Brief Summary

Background: KOOS is a self -administered instrument which assesses the patient's opinion about the Knee associated problems. For now it is available in English \& various other languages \& is a complete instrument in itself. In India it has been translated in Hindi so far. However, each province in this country has a unique language. Maharashtra is the second largest state in India and Marathi is the regional language of the communication. Since KOOS is a self-report measure, its translation in this local language was thought to be necessary. This disease specific measure which is originally designed for English speaking region when employed to non-English population needed to be translated with unique method to achieve a normative equivalence and linguistic validation. Methods: After taking permission from KOOS web manager T1, T2, T12, B1 \& B2 versions were formatted according to the guidelines laid down by AAOS for cross cultural adaptation of health status measure. T12 version was sent for the field testing. Total 32 subjects who met the eligibility criteria were Included in this study. Results: Statistical analysis for reliability with test re-test method suggested Perfect correlation (r =1) between day 1 \& 2. A range of 0.83-0.54 co-relation co-efficient (r) demonstrated the validity of KOOS and its subscales when compared against the 8 different domains of SF-36. All this correlations were statistically highly significant. Sport and recreation subscale had many missing responses since many items in this subscale were not appropriate for the Maharashtrian cultural set-up. Participants additionally provided the information about other functional activities which were difficult to execute due to knee associated pain and disability. Conclusion: Marathi version of KOOS is proved to be a reliable \& valid measure. Future scope: this study demonstrate a need to undertake the cross cultural adaptation since a constant pattern of impairment revealed in the execution of daily activities such as sitting on the floor and attending certain yoga postures etc. Key words: linguistic validation, disease specific self-report, KOOS, Marathi translation, quality of life.
