When viewing the leg from the front, which set of bony landmarks should line up?

• A. Center of the Patella; Center of the Tibial Tuberosity; Center of the Calcaneus
• B. Just Inside ASIS; Middle of Knee Cap; Center of the Top of Ankle
• C. Center of the Greater Trochanter; Center of the Knee Joint; Center of the Ankle
• D. Just Outside ASIS; Middle of the Knee Cap; Center of the Top of Ankle

Answer: (B)

When you view the leg from the front, you’re looking for a straight vertical line that reflects the leg’s alignment with the pelvis and ankle. The landmarks that line up best are a point just inside the front edge of the pelvis (just inside the ASIS), the center of the knee cap, and the center of the top of the ankle. This combination sits along the body’s midline and gives a clear axis from hip to ankle, helping you assess neutral pelvis position and proper leg alignment during movement. Using a landmark off to the side (like the greater trochanter) or distant to the midline (like the calcaneus or other lateral points) would skew the line and not accurately represent the leg’s frontal alignment.
