N2 - To compare the soft-tissue elasticity between the medial, lateral, and posterior aspects, the deltoid and calcaneofibular ligaments, and the medial, lateral, and posterior capsular tissues were collected from 27 feet of 16 congenital-clubfoot patients. The tissue sound speed, which closely correlates to the Young's modulus, was measured using a scanning acoustic microscope. Contrary to our expectations, lateral ligament showed a significantly higher sound speed than medial ligament (P=0.0023). Lateral capsule also showed a higher sound speed than the medial one (P=0.0338). The results of the study indicated that the lateral soft tissues including the ligaments and capsule underwent severe contracture in congenital clubfoot.
