The Dutch version of the Forgotten Joint Score: test-retesting reliability and validation

Acta Orthop Belg. 2016 Mar;82(1):112-8.


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.
