In postural observation, how should the knees align over the feet within the kinetic chain?

• A. Over the big toe
• B. Aligned directly over the 2nd and 3rd toe
• C. Over the ankle
• D. Behind the toes

Answer: (B)

In postural observation, the knee should track in line with the midline of the foot so weight moves through the center of the foot. Aligning the knee directly over the second and third toes places the force through the foot’s central axis, keeping the ankle, knee, and hip in a stable column and supporting proper patellar tracking. This position helps distribute load evenly and reduces excessive valgus or tibial rotation that can occur with poor knee tracking. If the knee sits over the big toe, weight shifts toward the medial edge of the foot, which can promote pronation and inward knee collapse. If it’s only over the ankle, the alignment doesn’t reflect the foot’s base of support and can destabilize the kinetic chain. If the knee ends up behind the toes, the body’s weight sits ahead of the base, increasing the risk of tipping forward. Therefore, the knee should be aligned over the midfoot, near the second and third toes.
