Abstract

The aim of this study was to translate the Forgotten Joint Score (FJS) into the Dutch language. This Questionnaire was tested for internal consistency (Cronbach's alpha) and test-retest reliability (intraclass correlation coefficients (ICC)). 159 patients were included in this study ; 74 with a total hip arthroplasty (THA) and 85 with a total knee arthroplasty (TKA). The FJS showed a high internal consistency (Cronbach's alpha = 0.957 ; ICC = 0.943). The FJS showed a significant correlation (r = 0.751) with the WOMAC and low ceiling effects (3.1%). This study proved the Dutch FJS to be highly discriminative in patients treated with a THA or TKA. This makes the FJS a reliable patient related outcome measurement, measuring a new dimension in arthroplasty : the ability to forget an artificial joint in everyday life.
