title: [Comparison and clinical significance between geometrical characteristics of tibial plateau between Uighur nationality and Han people].
abstract: OBJECTIVE
  To compare the difference and clinical significance of geometrical characteristics of tibial plateau between Uighur nationality and Han people by computed tomography scan and three-dimensional reconstruction.
  
  
  METHODS
  A total of 49 inpatients and outpatients were randomly selected (normal knee without any tibial involvement) and volunteers of Han people and 45 ones of the Uighur nationality at our hospital and cooperative hospitals. Then the subjects were divided into groups according to gender. The following linear geometric parameters of tibial plateau were measured: width of tibial plateau (WTP), width of medial tibial plateau (WMTP), sagittal length of medial tibial plateau (SLMTP), width of lateral tibial plateau (WLTP) and sagittal length of lateral tibial plateau (SLLTP).
  
  
  RESULTS
  (1) Males were greater than females in linear parameters in the same group (P < 0.01); (2) the groups of Uighur nationality were greater than groups of Han people in linear parameters in the same gender (P < 0.05); (3) the gaps between WMTP and WLTP, SLMTP and SLLTP of Uighur nationality were all more approximate than those of Han people (P < 0.05).
  
  
  CONCLUSIONS
  The geometrical characteristics of tibial plateau have some visible discrepancy between Uighur nationality and Chinese Han people. The prosthetic design concept and technology of total knee replacement targeting the Uighur nationality should take into consideration the discrepancy.
