This study examined the psychometric properties of the Korean version of the Patient Knowledge Questionnaire-Osteoarthritis (PKQ-OA-K). A cross-sectional survey was conducted with 157 adults with osteoarthritis from the outpatient clinic at a university hospital in Korea. The overall correct answer rate for the PKQ-OA-K was 60.4%; notably, the drug therapy subscale had the lowest median score percentage (42.9%). For structural validity, exploratory factor analysis identified the PKQ-OA-K as two-dimensional, explaining 52.4% of the total variance. Confirmatory factor analysis showed that the two-factor model adequately fit the data. The PKQ-OA-K was positively correlated with education level (r = 0.24) and osteoarthritis outcomes (r = 0.17), thus verifying the hypotheses of construct validity. The intraclass correlation coefficient for test-retest reliability was 0.52; alpha was 0.44. The PKQ-OA-K has excellent validity but imperfect reliability for adults with osteoarthritis. This study recommends cautious use of the PKQ-OA-K to assess Korean patients' knowledge of osteoarthritis.
