    Summary

    Patient satisfaction after periacetabular osteotomy (PAO) is linked to preoperative hip dysplasia severity. Higher preoperative lateral center edge angle (LCEA) correlates with increased satisfaction following PAO surgery.

    Area of Science:

    • Orthopedic surgery
    • Hip joint biomechanics
    • Patient-reported outcomes

    Background:

    • Periacetabular osteotomy (PAO) aims to treat acetabular dysplasia and prevent osteoarthritis progression.
    • Previous studies focused on radiographic and demographic factors, with limited exploration of patient expectations and satisfaction.
    • Understanding factors influencing patient satisfaction is crucial for managing expectations and improving surgical outcomes.

    Purpose of the Study:

    • To investigate the association between preoperative patient demographics, radiographic parameters, and postoperative satisfaction following PAO.
    • To determine if specific radiographic measures correlate with patient satisfaction after PAO surgery.
    • To identify predictors of patient satisfaction in the context of acetabular dysplasia treatment.

    Main Methods:

    • A cohort of 40 patients undergoing PAO between April 2017 and April 2019 completed anonymous satisfaction surveys.
    • Preoperative and postoperative radiographs were analyzed for lateral center edge angle (LCEA) and Tönnis roof angle.
    • Statistical analyses, including Spearman's correlation and logistic regression, were used to assess correlations between satisfaction and radiographic/demographic data.

    Main Results:

    • 75% of patients reported satisfaction with their PAO outcome.
    • No significant association was found between patient age or sex and postoperative satisfaction.
    • A positive correlation was observed between preoperative LCEA and patient satisfaction (r = 0.351, p = 0.027).
    • Each degree increase in preoperative LCEA was associated with a 1.13-fold increase in the odds of postoperative satisfaction.

    Conclusions:

    • Preoperative hip morphology, specifically the lateral center edge angle (LCEA), appears to be associated with patient satisfaction after PAO.
    • Patients with more severe hip dysplasia (lower preoperative LCEA) may experience lower satisfaction rates.
    • These findings suggest that preoperative radiographic parameters hold prognostic value for patient satisfaction and warrant further investigation.
