The Posterior Tibial Tendon and Flat Foot: A Clinical Connection
The human foot is a marvel of biomechanical engineering, designed to withstand significant forces while providing mobility and stability. Central to its intricate structure and function is the posterior tibial tendon (PTT). This vital tendon plays a critical role in supporting the medial longitudinal arch of the foot, acting as a primary dynamic stabilizer. When the PTT becomes dysfunctional, a cascade of events can lead to the progressive collapse of the arch, a condition commonly known as acquired adult flat foot deformity.
