title: Mobility and perceived function after total knee arthroplasty.
abstract: Mobility using the timed up and go (TUG) and perceived pain, stiffness, and physical function (Western Ontario McMaster Universities Osteoarthritis Index) were documented after total knee arthroplasty (TKA). The relationships between mobility and perceived function are limited post-TKA. The first purpose of this study was to determine and compare the TUG test between individuals (n = 11) post-TKA and age-sex-related controls (n = 11). The second purpose of this study was to explore the relationships between mobility and self-reported function post-TKA. The TKA group was 28% (P < .05) slower in completing the TUG compared with controls and reported difficulty in attempting challenging tasks. The TUG was moderately related to the physical function (0.63) dimension of the Western Ontario and McMaster Universities Osteoarthritis Index, as well as the aggregate Western Ontario and McMaster Universities Osteoarthritis Index score (0.59).
