There were eight knee arthrodesis in infected total knee arthroplasties between January, 2006 and July, 2008. The mean age was 66,3 years old (63-80), three patients were male and five female. The method of choice was external fixation with semi rings and the mean follow up was 21 months (12 - 40 months). This is a multicentric prospective study with patients answering the Nottingham Health Profile, an objective questionnaire which evaluates quality of life. We observed an improvement of 49% in the levels of preoperatory quality of life compared to postoperatively, as well as 100% of radiographic union. These are facts that confirm the safe use of this technique to the treatment of infected total knee arthroplasty. Level of Evidence IV, Case series.
