E.5 End points |
E.5.1 | Primary end point(s) |
The degree of postoperative pain, assessed with the pain subscales of the Knee injury and Osteoarthritis Outcome Score (KOOS) or the Hip disability and Osteoarthritis Outcome Score (HOOS). |
De mate van postoperatieve pijn, bepaalde met de pijn subschalen van de "Knee injury and Osteoarthritis Outcome Score (KOOS) of de "Hip disability and Osteoarthritis Outcome Score" (HOOS). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
6 months after THA/TKA |
6 maanden na THA/TKA |
|
E.5.2 | Secondary end point(s) |
Pain
Secondary endpoints that will be used to asses the change of perceived pain are the Visual Analogue Scale (VAS) and the pain subscales of the KOOS/HOOS. Neuropathic pain will be assessed by means of the modified-painDETECT (m-PDQ) questionnaire (knee m-PDQ, hip m-PDQ).
Sensitisation/sensitivity measurements (QST)
A multimodel assessment of pain responses will be performed to assess characteristics associated with neuropathic pain and/or (central) sensitization. Two QST-measurements will be assessed, namely; Mechanical Temporal Summation (MTS) and Blunt Pressure Pain Thresholds (PPT).
Function and physical activity
Change of function will be assessed by means of the following KOOS/HOOS subscales: symptoms, ADL and sport/recreation. Change of physical activity will be assessed by means of the International Physical Activity Questionnaire (IPAQ)
Quality of life and satisfaction
Change of quality of life will be assessed by means of the QOL subscale of the KOOS/HOOS and the SF-36 questionnaire. Patients perceived level of expectation at the time on the waiting list (in relation to postoperative outcomes) will be assed by means of the Hospital for Special Surgery Knee Replacement Expectations survey (HSSKR) and with the Hospital for Special Surgery Hip Replacement Expectations survey (HSSHR). Furthermore, the Patient Global Impression of Improvement (PGI-I) scale will be obtained to measure a change in the level of satisfaction.
Depression and anxiety
Change in depression and anxiety will be assessed by means of the Hospital Anxiety and Depression Scale (HADS).
Pain catastrophizing
Pain catastrophizing will be assessed by means of the pain catastrophizing questionnaire (PCS).

Pijn
Secundaire eindpunten die gebruikt zullen worden om de ervaren pijnverandering te objectiveren zijn de “Visual Analogue Scale” (VAS), sensitisati en de pijnsubschalen van de KOOS/HOOS. Neuropatische pijn zal worden bepaald door middel van de gemodificeerde-painDETECT (m-PDQ) vragenlijst (knie m-PDQ, heup m-PDQ)
Sensitisatie/gevoeligheid
Twee QST-methoden zullen worden gebruikt om de eigenschappen welke geassocieerd worden met neuropatische pijn en/of (centrale) sensitisatie te objectiveren, namelijk; Mechanical Temporal Summation (MTS) en Blunt Pressure Pain Thresholds (PPT).
Functie en fysieke activiteit
Verandering in functie zal worden geobjectiveerd door middel van de volgende KOOS/HOOS subschalen: symptomen, ADL en sport/recreatie. Verandering van fysieke activiteit zal worden gemeten met de “International Physical Activity Questionnaire”(IPAQ)
Kwaliteit van leven en tevredenheid
Verandering in kwaliteit van leven zal worden bepaald door middel van de “QOL” subschaal van de KOOS/HOOS en de SF-36 vragenlijst. De ervaren mate van verwachting (in relatie tot de postoperatieve uitkomsten) zal worden bepaald middels de “Hospital for Special Surgery Knee Replacement Expectations survey” (HSSKR) of met de “Hospital for Special Surgery Hip Replacement Expectations survey” (HSSHR). Verder zal de “Patient Global Impression of Improvement” (PGI-I) schaal worden afgenomen om een verandering in de ervaren tevredenheid te objectiveren.
Depressie en angst
Verandering in depressie en angst zal worden bepaald middels de “Hospital Anxiety and Depression Scale” (HADS).
Pijn catastroferen
Pijn catastroferen zal worden bepaald middels de "pain catastrophizing questionnaire" (PCS).
