title: Is there a relation between hip torsion, coverage and osteoarthritis of the knee?
abstract: OBJECTIVE
  Biomechanic factors play a role in the pathogenesis of knee osteoarthritis. The aim of the study was to find out whether there is a relation between femoral, acetabular anteversions, anterior, posterior acetabular coverages and primary osteoarthritis of the knee.
  
  
  METHODS
  Thirty patients with primary osteoarthritis of the knee and 29 control subjects were enrolled into the study. Femoral anteversion, acetabular anteversion, McKibbin's instability index, anterior acetabular sector and posterior acetabular sector angles were measured using tomographic scanograms.
  
  
  RESULTS
  There was no difference between groups for each parameter (P > 0.05).
  
  
  CONCLUSIONS
  This study did not show any relationship between the axial plane changes in the hip joint and primary knee osteoarthritis.
