Reliability, Validity, and Responsiveness of the Lysholm Knee Score and Tegner Activity Scale for Patients with Meniscal Injury of the Knee

Abstract

Overall, the Lysholm knee score and the Tegner activity scale demonstrated acceptable psychometric performances as outcome measures for patients with a meniscal injury of the knee. Some domains of the Lysholm score showed suboptimal performance, and the Tegner scale had only a moderate effect size. Psychometric testing of other condition-specific knee instruments for patients with a meniscal lesion of the knee would be helpful to allow comparison of the properties of the various knee instruments.
