Tibialis Posterior Tendinopathy

Tibialis posterior tendinopathy is a condition affecting the tibialis posterior tendon, a large tendon that runs along the inside of the ankle and connects the tibialis posterior muscle in the calf to the arch of the foot. This tendon plays a vital role in supporting the arch and allowing the foot to function properly during walking, running, and standing.

PTTD occurs when the tendon is overused or stressed, leading to pain, swelling, and weakness along the inside of the ankle. Repeated strain can cause the tendon to overstretch, resulting in micro-trauma, inflammation, and damage to its structure.
If left untreated, PTTD can cause ankle weakness and a gradual collapse of the arch, affecting the shape and function of the foot. It is the most common cause of Adult Acquired Flat Foot Deformity, where the arch of the foot lowers over time and walking or standing becomes more difficult.

At our clinic, our podiatrists perform a full assessment—including clinical evaluation, with diagnostic imaging available at our ultrasound clinic when necessary—to confirm the diagnosis and develop a tailored, individualised treatment plan. Early intervention can reduce pain, restore function, and help prevent further deformity.
