Validity was evaluated with multiple methods, including correlations of pre\u2010TKR scale scores and analysis of variance models that used pre\u2010TKR data to compare the relative validity of scales in discriminating between groups differing in assistive walking device use and number of comorbid conditions. Validity was also evaluated by using post\u2010TKR minus pre\u2010TKR change scores to assess relative validity of scales in discriminating between groups rating themselves as better, same, or worse (BSW) in their capability to do activities at 6 months. Responsiveness also was described using effect sizes and standardized response means.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In support of convergent and discriminant validity, KOOS scale scores were worse for patients using an assistive device but only declined weakly with increasing comorbid conditions.

KOOS QOL also had the highest effect size, while SF\u201036 measures had lower effect sizes and standardized response means.
