title: Correlation between the Child Health Questionnaire and the International Knee Documentation Committee score in pediatric and adolescent patients with an anterior cruciate ligament tear.
abstract: BACKGROUND
  The modified International Knee Documentation Committee (Pedi-IKDC) Subjective Knee Evaluation Form has recently been shown to be valid, reliable, and responsive in a pediatric and adolescent population. The correlations between the Pedi-IKDC and quality-of-life-related health measures have not been studied in depth to determine how a knee injury affects patients in this age group. The purpose of this study was to examine the association between the Pedi-IKDC score and the Child Health Questionnaire (CHQ) in a group of pediatric patients with an anterior cruciate ligament (ACL) injury.
  
  
  METHODS
  A prospectively collected registry of patients with ACL injuries was searched to indentify all patients who had completed both the Pedi-IKDC and CHQ (CHQ-CF87) questionnaires. These were analyzed to determine significant correlations between domains of the CHQ and the Pedi-IKDC.
  
  
  RESULTS
  A total of 135 patients were included (80 male, 55 female) with a median age of 15.3 years (range, 13.1 to 17.2 y). The cohort included patients treated both operatively (120) and nonoperatively (15). The total Pedi-IKDC score was found to correlate with the majority of the CHQ including expected domains such as physical function (correlation coefficient = 0.64), bodily pain (0.7), and family activities (0.41), in addition to emotional role (0.45), mental health (0.46), self-esteem (0.45), and social limitations--physical (0.38) (P < 0.001 for all correlations).
  
  
  CONCLUSIONS
  Seven of the 12 domains on the CHQ are significantly correlated with the IKDC in adolescent patients with an ACL tear. Self-esteem, mental health, emotional role, and social limitations categories are significantly correlated with knee function suggesting that quality-of-life in this population is affected in domains outside of physical function and pain. A greater understanding of the psychosocial impact of injury may be of utility in these patients.
