In loading response, the external moment at the knee tends to move the knee in which direction?

In loading response, the external moment at the knee tends to move the knee in which direction?

• A. Abduction
• B. Flexion
• C. Internal rotation
• D. Extension

Answer: (B)

In loading response, the leg must absorb the impact of weight transfer, so the external forces acting on the knee tend to bend it. This creates an external knee flexion moment, pushing the knee into a modest flexion as part of shock absorption. To prevent collapse and control the motion, muscles on the front of the thigh generate an opposing internal extension moment. So, the external influence during loading response tends to move the knee into flexion.
