A total of 493 patients (493 hips) were included in the analysis. For imaging evaluation, the following parameters of the contralateral (unfractured) hip were measured: LCEA, T\u00f6nnis angle, Sharp's angle, femoral head eminence index (FHEI), and femoral head lateralization. Categorical variables were expressed as numbers and percentages. Continuous variables were presented as mean\u2009\u00b1\u2009SD if normally distributed; otherwise, they were reported as median (Q1, Q3). The Pearson chi\u2010square test, likelihood ratio chi\u2010square test, or Fisher's exact test was used to compare categorical variables.

Patients with DDH and BDDH were at a higher risk of developing mild OA compared to individuals with normal acetabular coverage. However, not all individuals with DDH or BDDH develop OA. Only the T\u00f6nnis angle was significantly associated with mild OA, indicating a 7.8% increase in OA risk for each 1\u00b0 increase in the T\u00f6nnis angle.
