title: [Anterior cruciate ligament ruptures and postural control: correlation of functional knee scores with computerized dynamic posturography].
abstract: BACKGROUND
  Quantification of postural stability deficits after anterior cruciate ligament (ACL) rupture requires a complex measurement process, the so-called computerized dynamic posturography (CDP). It would be desirable if the decrease in postural stability caused by ACL rupture could be estimated by simpler functional scores. The aim of this study was therefore to review the currently available standard knee scores for the suitability to assess postural stability.
  
  
  METHODS
  In this study 58 patients with isolated unilateral ACL rupture were examined using CDP. The questionnaires used were Tegner, WOMAC, ADL-KOS, KOS-Sport, KSS and Lysholm scores. The values obtained were compared and correlated with the results of the CDP. In addition, a subgroup analysis of copers and non-copers was performed.
  
  
  RESULTS
  There was no significant correlation with the postural stability deficit for any of the scores examined in this study. Only the subjectively perceived instability correlated appreciably with the CDP with r=0.423.
  
  
  CONCLUSIONS
  All currently used scores for the investigation of patients with ACL rupture cannot give any information about the ability of postural balance. If patients complain about an increased subjective feeling of instability a close observation of postural stability using CDP is inevitable.
