Translation and validation of the Dutch Tegner score and the Lysholm score

The Tegner score and Lysholm score are used worldwide to determine one's function and participation in sports after anterior cruciate ligament surgery. Currently, these questionnaires are not officially translated and validated in Dutch. However, the scores are frequently used in Dutch and different versions are circulating. To allow comparison of results between different studies and prevent the use of multiple versions in the future, a clear translation and validation required. Because of this reason, we are going to officially translated these questionnaires into Dutch and validated them for the Dutch population.
