  3. Exam: Fixed point to fixed point testing
    1. Position
      1. Patient lies supine with legs in neutral position
    2. Measurement (compare both sides)
      1. Anterior superior iliac spine to medial malleolus
    3. Interpretation
      1. Leg Length Discrepancy if difference between sides
  4. Exam: Evaluate tibia and femur lengths
    1. Position
      1. Patient lies supine

    2. Interpretation
      1. One knee higher than other: Tibia longer
      2. One knee projects further anteriorly: femur longer
  5. Management: True Limb Length Discrepancy >1.5 cm
    1. Shoe lift or prosthetic conversion
