N2 - Background: The Oxford Hip Score is used to evaluate the outcome after total hip arthroplasty. The Oxford Hip Score was developed more than 20 years ago with only some degree of patient involvement. We question if the Oxford Hip Score is still relevant for the present-day total hip artrhoplasty patients. We aimed to determine whether the Oxford Hip Score contains items that are relevant for present-day patients with osteoarthritis undergoing total hip arthroplasty, thus investigating the content validity. Methods: Patients aged 60–75 years, undergoing total hip arthroplasty for primary osteoarthritis were recruited to participate in focus group interviews preoperatively and at 3 and 12 months after primary total hip arthroplasty. We conducted 6 focus group interviews in which 30 patients participated. The interviews were audio-recorded and transcribed verbatim. Using Interpretative Phenomenological Analysis, we inductively organised the interview transcripts into particular items/themes which we then compared to items in the Oxford Hip Score. Results: We identified 6 general items with 41 sub-items. The 6 general items were pain, walking, physical activities, functional abilities, quality of life and psychological health. We found that items in the Oxford Hip Score were all in some way relevant to the patients but that the Oxford Hip Score lacks several important items relevant for present-day total hip artrhoplasty patients, including several physical activities, functional abilities and certain aspects of quality of life and psychological health. Conclusion: We found that the Oxford Hip Score lacks important items for present-day patients in our population. Due to findings regarding several additional items that are not present in the Oxford Hip Score, particularly concerning physical activities and quality of life, we question the content validity of the Oxford Hip Score for a present-day population. Our findings indicate a need for a revision of the Oxford Hip Score.
