Background:
This study aimed to investigate the prevalence of radiographic ankle osteoarthritis (AOA) in Japan and identify its risk factors.
Methods:
The analysis included data from the population-based cohort study, radiographs of the knees and ankles, ultrasonography of the ankle to examine chronic ankle instability (CAI), and questionnaires on ankle pain, job history, height, and body weight. A total of 597 individuals aged > 50 years were included in the study. The risk factors for AOA were calculated using multivariate logistic regression analysis.
Results:
The study revealed a 13.9% prevalence of radiographic AOA among the participants, with 1.2% reporting painful AOA. Female sex, aging, history of ankle fractures, and CAI were identified as the risk factors associated with AOA.
Conclusions:
This cross-sectional study highlights the significant prevalence of radiographic AOA in a rural Japanese population, emphasizing the importance of considering ankle fractures and CAI as potential risk factors for AOA development.
Levels Of Evidence:
Level II, prospective cohort study.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
