Hip dysplasia is a significant public health issue, representing the single largest cause for total hip arthroplasty in young adults. To gain insight into patient concerns and the impact of hip dysplasia on young adults, we developed a patient-centred outcome measure, the 'Quality of Life Impact and Concerns' (QoLI&C) measure. This short report provides additional evidence on test-retest reliability and suggests refinements to the measure to enhance its research and clinical utility.
Keywords: acetabular dysplasia; developmental dysplasia of the hip; paediatric hip conditions; psychometric validation; test–retest reliability.
