Correlation Analysis of Clinical Outcomes for Patients With Coronal Pelvic Obliquity After Total Hip Arthroplasty in Direct Anterior Approach

DAA-THA in supine position not only significantly improves the hip function of patients with infrapelvic obliquity, but also corrects pelvic obliquity and leg length discrepancy, while maintaining stable acetabular components. For patients with infrapelvic obliquity, in which the pelvis is oblique on the affected side and the angle is more than 3°, the degree of functional improvement and correction is the greatest.
