Introduction: The high Activity Arthroplasty Score ( hAAS) has been designed to differentiate in the functional ability between normal and more active patients after total knee arthroplasty (TKA) and total hip arthroplasty (T hA). no such questionnaire is currently available in the Dutch language. The objective of this study was to evaluate the Dutch version of the hAAS in ThA and TKA patients. Patients & Methods: The forward and backward translated Dutch version of the hAAS combined with the national Dutch patient reported outcome measures (PR oMS) were sent to two hundred patients of all ages who underwent TKA or T hA. The internal consistency, construct validity and ceiling/floor effects of the hAAS were evaluated. Results: 108 patients (51 ThA and 57 TKA) participated in this study. A good internal consistency with a Cronbach’s alpha of 0.78, 0.81 and 0.84 was found in all patients, the Th A and the TKA group respectively. Significant positive correla- tions were observed between the hAAS and VAS Qo l, EQ-5D, all K oo S sub-scores except the symptoms score, and all hoo S sub-scores except the Qo l score. A negative correlation was found with the VAS pain. no ceiling or floor effect was seen in the hAAS. Discussion: The Dutch version of the hAAS can be used to evaluate the functional ability in more active patients of all ages who underwent ThA or TKA with an acceptable internal consistency and construct validity, with no ceiling or floor effects.
