title: Stanmore total knee replacement versus internal fixation for supracondylar fractures of the distal femur in elderly patients.
abstract: BACKGROUND
  Supracondylar fractures of the femur in the elderly are difficult to treat. Total knee replacement is often not considered. The aim of this study was to compare the short to medium term outcome of fixation and total knee replacement in medically fit active elderly patients with no pre-existing arthritis in order to determine whether total knee replacement can be an alternative to internal fixation.
  
  
  METHODS
  In this retrospective study, we included patients who were aged 75 or over with an ASA grade of two or less, walked independently before their injury, and sustained a type A or C supracondylar fracture. Four were treated with internal fixation and six with a cemented Stanmore knee replacement. Patients were reviewed clinically and radiographically a minimum of 6 months after surgery.
  
  
  RESULTS
  The advantages of total knee replacement were a greater proportion of patients returned to independent walking, rehabilitation was more rapid, and knee flexion was better. The advantages of internal fixation were a decreased need of blood transfusion, a smaller proportion of patients reported knee pain at follow up, and a better mean Oxford knee score at follow up. Anaesthetic time and level of patient satisfaction at follow up were similar. There were no peri-operative deaths.
  
  
  CONCLUSIONS
  In this preliminary study, total knee replacement was a reasonable alternative to internal fixation for the treatment of supracondylar fractures of the distal femur in elderly.
