Abstract
METHODS
In a 66-year-old obese woman (WHO stage III, BMI 51 kg/m2) pronounced osteoarthritis of the right knee was diagnosed. Because of progressive chronic pain of the right knee joint her walking distance was limited to a few meters. Conservative therapy was exhausted.
METHODS
Clinical examination showed a restricted and painful range of motion of the right knee and distinctive obeseness on the trunk and the extremities including a lipedema/lymphedema.
METHODS
After a complicated course of treatment lasting for 220 days the total knee replacement ended in an arthrodesis combined with a gastrocnemius muscle flap.
CONCLUSIONS
With respect to this case the high complication-rates in obese patients should be taken into account: Total knee replacement can even lead to loss of the limb in the worst case. In addition to extended preoperative examination this indication should be critically scrutinized.
