The purpose of this study was to examine the structural validity of the Oxford Hip Score (OHS) in patients undergoing total hip arthroplasty (THA). This study identified lack of scale validity of the original OHS at the pre-operative visit, indicating that this scale should not be used in its current form in clinical practice. However, subsequent analysis identified a modified short-form version with improved model fit and considered invariant across patients of different sexes and age groups. Prior to its use, further research is warranted in patients undergoing THA.
