During which phase does the knee reach approximately 60° flexion by the end of the phase?

• A. Mid-swing
• B. Initial swing
• C. Pre-swing
• D. Terminal stance

Answer: (C)

Knee flexion reaches about 60° during the pre-swing phase as the leg transitions from stance to swing. This rapid knee bend helps with toe clearance and prepares the limb for forward progression into the swing. By the end of pre-swing, the knee is typically at or near that 60° mark, whereas in the other phases the knee is either near extension (terminal stance) or still increasing toward but not ending at 60° (early swing and mid-swing).
