Understanding Posterior Tibial Tendon Dysfunction (PTTD): Causes, Symptoms, and Treatment

Posterior Tibial Tendon Dysfunction (PTTD) is a common foot problem that can cause significant discomfort and limitations in mobility. Our Podiatrists at New Horizons Foot and Ankle Associates in Louisville, KY take the time to educate patients about this condition to ensure timely diagnosis and appropriate treatment. Let's delve into what PTTD entails, its causes, symptoms, and available treatment options.

What is PTTD? 

The posterior tibial tendon is a crucial structure that supports the arch of the foot and stabilizes the ankle. PTTD, also known as adult-acquired flatfoot deformity, occurs when this tendon becomes inflamed, weakened, or torn, leading to a collapse of the arch.

Causes of PTTD: 

Several factors contribute to the development of PTTD, including:

• Overuse or repetitive strain on the tendon due to activities like running or walking.
• Injury to the tendon from trauma or sudden twisting of the foot.
• Age-related degeneration of the tendon.
• Certain medical conditions like obesity, diabetes, or hypertension can increase the risk of PTTD.
• Structural abnormalities in the foot, such as a high arch or tight calf muscles, can predispose individuals to PTTD.

Symptoms of PTTD: 

• PTTD typically presents with the following signs and symptoms:
• Pain and swelling along the inner side of the ankle.
• Progressive flattening of the arch, leading to a flatfoot deformity.
• Difficulty walking or standing for long periods.
• Pain and fatigue in the foot and ankle, especially with activity.
• Overpronation, where the foot rolls inward excessively during walking.

Diagnosis: 

Diagnosing PTTD involves a thorough physical examination and may include imaging tests like X-rays or MRI scans to assess the severity of tendon damage and any associated structural abnormalities.

Treatment Options: 

The treatment approach for PTTD depends on the severity of the condition and may include:

• Rest, ice, compression, and elevation (RICE therapy) to alleviate pain and inflammation.
• Orthotic devices, such as arch supports or custom-made shoe inserts, to provide support and correct foot alignment.
• Physical therapy exercises to strengthen the muscles surrounding the affected tendon and improve stability.
• Immobilization with a walking boot or cast to allow the tendon to heal in severe cases.Nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroid injections to reduce pain and inflammation.
• In advanced cases or when conservative measures fail, surgery may be necessary to repair or reconstruct the damaged tendon and restore foot function.

Prevention: 

While not all cases of PTTD can be prevented, certain measures can help reduce the risk:

• Maintain a healthy weight to alleviate excess stress on the feet and ankles.
• Wear supportive footwear with good arch support and cushioning.
• Gradually increase the intensity and duration of physical activities to avoid overuse injuries.
• Perform stretching exercises regularly to maintain flexibility in the calf muscles and Achilles tendon.
  

In conclusion, PTTD is a debilitating condition that requires prompt intervention to prevent long-term complications. Our Podiatrists at New Horizons Foot and Ankle Associates in Louisville, KY find that it's essential to educate patients about the causes, symptoms, and treatment options available for PTTD to ensure optimal foot health and mobility. Early recognition and appropriate management can significantly improve outcomes and quality of life for individuals affected by this condition.
