title: Changes in self-reported knee function and health-related quality of life after knee injury in female athletes.
abstract: OBJECTIVE
  To document the changes in self-reported health-related quality of life and knee function in a cohort of young female athletes who have sustained a knee injury.
  
  
  METHODS
  Prospective cohort.
  
  
  METHODS
  An outpatient sports medicine clinic and university student health service.
  
  
  METHODS
  A convenience sample of 255 females (age = 17.4 ± 2.4 years) who injured their knee participating in sport or recreational activities. Injuries were categorized as anterior cruciate ligament tears, anterior knee pain, patellar instability, meniscus tear, collateral ligament sprain, and other.
  
  
  METHODS
  Knee function was assessed with the 2000 International Knee Documentation Committee (IKDC) knee survey. Health-related quality of life was assessed with the SF-12 version 2.0 (acute) survey (SF-12).
  
  
  METHODS
  Dependent variables included the paired differences in the 2000 IKDC and SF-12 subscales, and composite scores from preinjury to diagnosis. Paired differences were assessed with paired t tests (P < 0.05) reported as the mean ± SD.
  
  
  RESULTS
  International Knee Documentation Committee scores at diagnosis were significantly lower than preinjury scores (P < 0.001). SF-12 scores were lower (P < 0.001) at diagnosis for each subscale (physical functioning, role physical, bodily pain, general health, vitality, social function, role emotional, and mental health) as well as the physical and mental composite scores.
  
  
  CONCLUSIONS
  In addition to negatively affecting knee function, sport medicine providers should be aware that knee injuries can negatively impact the health-related quality of life in these athletes immediately after injury.
