The Lysholm score: Cross cultural validation and evaluation of psychometric properties of the Spanish version. PLoS One. 2019 Aug 27;14(8):e0221376.http://hdl.handle.net/10668/14449This study aims at assessing the validity and reliability of the Spanish version of the Lysholm score, a widely used instrument for assessing knee function and activity level after ligament injuries. Ninety-five participants (67.4% male, 22±5 years) completed the questionnaire twice within 7 days and a subsample of 42 participants completed a test-retest reliability. Reliability, validity and feasibility psychometric properties were studied. The validity of the questionnaire was analysed using ceiling and floor effects. Factor structure and construct validity were analysed with the SF-36, the Hip and Knee Questionnaire (HKQ) and one leg jump test (OLJT). Criterion validity with the SF-36 Physical State was moderate (r = 0.50 and p The Spanish Lysholm score demonstrated that it is a reliable and valid instrument that can be used to assess knee function after ligament injuries.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/AdultFemaleKnee InjuriesMaleYoung AdultDisability EvaluationFactor Analysis, StatisticalHumansJoint DiseasesKnee JointLigamentsPsychometricsSurveys and Questionnairesresearch article31454386open accessAnálisis factorialArticulación de la rodillaArtropatíasEncuestas y cuestionariosEvaluación de la discapacidadHumanosLigamentosPsicometría10.1371/journal.pone.02213761932-6203PMC6711518https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0221376&type=printablehttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC6711518/pdf
