Translation, Cross-cultural Validity and Reliability of a Danish Version of the Anterior Knee Pain Scale (Kujala-DK)
The Anterior Knee Pain Scale (Kujala) is a questionnaire designed to assess adults with patellofemoral disorders and is widely used in both anterior knee pain and patellar dislocation patients.The questionnaire is a patient-reported outcome measure (PROM), that was developed in 1993 and has been translated and validated into most major languages (e.g. French, Italian, Chinese, German, and Spanish) and has gained wide international acceptance. In a recent systematic review, the Kujala was among the eight most commonly used PROMS for patients with patellofemoral pain. In addition, the Kujala was used in almost 80% of studies of patellofemoral instability/dislocation.
The Kujala has been widely used in Denmark during the last 15 years, but surprisingly it has not been translated and validated in Danish according to international guidelines. The translation of the Kujala into Danish will stimulate to more valid and precise results of the Kujala questionnaire in both patients with anterior knee pain and patients with patellar dislocation
The aim of this study is to cross-cultural translate and adapt the Kujala into a Danish Kujala-DK. Secondarily to determine validity and reliability of the Kujala-DK in two consecutive Danish populations of patients with either anterior knee pain or patellar dislocation.
