The estimated lifetime risk of symptomatic hip OA is 25% for people who live to age of 85 years 2. As the global life expectancy and the prevalence of obesity is rising, the amount of OA patients will rise in the future 1. Hip osteoarthritis (OA) causes significant morbidity, lowers the quality of life, and creates a considerable socioeconomic burden worldwide. The inter-rater reliability of the US evaluation varies from moderate to excellent, and no association between US and OHS was observed in this patient cohort. On femoral head deformity, performance of the US is superior to CR. US provides similar detection of osteophytes as does CR. For the femoral head deformity, they were 92%, 36%, 38% and 83%, and for the effusion 49%, 85%, 58% and 90%, respectively. Concerning acetabular osteophytes, the respective values were 96%, 0%, 88% and 91%. When THA findings were used as the gold standard, US detected femoral collum osteophytes with 95% sensitivity, 0% specificity, 81% accuracy, and 85% positive predictive value. The pooled inter-rater reliability ( n = 65) varied from moderate to excellent (k = 0.538–0.815). Osteoarthritic US findings were very common, but no association between the US findings and OHS was observed. The diagnostic performance of US and CR was compared by applying the THA findings as the gold standard. OA findings-osteophytes at femoral collum and anterosuperior acetabulum, femoral head deformity and effusion-were assessed on US, CR and THA. Mean patient age was 67.6 years and 38% were males. Sixty-eight hips were included, and intraoperative findings were available on 48 hips. Moreover, the inter-rater reliability of hip US, and association between the US and Oxford Hip Score (OHS) were evaluated. Aim of this study was to assess the US findings of patients with late-stage hip OA undergoing total hip arthroplasty (THA), and to associate the US findings with conventional radiography (CR) and intraoperative findings. ![]()
