Understanding the Tibialis Posterior

At Swan Podiatry and Orthotics, we recognise the critical role of the Tibialis Posterior muscle, often called the ‘tib post,’ in maintaining proper foot function and mobility. This muscle originates on the inside of the shin and extends around the inner ankle, where it attaches to the central point of the foot's arch, essentially providing structural support. The tib post helps maintain the arch, which is vital for walking, running and standing. When this muscle is compromised, it can lead to Tibialis Posterior Tendon Dysfunction (TPTD), often referred to as ‘adult acquired flat foot.’


TPTD occurs when the tib post muscle can no longer support the foot adequately. This condition is most common in adults and is often marked by pain and swelling along the inside of the ankle and foot. While symptoms may start off mild, the arch gradually collapses, leading to the ankle rolling inward. This affects the appearance of the foot and alters gait, often resulting in more complex issues if left untreated. Early recognition and treatment are essential for preventing long-term complications.

Treating Tibialis Posterior Tendon Dysfunction

At Swan Podiatry and Orthotics, we provide a variety of treatment options for Tibialis Posterior Tendon Dysfunction (TPTD) to manage symptoms and help prevent further progression. One of the primary treatments involves custom orthotics. These specialised insoles are designed to redistribute pressure across the foot and provide the necessary support. By compensating for the weakened Tibialis Posterior muscle, orthotics help slow the deterioration of the arch and reduce discomfort.


Along with orthotics, we also recommend targeted exercises to strengthen the Tibialis Posterior muscle. These exercises aim to support the muscle and may slow or even halt the progression of TPTD. In cases where these conservative measures are not enough, more advanced treatments might be needed. These can include physical therapy, bracing or, in severe instances, surgery to correct the structural issues within the foot.


At Swan Podiatry and Orthotics, we are dedicated to providing the latest orthotic solutions within a supportive environment. By working closely with our clients, we aim to restore and maintain foot health. If you’re experiencing symptoms of TPTD, early intervention can make a significant difference in managing the condition and maintaining a pain-free lifestyle.

Frequently Asked Questions

Get in Touch

  • What is posterior tibial tendon dysfunction (PTTD)?

    Posterior tibial tendon dysfunction (PTTD) occurs when the posterior tibial tendon, which supports the arch of the foot, becomes inflamed or damaged. This condition can cause pain and swelling along the inside of the ankle and lead to a fallen arch or flatfoot. Left untreated, it can result in difficulty walking and long-term foot deformity.

  • What are the symptoms of posterior tibial tendon dysfunction?

    Symptoms of PTTD include pain and swelling along the inside of the ankle, especially after physical activity, as well as a visible flattening of the arch. As the condition progresses, the pain may increase, and you may experience difficulty standing on your toes or walking long distances. If you notice these symptoms, it’s important to seek evaluation and treatment early.

  • How is posterior tibial tendon dysfunction treated?

    Treatment for PTTD typically starts with conservative methods such as rest, physical therapy, orthotics and anti-inflammatory medications. Custom orthotics or bracing can provide support and help relieve pressure on the tendon. In more advanced cases or if conservative treatments are ineffective, surgery may be recommended to repair or reconstruct the tendon.

  • Can posterior tibial tendon dysfunction be prevented?

    While not all cases can be prevented, maintaining good foot health is important in reducing your risk of developing PTTD. Wearing supportive footwear, especially during physical activities, and addressing foot and ankle pain early can help. Strengthening exercises for the foot and ankle may also support the tendon and reduce the likelihood of injury. If you’re at risk, regular podiatry check-ups can assist in managing foot health.
