Treatment of chronic, two-plane instability of the ankle joint: syndesmoplasty versus periosteal flap versus tenodesis.
Repair of chronic ankle instability is recommended by a step-to-step approach. Anatomic repair with ligamentoplasty or periosteal flap will result in complete range of motion of the foot, but with less stability (7.1 degrees talar tilt). The more unphysiologic tenodesis procedure should be done in long-standing cases and gross instability, with the risk of loss of motion (10 degrees supination in one third of the cases), but with the advantage of best mechanical stability (3.5 degrees talar tilt).
