Pyogenic knee arthritis in a patient with advanced osteoarthritis is a serious medical problem. We have performed arthroscopic debridement in 136 patients with pyogenic knee arthritis from January 1999 to December 2001. Five of these patients were diabetic, they did not respond to the standard treatment protocol and they continued to have infection. For these patients, we performed open arthrotomy, with implantation of antibiotic cement as a spacer, and staged total knee arthroplasty. The clinical results were evaluated using the Hospital for Special Surgery (HSS) scoring system. At an average follow-up of 38 months (range: 29 to 46), the average pain score was 83 and the functional score was 73 with no patient having recurrence of the infection. This study shows that just as a 2-stage revision is now done for infected total knee arthroplasty, primary uncontrolled infected knees may be treated by a 2-stage arthroplasty as well.
