title: Arthroscopic irrigation and debridement of infected total knee arthroplasty: report of two cases.
abstract: Various methods have been described for the treatment of the acutely infected total knee arthroplasty. These include antibiotic suppression, open debridement and irrigation, exchange arthroplasty, resection arthroplasty, arthrodesis, and amputation. A method not frequently reported is arthroscopic irrigation and debridement. Two cases of acutely infected total knee arthroplasty treated with arthroscopic irrigation and debridement are presented. In both cases there was a benign postoperative course averaging five months. Both infections were secondary to hematogenous seeding from a distant focus of infection. The patients presented within approximately 12 h after the onset of knee symptoms and were taken for arthroscopic irrigation and debridement within 12 h after presentation. Gram-positive organisms sensitive to the antibiotics being used were cultured in both. Postoperative knee function and range of motion returned rapidly and disability was minimal. At average 30-month follow-up both patients were pain free, had full activity of daily living, and had no clinical or radiographic evidence of infection. Arthroscopic irrigation and debridement appears to be an effective method of treatment in select cases of infected total knee arthroplasty.
