Background: In sporting activities, patellar tendon is commonly subjected to overuse and it influences the athletes' career especially in elite basketball and volleyball players. A condition specific and selfadministrated questionnaire is required for clinical and research purpose to rate disability. The Victorian Institute of Sports Assessment for patellar tendinopathy (VISA-P) questionnaire is widely accepted and a valid tool to assess pain and athletes, suffering from PT, ability to participate in sports. So, the objective of this study is to develop and validate Kannada version of VISA-P questionnaire among Kannada speaking population athletes. Objective: To translate VISA-P questionnaire into Kannada and to study reliability and validity of Kannada version. Methodology: Translation and cross-culture adaptation were performed according to the guidelines followed internationally. Those are: translation, synthesis, back-translation, revision by expert committee, pretesting and appraisal by advisory committee. The psychometric properties were tested by administering the questionnaire to 70 subjects (35 symptomatic and 35 asymptomatic). For test-retest reliability, athletes with patellar tendinopathy were tested twice within a week and test-retest reliability was assessed by Intra-class correlation coefficient (ICC). The validity was tested by comparing the VISA-P-Kannada questionnaire (VISA-P-K) against Blazina classification of patellar tendinopathy (BCPT) using Spearman correlation coefficient. Result: The test-retest reliability was excellent (ICC 0.97). Internal consistency was found to be good (Cronbach's alpha ¼ 0.98). The VISA-PK showed significant correlation by comparing against Blazina and Spearman's score (r ¼ 0.72, p < 0.01). Conclusion:The VISA-P-K translation and adaptation processes were successful. The adapted instrument demonstrated good psychometric properties. The VISA-P-K has proven to be reliable and valid tool and can be used in the Kannada speaking patients with patellar tendinopathy.
