How are limitations in hip rotation compensated?

• A. Inward turning of the feet
• B. Loss of neutral spine positioning
• C. Excessive outward movement of knees (beyond width of feet)
• D. Inward knee valgus

Answer: (C)

When hip rotation is limited, the body substitutes movement from the hip by allowing the knee segment to move more than normal. This outward knee movement, where the knees splay beyond the width of the feet, lets the leg complete the movement without requiring the hip to rotate as much as it normally would. In practical terms, the hip stays relatively constrained, while the knee joint takes on a larger abduction/rotation role to keep the movement going. This pattern shifts stress toward the knee and lower leg rather than the hip, which is why you might see the knees track outward in tasks like squats or lunges when hip rotation is restricted. Strengthening the hip externally rotating muscles and improving ankle mobility can help restore proper alignment and reduce this compensatory knee motion.
