OBJECTIVE: To quantify the differences in physical impairments and in
performance-based measures and patient-reported outcomes in men and women seeking
nonoperative management of symptomatic moderate knee osteoarthritis (OA) and
those with symptomatic end-stage knee OA scheduled for total knee arthroplasty
compared with healthy controls. DESIGN: Cross-sectional analysis of individuals
referred to physical therapy, community participants, and subjects from a 2-year
longitudinal study. SETTING: University research department. PARTICIPANTS:
Cross-sectional analysis of participants (N=289) consisting of a moderate OA
group (n=83), a severe OA group (n=143), and a healthy control group (n=63).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Quadriceps strength, timed
Up and Go test, stair-climbing test, 6-minute walk test, Knee Outcome
Survey-Activities of Daily Living Scale (KOS-ADLS), and Physical Component
Summary (PCS) of the Medical Outcomes Study 36-Item Short-Form Health Survey.
RESULTS: Women had worse scores than men for physical impairment and
performance-based measures (P<.001). In the moderate OA group, women had
significantly lower KOS-ADLS (P=.007) and PCS (P=.026) scores than men, with no
differences seen between sexes in the other 2 groups for patient-reported
measures. CONCLUSIONS: Differences between women and men with knee OA on physical
impairments and performance-based measures are not echoed in the differences seen
in patient-reported measures. These measures signal different domains of knee
function in patients with knee OA and should be used as part of a comprehensive
functional evaluation.
