Abstract

Background

This study retrospectively evaluated a consecutive series of patients who underwent Total Ankle Replacement (TAR) with the third-generation mobile bearing Hintegra® prosthesis performed by a single non-designer surgeon. Few studies reporting outcomes from total ankle replacement (TAR) have been published by non-designer investigators. Clinical outcomes, complication and satisfaction rates have also been analysed.

Method

A consecutive series of 52 patients that received 55 TAR were reviewed between 2008 and 2016. Kaplan-Meier survival analysis was performed on all of the 55 TAR. Change in AOFAS hind foot scores from pre to post surgery and self-reported satisfaction scores were analysed.

Results

The 10 year survival analysis group had a minimal mean follow up of 10 years (SD 1.5, median 8.5, min 7.0. max 12.9), with a survival rate of 87 % (CI 0.74 to 0.94). Five-year survival rate was 93 % (CI 0.82 to 0.97). Six ankles (11 %) had to be revised. One having a talar component revision with polyethylene exchange and the remaining five with a conversion to arthrodesis. Only thirty-eight of the original 55 TAR were analysed for outcome measures. Seventeen patients were lost to follow up and 19 patients were deceased. In total 79 % (30) patients were satisfied with the TAR procedure with sixteen patients reporting to be extremely satisfied. Sixteen per cent (6) patients reported to be neutral and only 5 % (2) patients stated that they were not satisfied with the TAR procedure.

Conclusions

Our results show that the Hintegra® TAR prosthesis leads to good medium to long term survivorship and acceptable patient satisfaction rates. The results of these cases, all treated by a single non-designer surgeon in a low-volume practice, demonstrate that acceptable outcomes may be achieved outside of high-volume TAR centres.

Level of evidence

期刊介绍： Journal of Clinical Orthopaedics and Trauma (JCOT) aims to provide its readers with the latest clinical and basic research, and informed opinions that shape today''s orthopedic practice, thereby providing an opportunity to practice evidence-based medicine. With contributions from leading clinicians and researchers around the world, we aim to be the premier journal providing an international perspective advancing knowledge of the musculoskeletal system. JCOT publishes content of value to both general orthopedic practitioners and specialists on all aspects of musculoskeletal research, diagnoses, and treatment. We accept following types of articles: • Original articles focusing on current clinical issues. • Review articles with learning value for professionals as well as students. • Research articles providing the latest in basic biological or engineering research on musculoskeletal diseases. • Regular columns by experts discussing issues affecting the field of orthopedics. • "Symposia" devoted to a single topic offering the general reader an overview of a field, but providing the specialist current in-depth information. • Video of any orthopedic surgery which is innovative and adds to present concepts. • Articles emphasizing or demonstrating a new clinical sign in the art of patient examination is also considered for publication. Contributions from anywhere in the world are welcome and considered on their merits.
