title: Health-related quality of life in patients with anterior cruciate ligament insufficiency undergoing arthroscopic reconstruction: a practice-based Italian normative group in comorbid-free patients.
abstract: BACKGROUND
  Health-related quality of life (HRQoL) in anterior cruciate ligament (ACL) insufficiency has not been assessed in comorbid-free patients to date. An observational study was therefore conducted on a practice-based sample to test the hypothesis that SF-36 scoring in patients with chronic ACL insufficiency differs from the age- and gender-matched Italian norm.
  
  
  METHODS
  Chronically ACL-insufficient patients with or without meniscal and/or focal chondral lesions were enrolled in the study. Exclusion criteria were acute ACL tear, severe and diffuse chondral lesions, concomitant knee major ligamentous injuries and/or fractures requiring surgery, previous ACL surgery and infectious, neoplastic and inflammatory disease. Knee function was evaluated by International Knee Documentation Committee (IKDC) form, HRQoL with the SF-36 questionnaire, and associated medical comorbidities by a Self-Administered Comorbidity Questionnaire (SCQ).
  
  
  RESULTS
  A total of 316 consecutive patients, 265 males and 51 females (median age 25 years, range 15-52 years) met the inclusion/exclusion criteria. SF-36 norm-based scoring showed that the Physical Functioning, Role Physical, Bodily Pain, and Social Functioning domains were significantly lower than the Italian norm; the Role Emotional domain was also lower than the norm, but the difference was not significant. Conversely, the General Health and Mental Health domains scored significantly higher than the norm; the Vitality domain also exceeded, albeit not significantly, the norm.
  
  
  CONCLUSIONS
  The decision-making process leading to ACL reconstruction currently emphasises the evaluation of knee function and patients' level of activity. The findings in our study, by showing that chronic ACL insufficiency significantly affects HRQoL in otherwise healthy patients, suggest that a multidimensional evaluation including HRQoL in addition to knee function might be integrated into outcome assessment.
