Résumé : |
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 SurveyActivities 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 and pcs scores than men with no differences seen between sexes other 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. |
