Arabic Translation of the Knee Outcome Survey-Sports Activities Scale With Cross-cultural Adaptation and Validation.

Background: There are few sports-specific knee functional scales in the Arabic language. The Knee Outcome Survey-Sports Activities Scale (KOS-SAS) is a validated sports-specific patient-reported outcome measure that assesses knee function in an athletic population.

Purpose: To provide a validated Arabic version of the KOS-SAS (KOS-SAS-Ar) while achieving cross-cultural adaptation for use in an Arabic-speaking population with sports-related knee disorders.
