ABSTRACT
Deep infection is one of the most devastating complications after knee fractures. It may be related to the initial fracture status or, more commonly, the surgical intervention. From 1991 to 2003, 12 patients underwent knee fusion to treat resistant infection after complex knee fractures or arthrodesis fractures using the Ilizarov method and frame. There were 9 men and 3 women (mean age, 39.7 years). Two-thirds of the patients had long-standing infection and 5 patients had undergone earlier attempts at knee arthrodesis. Correction of concurrent malalignment was achieved in 2 patients. Bone transport using the same arthrodesis frame was necessary in 2 patients to overcome large bony defects. Solid fusion was achieved in all patients by the end of treatment. The average duration of external fixation was 22 weeks (range: 11-44 weeks). No patients required secondary bone grafting to achieve union. Complications occurred in 6 (50%) patients. The most common problem seen was pin tract infection, but only 2 patients required surgical intervention for its treatment. The study emphasizes the clinical success of the Ilizarov method in knee arthrodesis after infected fractures.
