Causes
There are two main types of surgery to treat flat feet. The most common is reconstructive surgery, which repositions the tendons and fuses certain joints to properly realign the foot. Another procedure uses a subtalar implant to support the arch. The metal implant is put in the back of the foot to correct flat feet.
Symptoms
This retrospective study demonstrates a significant correlation between moderate or severe pes planus and the prevalence of knee and lower back pain. The authors found that "moderate or severe pes planus is associated with nearly double the rate of anterior knee pain and intermittent low back pain".
Prevention
Individuals with pes planus (low arches or flat feet) or pes cavus (high arches) are at increased risk for developing plantar fasciitis. However, overuse rather than anatomy is the most common cause of plantar fasciitis in athletes. Click to see full answer. Consequently, can flat feet cause plantar fasciitis?
Complications
Posterior tibial tendon dysfunction (PTTD) is an important cause of acquired pes planus that frequently observed in adults. Factors that play a role in the development of PTTD such as age-related tendon degeneration, inflammatory arthritis, hypertension, diabetes mellitus, obesity, peritendinous injections and more rarely acute traumatic rupture of the tendon.

Introduction
Classification
Epidemiology
Clinically Relevant Anatomy
Pathophysiology
Characteristics/Clinical Presentation
- The classification of the pes planus is based on two aspects: 1. Arch height: The best parameter to characterize medial longitudinal arch structure was found to be a ratio of navicular height to foot length. It is accepted that the flatness of normal children’s feet and their age are inversely proportioned. 2. Heel eversion angle:Heel eversion or hindfoot valgus is generally accepted as a …
Associated Co-Morbidities
- Roughly 20% to 37% of the population has some degree of pes planus, With most cases being the flexible variety. It is more common in children (about 20-30% of children with some form of flat feet) with most children going on to develop a normal arch by 10 years old. Genetics play a strong role with it typically running in families.
Diagnostic Procedure
- The calcaneus, navicular, talus, first three cuneiforms, and the first three metatarsals make up the medial longitudinal arch. This arch is supported by posterior tibial tendon, plantar calcanea navicular ligament, deltoid ligament, plantar aponeurosis, and flexor hallucis longus and brevismuscles. Dysfunction or injury to any of these structures may cause acquired pes planus. …
Medical Management
- The pathophysiology of pes planus can vary greatly depending on whether it is congenital or acquired, and then whether it is flexible or fixed. In considering developmental flatfoot, the medial longitudinal arch of the foot normally develops by the age of 5 or 6. This occurs as the fat pad in babies is gradually absorbed, balance improves and skilled movements are acquired. In some c…
