This study aimed to describe the minimal 2\u2010year follow\u2010up after hip arthroscopy for patients with BDDH in the Asian population and use the combination of lateral center edge angle (LCEA) and alpha angles to detect the appearance of impingement in the BDDH population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This retrospective investigation was conducted utilizing information from arthroscopically treated BDDH patients in 2018 and 2019. The following patient\u2010reported outcomes were reported: modified Harris Hip Score, Hip Outcome Score\u2010Activities of Daily Living, International Hip Outcome Tool 12\u2010component form, and Visual Analog Scale. We also considered the clinical data regarding radiological measurements, intraoperative findings, interventions, complications, and subsequent surgical revisions, in the analysis of combination angles in detecting the occurrence of impingement. Patients with asymptomatic contralateral hips from traumatic hip injury (pelvic fracture) served as the control group. A 2:1 propensity score matching was based on age, sex, and BMI. A receiver operating characteristic curve (ROC) was used to identify the thresholds of combination angles and their accuracies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 77 hips met the inclusion and exclusion requirements.

The overall rate of complications was 5.2%, whereas the rate of revisions was 3.9%. Increasing preoperative alpha angle age was significantly positively correlated with improving patient\u2010reported outcomes. The combined angle cut\u2010off was determined to be 80.5\u00b0 (AUC, 0.858; 95% CI: 0.757\u20130.938; sensitivity (SE), 98.1%; specificity (SP), 74.1%; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001) for the occurrence of impingement in BDDH population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Good patient\u2010reported outcomes and low revision rates can be expected in the BDDH population with careful selection of patients in Asian populations.
