Investigators of this study identified high activity levels and severe hip dysplasia as predictors of younger patient age at presentation for Bernese periacetabular osteotomy to treat symptomatic developmental dysplasia of the hip.
Researchers performed a retrospective review of a multicenter study group and identified 708 Bernese periacetabular osteotomies (PAOs) performed for developmental dysplasia of the hip. Investigators included age at the time of surgery, BMI, history of hip disorder or treatment, and symptom duration in their analysis. Radiographic measurements of the lateral and anterior center-edge angles and acetabular inclination were used to determine the severity of hip dysplasia. Investigators used the University of California, Los Angeles (UCLA) activity score to access activity levels. To determine independent predictors of age at PAO, investigators used multivariable regression analysis with generalized estimating equations.
