Design outcomes

Primary

Measure	Time frame
The evaluation periods were 3 months and 6 months after surgery. The measurement positions were 10degree ankle plantar flexion and 0degree plantar dorsiflexion in the resting standing position. The tibialis anterior tendon, extensor hallucis longus tendon, and extensor hallucis longus tendon were visualized on long-axis images of the talar pulley and tibia using an ultrasound machine. Anterior soft tissue thickness was measured as the shortest distance from the convexity of the talar pulley to the tendon directly above it. The rate of change in anterior ankle soft tissue thickness was determined by dividing the value at 0degree ankle plantar dorsiflexion by the value at 10degree plantar flexion. The average shear modulus (kPa) was calculated using shear-wave elastography.	—
