The structural validity of the Danish version of the Oxford Knee Score is not substantiated using Rasch analysis and confirmatory factor analysis
The structural validity of the Danish OKS is inadequate for evaluating patients awaiting TKA or surgically treated with TKA. OKS data should therefore be interpreted with caution. Randomized treatment studies showing no difference in OKS scores may be reanalyzed based on the two domains to reduce the risk of a potential type-2 error.
