Comments on "Translation, cross-cultural adaptation, validation, and measurement properties of the Spanish version of the anterior cruciate ligament-return to sport after injury (ACL-RSI-Sp) Scale"

Abstract

The purpose of the study was to evaluate the psychometric properties of the survey. While I believe the authors have made a considerable contribution to this work, there are some concerns that I would like to address. Besides, I would like to raise some questions about methodological issues.
