title: Postural assessment of patients with non-conventional knee endoprosthesis.
abstract: OBJECTIVE
  To investigate the correlation between the sagittal and frontal alignment and possible postural asymmetries found in patients submitted to total knee stent placement for osteosarcoma.
  
  
  METHODS
  TWENTY TWO INDIVIDUALS WERE DIVIDED INTO TWO GROUPS ACCORDING TO TUMOR LOCATION: femur group (13 patients) and tibia group (nine patients), who were evaluated through postural analysis software (SAPO).
  
  
  RESULTS
  No statistically significant difference was found between groups, supporting previous result showing that both groups present the same postural asymmetries.
  
  
  CONCLUSIONS
  We conclude that both groups have the same postural imbalances, especially the knee of the affected limb that presents hyperextension and center of gravity shifted anteriorly and laterally to the non-affected limb, indicating changes in weight bearing and influencing the gait pattern and balance. Level of Evidence II, Prospective Comparative Study.
