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
Figure 1
Performance and strength measures for the index and contralateral legs in patients with hip dysplasia eligible for periacetabular osteotomy (PAO), compared with healthy subjects. Mean values with 95% CIs are presented for single-leg hop distance, Y-Balance Test (YBT) and isometric hip muscle strength. Blue circles represent the index leg (the leg eligible for PAO), teal triangles the contralateral leg and grey squares the healthy subjects.
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 surgery, long-term sports outcomes and registry fidelity has been incomplete or methodologically varied. Addressing these gaps supports better shared …
