Introduction & Objective: The activities of daily living scale of the knee outcome survey are a knee-specific, patient-reported
scale that has been shown to be reliable, valid and responsive to change. The objective of this study was to cross-culturally
adapt the knee outcome survey-activities of daily living scale into Arabic and to assess its psychometric properties (internal
consistency, reliability, validity and responsiveness) in patients with knee disorders.
Method: The cross-cultural adaptation process for the knee outcome survey-activities of daily living scale into Arabic was
performed consistent with the published guidelines. The psychometric properties of this Arabic version were then evaluated.
Participants completed this version three times: At baseline, two to four days later and four weeks later. Correlations between
the Arabic version of Knee outcome survey-activities of daily living scale and the Arabic version of the short form-36 health
survey get up and go and ascending/descending stairs tests were evaluated.
Results: Linguistic and cultural issues were addressed. The Arabic version of the knee outcome survey-activities of daily
living scale demonstrated excellent internal consistency (Cronbachâ??s alpha=0.97) and excellent test-retest reliability (intraclass
correlation coefficient=0.97). Construct validity of the Arabic version of the knee outcome survey-activities of daily living scale
with the Arabic version of short form-36 health survey subscales ranged from r=0.28 to 0.53, (p<0.001). Criterion validity with
the get up and go and ascending/descending stairs tests ranged from r= -0.47 to -0.60 (p<0.01). This Arabic version was able to
detect changes four weeks later (effect size=1.12 and minimum clinically important difference=14 points).
Conclusion: The Arabic version of the Knee outcome survey-activities of daily living scale is a reliable, valid and responsive
measure for assessing knee- related symptoms and functional limitations. This Arabic version can be used in clinical practice
and for research purposes to assess symptoms and functional limitations in Arabic-speaking patients with knee disorders.
