Adult Acquired Flatfoot – Tibialis Posterior Tendon Dysfunction


Flatfoot is a common problem in both children and adults. However in adults the problem is usually caused by a tendon.

The Tibialis Posterior muscle is the deepest muscle in the calf complex. It plays a major role in the stability of the foot and in holding the arch up.

The tendon of this muscle travels down the leg behind the medial malleolus (Ankle bone), as it travels under the foot it has an area that is prone to injury.

The tendon can become injured in a variety of ways. These can vary from: increased work/training load, running/walking distance, weight gain/loss, age, footwear, flat feet, and other chronic health issues.

Tibialis Posterior Tendon Dysfunction is a progressive condition that continues to deteriorate without intervention. Pain usually starts as either: foot pain when you first get out of bed, aching of the heel and arch after exercise, cramping or aching to the inside ankle, and sometimes can be burning through the foot and ankle.

The end stage of this results in a permanent flat foot deformity. This cannot be corrected without surgical intervention.

Early assessment and treatment by a Podiatrist is important to prevent permanent deformity in the foot.

Treatment can vary depending on the stage of tendon damage and deformity to the foot. Treatment may involve some of the following: Strapping, Dry Needling, Low level laser, Kinesiology tapping, Soft tissue release, Muscle strengthening, Gait retraining, Orthotics, Footwear advice, Footwear modification, Ankle braces.
