[Ankle arthrodesis versus ankle replacement: a comparison].
Ankle arthrodesis is performed for the treatment of unstable, arthritic, painful, and deformed ankle joints. A wide variety of surgical options and approaches exist to treat the difficult problem of an ankle arthrodesis. In patients with only minor ankle deformity and minor bone loss arthroscopically assisted fusion is the treatment of choice. The risk for the development of a pseudarthrosis depends on clinical factors like corticoid medication, nicotine, incorrect alignment and improper mobilization. With adequate shoes the patients can remain asymptomatic for long time. Adjacent joints may show radiological degenerative changes in the long-term follow-up; however, they do not need to be clinically symptomatic. Nowadays total ankle replacement is a valid alternative. The surgical technique is demanding. Implants of the 1st and 2nd generation did not show satisfying results. The newer 3rd generation total ankle arthroplasties show promising medium-term and long-term results.
