Total ankle arthroplasty: four years' experience.

A review of 102 total ankle arthroplasties performed during a four-year period revealed that complications occurred in 41%. 22% with impingement of various types 6.9% with loosening and 2.9% with deep sepsis. The best results were obtained in patients with rheumatoid arthritis and those with posttraumatic osteoarthritis who were older than 60 years of age. Total ankle arthroplasty currently should not be considered in patients with posttraumatic osteoarthritis who are younger than 60 years old. Arthrodesis remains the only acceptable method of treatment in these individuals. Total ankle arthroplasty seems indicated in patients who have significant ankle joint disability secondary to rheumatoid arthritis and in elderly patients with disabling posttraumatic degeneration whose physical demands are limited.
