What is Posterior Tibial Tendon Dysfunction?
Posterior Tibial Tendon Dysfunction (PTTD) is a condition that affects the posterior tibial tendon, which runs along the inside of the ankle and foot and connects the calf muscle to the bones on the inner side of the foot. The posterior tibial tendon plays an important role in supporting the arch of the foot and helps to stabilize the ankle.
In PTTD, the tendon becomes inflamed or damaged, leading to a gradual weakening of the tendon and subsequent loss of arch support. This can cause the foot to flatten and the ankle to roll inward, leading to pain, swelling, and difficulty walking.
What causes PTTD?
A foot injury can cause posterior tibial tendon dysfunction. You can hurt this tendon during a fall. This dysfunction can also be caused by overuse. It can happen if you do a lot of walking or running. High impact sports, such as basketball, tennis or soccer can bring it on. PTTD typically develops over time and is often seen in middle-aged or older adults. Risk factors for developing PTTD include obesity, high blood pressure, diabetes, and previous injuries to the foot or ankle.
What are the symptoms of PTTD?
Symptoms include pain on the inner side of your foot. The foot may also swell. It hurts more with activity. It can be hard for you to stand or walk for long periods of time. As your foot becomes unstable, bones may begin to shift. Your heel tilts outward and your arch collapses. This can cause pain on the outer side of your ankle.
Treatment for PTTD depends on the severity of the condition and may include rest, physical therapy, anti-inflammatory medications, and orthotics or bracing to support the foot and ankle. In some cases, surgery may be necessary to repair or reconstruct the damaged tendon.
If left untreated, PTTD can lead to a progressive flattening of the foot, arthritis, and chronic pain. Therefore, it is important to seek medical attention if you suspect you have PTTD symptoms.
