Transcultural validation and adaptation of the Pedi-IKDC scale for the functional assessment of children that undergo knee surgery.

INTRODUCTION

In the last decades sports practice in children has increased, thus increasing the number of musculoskeletal injuries. There are no validated scales in Spanish for the functional evaluation of knee aspects in children. The validation and cross-cultural adaptation of the Pedi-IKDC scale to Spanish, used for this purpose, was carried out.

METHODOLOGY

The scale was applied to 50 patients that suffered traumatic knee injuries between 2016 and 2021 and underwent surgical interventions. The validation process of the scale was carried out after a pilot test, cross-cultural adaptation of words into Spanish, translation-retranslation, statistical, determination of internal consistency of the instrument, intraclass correlation, test-retest and evaluation of data dispersion.

RESULTS

The internal consistency of the evaluated instrument is good according to the Gregory scale with a Cronbach's alpha of 0.82 The intraclass correlation was considered substantial (0.624) and the test-retest correlation, showed a coefficient of 0.91. The Bland-Altman graph showed a low dispersion among the data.

CONCLUSION

The Pedi-IKDC scale can be a useful tool to assess functionality in children who have undergone knee surgery, it is considered valid, with adequate reliability and with the advantage of easy application.
