Ideal

• Femoral epicondyles are in same coronal plane
• Axis of the knee joint is in the coronal plane

You See

• Lateral epicondyle is anterior to medial epicondyle on same leg – hip is medially rotated
• Lateral epicondyle is posterior to medial epicondyle on same leg – hip is laterally rotated

Likely Cause

Hip is medially rotated

• Short hip medial rotators (and/or long hip lateral rotators)
• collapsed arch

Leg is laterally rotated

• Short hip lateral rotators (and/or long hip medial rotators)
• Raised medial longitudinal arch
