摘　　要：BACKGROUND A fracture of the acetabulum is an uncommon,but serious injury.Established outcome tools do not reflect the patient’s perspective after fracture of the hip joint.Originally designed for post-arthroplasty patients,the Forgotten Joint Score(FJS)is a patient-reported outcome measurement(PROM)tool evaluating the diseasespecific health-related quality of life(HR-QoL).AIM To validate the FJS in patients after acetabular fracture.METHODS In a prospective mono-centric cohort study,we evaluated 100 patients at mean 5.2±3.6 years after a fracture of the acetabulum.The validation study followed the complete COSMIN checklist protocol.For calculation of convergent validity,we used the Tegner-Activity Scale,the Western Ontario and McMaster Universities Osteoarthritis Index,the EuroQol-5D,and a subjective rating of change as an anchor variable.RESULTS We confirmed good internal consistency with a Cronbach‘s alpha of 0.95.With an intraclass correlation coefficient of 0.99(95%CI:0.97,0.99),test-retest reliability of the FJS was excellent.Correlation coefficients between the questionnaires were moderate to high ranging from|0.56|to|0.83|(absolute value).No relevant floor or ceiling effects occurred.Standard error of measurement was 3.2 and smallest detectable change(SDC)was 8.8.Thus,changes greater than 8.8 points between two assessments denote a real change in FJS.CONCLUSION The FJS is a valid and reliable tool for evaluation of patient-reported outcome in posttraumatic condition after acetabular fracture.The SDC indicating a real clinical improvement was 8.8 points in the FJS.We could confirm responsiveness of the FJS and found no relevant floor-or ceiling effects.
