Infection in tkr
Infection is a serious complication for patients undergoing total knee replacement (TKR) surgery, occurring in 1-2% of cases. The document discusses risk factors for infection, methods for preventing and diagnosing infection after TKR, and various treatment options depending on factors like the organism, extent of infection, remaining bone stock, and soft tissue integrity. Treatment may involve long-term antibiotics, debridement with prosthesis retention, resection arthroplasty, arthrodesis, one- or two-stage reimplantation, or amputation in some cases.
