The purpose of the present research was to translate the original English version of International Knee Documentation Committee (IKDC) Subjective Short Form to Persian and to assess validity and reliability of it in Iranian patients with ACL injury.
The Persian version of the IKDC Subjective Short Form was administered to 145 patients including 111 men (76 %) and 34 women (24 %) with the clinical diagnosis of knee ACL tear that were referred to our Knee and Shoulder Center at Mashhad University of Medical Sciences, Mashhad, Iran. The Persian IKDC Subjective Short Form and Persian SF-36 questionnaire were completed by patients in the clinic before beginning any treatment intervention. Patients filled out the Persian IKDC 72 h again before receiving a major treatment; we were then able to use the test-retest method to calculate reliability.
The average age of the subjects was 30.9 ± 10.4 years. The calculated ICC with 95 % confidence interval was 0.845. In this study, Cronbach's alpha was 0.845. There were significant correlations between mean total score of the Persian IKDC and all items of the SF36 (P < 0.05) except for MCS (P = 0.055).
Cronbach's alpha and correlation of IKDC Subjective Short Form and SF-36 demonstrated that the Persian version of IKDC has both strong reliability and validity. The Iranian version of IKDC has favourable validity and reliability and therefore can be used to assess Persian-speaking patients with cruciate ligament injuries.

本研究旨在将国际膝关节文献委员会（IKDC）主观短表的原始英文版本翻译为波斯语，并评估其在伊朗 ACL 损伤患者中的有效性和可靠性。
对 145 例患者（包括 111 名男性[76%]和 34 名女性[24%]）进行了波斯语 IKDC 主观短表评估，这些患者的临床诊断为膝关节 ACL 撕裂，他们被转诊到伊朗马什哈德医科大学的膝关节和肩部中心。患者在开始任何治疗干预前在诊所完成了波斯语 IKDC 主观短表和波斯语 SF-36 问卷。患者在接受主要治疗前 72 小时再次填写了波斯语 IKDC，我们随后能够使用测试-重测法计算可靠性。
受试者的平均年龄为 30.9±10.4 岁。计算的 95%置信区间 ICC 为 0.845。在这项研究中，Cronbach's alpha 为 0.845。波斯语 IKDC 的平均总分与 SF36 的所有项目均呈显著相关（P<0.05），除了 MCS（P=0.055）。
IKDC 主观短表的 Cronbach's alpha 和相关性以及 SF-36 表明，波斯语版 IKDC 具有很强的可靠性和有效性。伊朗版 IKDC 具有良好的有效性和可靠性，因此可用于评估讲波斯语的 ACL 损伤患者。
