Overview

In case of severe ankle arthritis, the two common surgical treatments are tibiotalar arthrodesis and total ankle arthroplasty. Few studies have compared these treatments and it remains difficult to determine which operation is the better solution for end stage ankle arthritis. The purpose of the present study is to analyze patient's outcome after each type of ankle surgery and to describe the decision making process.

Outcomes

Primary Outcomes

proportion of reoperations in the total ankle replacement arm and in the tibiotalar arthrodesis arm

Reoperation will be defined as any secondary surgery related to the operated ankle or adjacent joints (subtalar, talonavicular and calcaneocuboid joints), excluding wound healing problems.

Time frame: after 5 years of follow-up

Secondary Outcomes

Proportion of reoperation in the tibiotalar arthrodesis arm and in the total ankle replacement arm

The proportion of reoperation as defined above and for the whole study period in the tibiotalar arthrodesis arm and in the total ankle replacement arm

Time frame: 1, 2, 7 and 10 years

proportion of revision for the whole study period in the tibiotalar arthrodesis arm and in the total ankle replacement arm

For the arthrodesis arm, a revision will be defined as a reoperation for one of the following reasons: nonunion or pseudoarthrosis or malunion. Hardware removal will not be considered as a revision. For the total ankle arthroplasty arm, a revision will be defined as the change of any metallic component of the implanted device. The incidental change of the polyethylene will not be considered as a revision except when it is broken without any

Time frame: 1, 2, 5, 7 and 10 years

The evolution and clinical outcomes

* Pain measured using a Visual Analog Scale (VAS) * Ankle function measured using the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale * Level of activity measured using the University of California, Los Angeles (UCLA) activity scale * Quality of life measured using the EQ5D™ questionnaire * Arthritis status of adjacent joints measured using the Kellgren-Lawrence grading scale * Patient satisfaction

Time frame: 1, 2, 5, 7 and 10 years
