Posterior Tibial Tendonitis is a condition characterized by inflammation and degeneration of the posterior tibial tendon, a major tendons that supports the foot's arch. It attaches the posterior tibialis muscle to the bones inside the foot, primarily for inversion and arch support. When inflamed or damaged, it can lead to adult-acquired flatfoot or posterior tibial tendon dysfunction (PTTD). This condition can develop gradually due to repetitive overuse, excessive strain, trauma, or certain medical conditions. Symptoms include pain, tenderness, swelling, and difficulty walking or bearing weight on the affected foot. In severe cases, the foot may appear flattened and turn outward. Early diagnosis and proper treatment are crucial to prevent further tendon degeneration and potential deformities. Treatment options may include rest, immobilization, physical therapy, orthotics, and in some cases, surgical intervention.
What Causes Posterior Tibial Tendon Dysfunction?
Posterior tibial tendon dysfunction (PTTD) is a condition affecting the posterior tibial tendon, a crucial tendon that supports the foot arch. It is caused by overuse, obesity, aging, biomechanical abnormalities, previous injuries, inflammatory conditions, and diabetes. Overuse can cause the tendon to become inflamed and degenerate over time, especially in athletes and those engaging in high-impact sports. Obesity strains the tendon, increasing the risk of injury and degeneration. Aging makes the tendons more susceptible to injury, especially in individuals over 40. Biomechanical abnormalities, such as flat feet or excessive pronation, can also increase the risk of PTTD. Previous injuries can disrupt the foot's biomechanics, increasing the likelihood of developing PTTD. Inflammatory conditions like rheumatoid arthritis or psoriatic arthritis can weaken the tendon, increasing the risk. Diabetes can also increase the risk due to nerve damage and impaired healing processes.
