Background: The Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow score is a reliable and sensitive tool to measure the performance of overhead athletes. The purpose of this study was to carry out a cross-cultural adaptation and validation of the KJOC questionnaire in Italian and to assess its reliability, validity, and responsiveness. Materials and methods: Ninety professional athletes with a painful shoulder were included in this study and were assigned to the âinjury groupâ (n = 32) or the âoveruse groupâ (n = 58); 65 were managed conservatively and 25 were treated by arthroscopic surgery. To assess the reliability of the KJOC score, patients were asked to fill in the questionnaire at baseline and after 2 weeks. To test the construct validity, KJOC scores were compared to those obtained with the Italian version of the Disabilities of the Arm, Shoulder, and Hand (DASH) scale, and with the DASH sports/performing arts module. To test KJOC score responsiveness, the follow-up KJOC scores of the participants treated conservatively were compared to those of the patients treated by arthroscopic surgery. Results: Statistical analysis demonstrated that the KJOC questionnaire is reliable in terms of the single items and the overall score (ICC 0.95â0.99); that it has high construct validity (rs = â0.697; p < 0.01); and that it is responsive to clinical differences in shoulder function (p < 0.0001). Conclusions: The Italian version of the KJOC Shoulder and Elbow score performed in a similar way to the English version and demonstrated good validity, reliability, and responsiveness after conservative and surgical treatment. Level of evidence: II.
