Acceptance, reliability and validity of the Arabic version of lysholm knee score

Abstract EN

Objectives: To generate a cross culturally adapted translation of the lysholm knee score and to assess its acceptability, reliability and validity as a patient reported outcome measure for Jordanian patients with anterior cruciate ligament (ACL) injuries.

Methods: The score was translated according to established guidelines to Jordanian Arabic and the psychometric analysis was prospectively conducted on a cohort of 73 patients with anterior cruciate ligament (ACL) injury recruited from the orthopaedic sports clinic in Prince Hashim bin Alhussein hospital during the period between March and August 2015.

The translated score was assessed for internal consistency, test retest reproducibility within 14 days, face validity and floor and ceiling effects to assess content validity.

Results: The translated score was acceptable and easy to use.

It showed adequate reliability (Cronbach's alpha=0.60) and good to excellent reproducibility (Intraclass correlation coefficient =0.85).

No floor or ceiling effects were observed and the translated score showed good face validity.

Conclusion: The translated version of lysholm score to Jordanian Arabic is an acceptable, valid and reliable tool to assess Jordanian patients with ACL injuries.
