The patients were assigned to 2 groups according to the presence of advanced OA at the last follow-up. Binary logistic regression was used to model the correlation between risk factors and OA. Functional outcomes were assessed using the Foot and Ankle Outcome Score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The data of 332 patients who met the inclusion criteria were included in the analysis. The overall rate of posttraumatic arthritis was 27.7% (nonarthritis group: 240 patients, arthritis group: 92 patients). The arthritic change was significantly affected by BMI (95% confidence interval [CI] 1.29-19.76; adjusted odds ratio [OR] \u2265 30, 6.56), fracture-dislocation injury (CI 1.66-11.57; adjusted OR, 4.06), posterior malleolus (PM) fracture (CI 1.92-12.73, adjusted OR &gt; 25% of the articular surface, 5.72), and postoperative articular incongruence (CI 1.52-18.10; adjusted OR, 7.21).
