Treatment of Infected Total Knee Arthroplasty

Deep infection after total knee arthroplasty (TKA) represents a significant treatment challenge with the possibility of disastrous consequences. The rate of deep infection rate after TKA was reported to be 1.3~2.9% in the past. With the improvements of the operation environment and operative technique and the use of prophylactic antibiotics and antibiotic-mixed bone cement, the rate of deep infection was recently reported to be 0.5~1%. The goal of treatment of a periprosthetic TKA infection is the restoration of a painless, well-functioning joint, with eradication of the infection. Yet the outcome is not always favorable, and the end result could be an arthrodesis, amputation or a pseudoarthrodesis. In some instance, the only realistic option is to suppress the infection with continued oral antibiotics while simultaneously retaining the prosthesis. Two-stage resection arthroplasty remains the standard treatment for chronic periprosthetic infection. Early deep infection may be treated with aggressive debridement and intravenous antibiotics without removal of the implant. Two-stage reimplantation after removal of the implant is most important for the treatment of chronic infection.

Management of the Diabetic Foot Ulcer in Elderly Patients Using the Anterolateral Thigh Perforator Free Flap / 대한족부족관절학회지

PURPOSE: To evaluate the results of anterolateral thigh perforator free flap for reconstruction of foot and ankle in old diabetic patients. MATERIALS AND METHODS: Fifteen diabetic foot ulcer patients over the age of 55 were operated with anterolateral thigh perforator free flap. Hematological, hemodynamic, diabetic, bacteriologic and radiologic tests were checked with examination of blood vessel state in both the donor site and the recipient site. After surgery, serial check-up was performed at 6 week, 6 month, and 1 year postoperatively on the survival of transplantation tissue, condition of foot, and condition of walking. RESULTS: There are one case of transplantation failure and four cases of partial tissue-necrosis. Delayed wound-healing was observed both recipient and donor tissue sites. At the final follow up, three cases of small ulcer were found at junction of flap and recipient tissue in plantar area. Fourteen out of fifteen patients could walk without any brace or walking aids. CONCLUSION: Reconstruction of foot and ankle region in old diabetic patients with the anterolateral thigh perforator free flap is a useful method which can prevent the amputation of foot and ankle
