KNEE ARTHRODESIS AS A FINAL SOLUTION: A RETROSPECTIVE STUDY

Sepsis following total knee replacement (TKR) is a disastrous complication. The knee arthrodesis comes as the final solution to solve the chronic infection after multiple failed surgeries. Our objective was to review these procedures performed in our institution for the past 20 years.We present a retrospective study with 5 cases of severe unsolved knee infection after TKR, who have been finally submitted to knee arthrodesis performed between 1993 and 2008. The patients are 4 males and 1 female, with a mean age of 62 years (ranging from 55 to 74 years) at the time of surgery. They presented MRSA infection (3 cases), P aeruginosa infection (1 case) and Mycobacterium tuberculosis (1 case). The average follow up was 25 months (between 12–48 months). The Visual Analogic Scale (VAS) value was registered.The mean number of surgeries before the arthrodesis was 3,6. In 4 of the 5 cases the surgeon used an external fixator to achieve the fusion. In the other patient, an intramedullary nail was used. The arthrodesis...
