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.
