The purpose of our study is to identify complications and early functional outcome scores in patients treated with periacetabular osteotomy (PAO) for mild acetabular dysplasia.
The study population consisted of patients from a single centre prospective hip registry undergoing PAO with mild acetabular dysplasia (LCEA ≥18° and ≤25°; n = 27 patients; Mild Dysplasia group). A comparison group of patients undergoing PAO with more severe acetabular dysplasia (lateral centre-edge angle [LCEA] ≤17°; n = 50 patients; Severe Dysplasia group) were included as a comparison cohort. Demographics, radiographic findings, complications, and functional outcome scores were recorded at 6 months, 1 year, and 2 years postoperatively (mean 15 months [range 6-30]).
Demographic characteristics were similar in patients with mild dysplasia undergoing PAO compared with more severe dysplasia. Achievement of radiological correction and complication rates were not different between the 2 groups. Functional outcome scores showed similar improvements in modified Harris Hip Score (mHHS), hip outcome score (HOS) activities of daily living (ADL), HOS Sport, and the international Hip Outcome Tool-33 (iHOT-33) at all time points between the 2 groups with over 90% of patients in the mild dysplasia group achieving a minimum important change (MIC) in functional outcome scores at final follow-up.
Patients with symptomatic mild acetabular dysplasia undergoing PAO have similar complication rates and functional outcomes as a cohort of patients with more severe dysplasia.
