Abstract

Background: This study compared clinical and radiological outcomes of total ankle arthroplasty between rotation- and translation-type varus ankle osteoarthritis.

Methods: Forty-four consecutive patients (≥1-year follow-up) were reviewed and classified by medial gutter apposition (22 per group). Outcomes were assessed preoperatively, at 1-year, and final follow-up.

Results: Visual analogue scale improved from 5.7 to 1.9 in the rotation group and from 5.8 to 0.6 in the translation group; AOFAS hindfoot scores improved from 56.9 to 80.4 and from 51.4 to 92.2, respectively (all P < 0.001). The translation group achieved and maintained correction of talar center migration and hindfoot alignment angle, whereas the rotation group showed deterioration in hindfoot alignment angle between 1-year and final follow-up.

Conclusion: The translation group achieved more favorable clinical outcomes and maintained stable correction of medial talar translation and hindfoot alignment, whereas the rotation group was associated with recurrent hindfoot varus alignment. Subtype-specific recognition may be clinically useful.

Level of evidence: III.

期刊介绍： Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society. The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
