VISA-P score for patellar tendinopathy in males: adaptation to Italian

PURPOSE: To translate and adapt the English VISA-P questionnaire to Italian and to perform reliability and validity evaluations of the Italian VISA-P version in patients with patellar tendinopathy. METHODS: The VISA-P English version was translated into Italian by a bilingual orthopaedic surgeon. The back translation of the Italian version into English was performed by another bilingual orthopaedic surgeon. The original version was compared with the back translation. The VISA-P-I questionnaire was then administered to 25 male athletes (average age 27.9, range 18-32 years) with a diagnosis of patellar tendinopathy. For test-retest evaluation, the 25 patients were asked to complete the questionnaire at first examination, and 30 minutes following the end of this examination. RESULTS: The kappa statistics for 25 patients was 0.78. There were no significant differences between the scores immediately after the consultation and 30 minutes later. CONCLUSIONS: Italian and the English versions of the VISA-P questionnaire evaluate the same aspects of clinical severity in patients with patellar tendinopathy.
