Abstract
Background: This study aimed to explore the natural history of distal tibial deformity in varus ankle osteoarthritis and to identify risk factors for its progression.
Methods: This retrospective longitudinal observational study included 97 ankles with moderate to severe varus ankle osteoarthritis, monitored for > 2 years. Radiographic assessments were conducted on weightbearing plain radiographs at the initial and final visit.
Results: Significant tibial anterior surface angle reduction (p = 0.008), talus center medial migration (p = 0.038), and tibial lateral surface angle increase (p = 0.034) occurred. Multiple logistic analysis revealed an association between progression and coronal talar tilt angle at the first visit (odds ratio 1.17, p = 0.015) CONCLUSION: The progression of radiographic distal tibial deformity in varus ankle osteoarthritis was clarified, identifying the coronal talar tilt angle as a risk factor.
Level of evidence: Level IV, retrospective longitudinal observation study.
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.
