Abstract

Our study aimed at developing clinical thresholds (cut-off scores) for the Western Ontario and McMaster Universities (WOMAC) osteoarthritis index, EQ-5D and Knee Society Score for discriminating between patients with and without treatment success following total knee arthroplasty (TKA). We performed a retrospective analysis of 1055 patients 2 months after TKA and 765 patients 1 year after TKA. We considered treatment successful if the patient reported high levels of satisfaction and pain relief, functional increase, and a willingness to undergo the same procedure again. Based on this criterion we identified cut-off scores that will facilitate interpretation of the WOMAC, the EQ-5D and the KSS in TKA patients.
