Anterior Cruciate Ligament Quality Of Life Questionnaire

Objectives: Despite a number of questionnaires in the area of ACL injuries there is a need for cross-cultural adaptation for patients with ACL reconstruction (ACL-R). To test the measurement properties of the Turkish version of the Anterior Cruciate Ligament Quality of Life Questionnaire (ACL-QOL). Methods: One-hundred nineteen patients with ACL-R completed internal consistency, agreement, construct validity, floor and ceiling effect analyses. Eighty out of 119 patients with ACL-R completed the Turkish adapted version of the ACL-QOL questionnaire twice for the test-retest reliability. A subgroup of thirty-nine patients undergoing physiotherapy were also asked to answer the ACL-QOL questionnaire, the Lysholm knee scale (LKS), Knee Outcome Survey – Activities of Daily Living Scale (KOS-ADLS) and the Short Form-36 (SF-36) at preoperative, 16th week and 2 years post-operatively to assess responsiveness. Results: The questionnaire had high internal consistency (Cronbach α=.95). The paired t-test showed no significant difference between the test-retest means. The intraclass correlation was excellent for reliability and agreement in five domains and overall score (ICC: 0.95, 0.95, 0.97, 0.95, 0.96, and 0.95; p
