At what point in the gait cycle does the knee achieve its greatest amount of flexion?

• A. Pre Swing
• B. Initial Swing
• C. Mid Swing
• D. Terminal Stance

Answer: (B)

During gait, the knee bends most when the leg is halfway through the swing phase. This mid-swing point is when the thigh and the leg are moving forward past the body and the foot must clear the ground, so the knee reaches its maximum bend—typically about 40–60 degrees. This peak in flexion provides sufficient toe clearance for smooth advancement of the limb. Early in swing, the knee is still flexing from initial extension, but it hasn’t reached its maximum yet, and later in swing the knee begins to extend in preparation for heel strike. So the greatest knee flexion occurs in mid-swing.
