Evaluation of periacetabular osteotomy in patients with hip dysplasia: an investigation of adverse events, functional performance, patient-reported outcomes and radiographic measurements (PhD Academy Award)

What did I do?

My PhD evaluated periacetabular osteotomy (PAO) for symptomatic hip dysplasia across five studies: (1) a systematic review/meta-analysis of PAO benefits and harms;1 (2) a cross-sectional study comparing preoperative functional performance and hip muscle strength with healthy volunteers;2 (3) a cohort study testing whether the Femoral Epiphyseal Acetabular Roof (FEAR) Index predicts patient-reported outcomes;3 (4) a cohort study describing and modelling sports participation up to 20 years after PAO4 and (5) a validation study of the Aarhus PAO database (figure 1) against the Danish National Patient Registry.5

Why did I do it?

Hip dysplasia causes insufficient acetabular coverage, elevated joint loading and pain and is a known risk factor for hip osteoarthritis.6 7 PAO aims to restore coverage and delay degeneration,8 but real-world evidence on adverse events, functional deficits before…
