Inclusion criteria were (1) patients with multiligament knee injury (age, 18-60 years), (2) \u22656 months after injury, and (3) operative or nonoperative treatment. Exclusion criteria were (1) preexisting osteoarthritis or inflammatory arthritis and (2) intracerebral\/spinal cord injury. In phase I of the study, 85 eligible patients were mailed a questionnaire composed of 132 items from 11 existing knee questionnaires. Items were rated with regard to importance and frequency on a 5-point Likert scale. Criteria for inclusion in the first draft of the Multiligament Quality of Life (MLQOL) questionnaire included mean importance rating \u22653.5 and frequency &lt;30% for the response \u201cnever experienced.\u201d In phase II, patient focus groups and expert interviews were conducted until no further new content was generated for the MLQOL, and in phase III, 99 eligible patients across 2 centers were mailed a preliminary MLQOL questionnaire along with the Tegner activity scale, Short Form (SF)\u201336, and anchor questions. Interitem and item-to-total correlations were used to perform item reduction to generate a final MLQOL instrument, which was tested for internal consistency (Cronbach alpha), test-retest reliability (interclass correlation coefficient [ICC]), and construct validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>At the end of phase III, a final MLQOL instrument was developed that was composed of 4 domains (physical impairments [PI], emotional impairments [EI], activity limitations [AL], and societal involvement [SI]) with 52 items in total. The MLQOL had adequate content validity, as none of the domains had any floor or ceiling effects. The Cronbach alpha was .94 (PI), .93 (EI), .94 (AL), and .91 (SI); ICC values were .89 (PI), .86 (EI), .91 (AL), and .88 (SI). Seven of 8 a priori hypotheses were satisfied, indicating good construct validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
