title: Measurement of regional trabecular bone attenuation of the knee following anterior cruciate ligament rupture.
abstract: BACKGROUND
  The purpose of this study was to determine regional trabecular bone attenuation changes of the knee using computed tomography after anterior cruciate ligament rupture.
  
  
  METHODS
  Thirty one patients'-computed tomography images of the injured knees were used to measure trabecular bone attenuation in seven predetermined regions.
  
  
  RESULTS
  Trabecular bone attenuation at four of seven regions (anteromedial area of the proximal tibia, anterolateral area of the proximal tibia, posteromedial area of the proximal tibia, and posterocentral area of the proximal tibia) was negatively correlated with the duration after injury. Independent negative correlation between the duration after injury and the density in anteromedial area of the proximal tibia was detected.
  
  
  CONCLUSIONS
  After anterior cruciate ligament injury, trabecular bone attenuation of the knee decreases by time in certain regions of proximal tibia. Anteromedial region is the most significantly effected of all, which it is the anterior cruciate ligament fixation area.
