Total Ankle Arthroplasty

|---|
Since the introduction of the newer generation of total ankle prostheses
for the treatment of ankle arthritis, surgeons have been evaluating their
intermediate-term results and refining their technique. With the substantial
learning curve, experienced surgeons are better able to define clinical pearls
and pitfalls.
Conti presented the intermediate-term results of 120 total ankle
arthroplasties that had been performed with use of the Agility prosthesis
(DePuy, Warsaw,
Indiana)1. Although
patients reported a high degree of satisfaction after an average duration of
follow-up of four years, complications were well defined during this period.
These complications included eight medial malleolar fractures and one lateral
malleolar fracture. The prevalence of component malpositioning was 10%, the
prevalence of postoperative varus positioning of the talar component was 7%,
and the prevalence of syndesmotic nonunion was 3%. Another series demonstrated
a substantial learning curve with a decreasing prevalence of well-defined
complications after total ankle
arthroplasty2. . . . [Full Text of this Article]
