What is a common characteristic of acquired adult flatfoot?

A common characteristic of acquired adult flatfoot is the collapse of the medial arch. This condition typically develops over time due to factors such as tendon dysfunction, often involving the posterior tibial tendon, ligament laxity, or other musculoskeletal changes. As the medial arch collapses, the foot becomes flatter and can lead to altered biomechanics, causing various orthopedic issues.

The medial arch is essential for maintaining foot stability and proper load distribution during walking and running. When it collapses, it can result in a variety of symptoms, such as pain and discomfort in the foot, particularly in the area of the arch and the ankle.

Recognizing this characteristic is crucial for understanding the implications of acquired adult flatfoot on overall foot health and the importance of appropriate interventions, including orthotics and supportive footwear.
