Is deltoid ligament insufficiency a contraindication to total ankle arthroplasty?
Deltoid ligament insufficiency represents a difficult problem with regard to total ankle arthroplasty. The ankle replacements do not have significant varus-valgus constraint and instead rely on intact or reconstructable ligaments for stability. Because no current reliable deltoid ligament reconstruction procedure is available, the use of an ankle replacement in the face of deltoid ligament insufficiency is not recommended. How do you assess the vascularity of the talar body following fracture in a candidate for a total ankle arthroplasty? Vascularity of the talar body is important in ankle arthroplasty because virtually all of the ankle replacement components are ingrowth prostheses requiring bony ingrowth for stability. Magnetic resonance imaging is the best way to determine if the talus retains enough of its blood supply to perform a successful total ankle arthroplasty. Do patients with coronal plane malalignment of the ankle benefit from total ankle arthroplasty? Patients with coron
