ABSTRACT
INTRODUCTION
The International Knee Documentation Committee (IKDC) Subjective Knee Form is a valid Patient-Reported Outcome Measure to evaluate ligamentous and meniscal knee injuries. Cross cultural adaptation and validation for the Filipino population should be carried out for the IKDC subjective form due to a change in language, culture and country.
OBJECTIVES
The primary objective of this study was to perform cross- cultural adaptation and determine the clinimetric properties of the Filipino IKDC Subjective Knee Form
METHODS
This was a cross-sectional analytical study that examined the clinimetric properties of the Filipino Version of the IKDC subjective form. A Filipino IKDC subjective form was translated and cross-culturally adapted. The process consisted of a forward translation, backward translation, review of versions by an expert committee, modification of the Draft Filipino version and pre-testing the Initial Filipino version. The clinimetric properties of the “final” Filipino IKDC subjective form, namely face and content validity, construct validity, internal consistency and test-retest reliability were measured from 101 respondents. Face and Content validity were explored with questionnaires, internal consistency was assessed with Cronbach Alpha, test-retest reliability was measured with interclass correlation coefficients and construct validity was analyzed by comparing Filipino IKDC subjective form scores of respondents with injured knees with respondents with healthy knees.
RESULTS
The Filipino version of the IKDC subjective form has internally good clinimetric properties. Content validity showed that all items of the Filipino Version of the IKDC subjective form were perceived to be highly relevant by experts. Face validity showed that the participants graded the questionnaire items as easy understand and relevant to their condition. Internal consistency, test-retest reliability and were interpreted as excellent and acceptable, respectively.
CONCLUSION
The Filipino IKDC subjective knee form is both a valid and reliable PROM to evaluate knee pain and function of Filipino patients with ACL injuries
