Discordance between self-reported and performance-based function among knee osteoarthritis surgical patients: Variations by sex and obesity.

ABSTRACT:

Background

There is currently no standardized method for measuring functional status in knee osteoarthritis (OA) patients, despite that it is one of the top priorities when determining eligibility for total knee arthroplasty (TKA). The purpose of the current investigation was to identify factors associated with discordance between individual self-report and performance-based measures of function for obese and non-obese men and women with knee OA.

Methods

In a cohort of 727 knee OA patients scheduled for TKA, physical function prior to surgery was assessed with the self-reported physical function subscale of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC-pf), and the performance-based Timed Up and Go (TUG).
