title: [Total knee arthroplasty in the elderly].
abstract: BACKGROUND
  The number of total knee arthroplasties in elderly patients is increasing in accordance with the demographic shift in the population.
  
  
  OBJECTIVE
  Analysis of the special situation in the elderly, conservative treatment options, perioperative risk factors, preoperative preparation, special intraoperative features and outcome.
  
  
  METHODS
  Analysis of currently available scientific data and presentation of own scientific study results.
  
  
  RESULTS
  Total knee arthroplasty in elderly patients is related to an increased perioperative risk of complications. A thorough interdisciplinary preparation is required to reduce risk factors. Ligament stability of the knee does not correlate with age. The postoperative outcome after total knee arthroplasty in elderly patients is decisively influenced by the preoperative function and psychosocial parameters.
  
  
  CONCLUSIONS
  Total knee arthroplasty in elderly patients is particularly challenging for orthopedic surgeons and requires close interdisciplinary cooperation.
