Established reconstructive options include tendon transfer, autograft interposition, and allograft interposition, each carrying trade-offs in donor site morbidity, tissue availability, and cost. We describe reconstruction of a chronic insertional TAT rupture in a 68-year-old male using a degradable synthetic polycaprolactone-based polyurethane urea matrix (FlexBand; Artelon, Inc., Marietta, GA, USA) secured to the medial cuneiform with two bone anchors and sutured to a debrided and lengthened proximal tendon stump. At final documented follow-up of 12 weeks, the patient ambulated without foot slap or compensatory gait deviation, with dorsiflexion and plantarflexion clinically symmetric to the contralateral limb and no restriction in activities of daily living.
