements permitted at the knee joint, while abduction, adduction, and elevation do not apply.

Final Answer

The movements allowed at the knee are:

• Flexion
• Extension
