Double Contour Sign

Description

Emphasizing the importance of understanding these measurements, Dr Hiemstra notes that many options focus on the trochlear groove and tilt. However, only one measurement, the double contour sign, cannot be observed in skyline or merchant views. This sign is specifically associated with trochlear dysplasia and is visible in lateral views.
