Adjustments in 2011 KSS increase the clinical suitability / Remco N. Dinjens in Acta Orthopaedica Belgica, Vol.82/1 (March 2016)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol.82/1 (March 2016) . - p. 43-51 Titre : Adjustments in 2011 KSS increase the clinical suitability Type de document : texte imprimé Auteurs : Remco N. Dinjens ; Bernd Grimm ; Ide C. Heyligers ; Rachel Senden Année de publication : 2016 Article en page(s) : p. 43-51 Langues : Anglais (eng) Résumé : The 2011 KSS is a valid clinical TKA questionnaire, but with a low completion rate (42%). Adjustments, focusing on optimizing scale features, are required to improve its clinical use. The low completion rates, non-optimal scale features, lacking rules or a combination of these factors where addressed, leading to the development of the adjusted 2011 KSS (2011 KSSA). Four-hundred-ninety-nine primary TKA patients were addressed pre- and postoperative by mail. Clinimetric quality was evaluated. Seventy percent responded and 90% completed the scale. Internal consistency proved excellent with Cronbach’s Alpha = 0.79 for all subscales. Strong correlations were found between the Functional Activity subscales and KOOS-PS (r = -0.63 to -0.87). All subscales improved significantly after intervention (r-range 14-33%, effect size 0.50-2.85). Postoperatively, ceiling effects were found in the subscales Symptoms (16%) and Walking & Standing (26%). Adjustments led to a shortened and simplified questionnaire while maintaining its clinimetric quality.
