Outcome after total ankle replacement or ankle arthrodesis in end-stage ankle osteoarthritis on the basis of german-wide data: a retrospective comparative study over 10 years.

Background: In symptomatic end-stage osteoarthritis of the ankle joint, total ankle replacement and ankle arthrodesis are the two primary surgical options for patients for whom conservative treatment fails. Published revision rates are often biased and difficult to compare. In this study, unplanned reoperation rates and revision rates were determined for both surgical interventions based on a large dataset, and risk factors for unplanned reoperations were identified.

[The German Association for Foot and Ankle (D.A.F.) registry on treatment of end-stage total ankle arthritis-what is its clinical impact?].

Initially established as a voluntary prosthesis register for total ankle replacement, the registry now enables analysis of revisions, complications, and clinical and functional outcomes-including patient-reported outcome measures-based on a period spanning more than 10 years. To allow analyses of the outcomes of ankle arthrodesis and supramalleolar osteotomies for treatment of end-stage arthritis in the future, the registry was extended by structured capturing of these procedures in 2018. While descriptive and analytical statistical evaluations of total ankle replacement are already possible today, the number of datasets on arthrodesis and supramalleolar osteotomies is still too small to support these analyses or comparative evaluations.

Analyses of health and health care (hereafter referred to as "health care analyses") usually aim to make transparent the structures, processes, results and interrelationships of health care and to record the degree to which health care systems and their actors have achieved their goals. Health care-related data are an indispensable source of data for many health care analyses. A prerequisite for the examination of a degree of goal achievement is first of all an agreement on those goals that are to be achieved by the system and its substructures, as well as the identification of the determinants of the achievement of the objectives.
