Artroplastia total de tobillo : serie de casos del Hospital Metropolitano período 2009 - 2019

Abstract

Ankle arthroplasty is a surgical procedure developed due to the need for better pain management, mobility, and improvement of daily activities in patients as an alternative for ankle arthrodesis. In 1970, the beginning and development of the technique took place in France by Lord and Marotte. However, due to the type of articulation, and the demanding biomechanics, the technique showed complications and poor results according to reports at the time of its invention.

The development of second-generation implants showed similar or worse results until 1980 when third-generation ankle implants resurfaced with the idea of using a mobile bearing between two resurfacing pieces of the talus and tibia. With Buechel and Pappas in the U.S. and Kofoed in Denmark as promoters of the Scandinavian Total Ankle Replacement (STAR) prosthesis, the current series are more encouraging with an 89% survival rate after 10-years of use.

Currently, Ankle arthroplasty is considered essential for well-selected patients due to its high risk of failure, having ankle arthrodesis as backup. In this study, we show the improvement of clinical symptoms by referring to the AOFAS scale, weighing the risks found in literacy.
