Infections in total knee arthroplasty are still a major source of morbidity and mortality in Orthopaedics. They often necessitate long term antibiotics, reoperation, and can lead to further complications such as sepsis or even death. Infection prevention remains one of the primary goals of an orthopedic surgeon. While most sources report the infection rate for primary total knee arthroplasty to be less than 1%, the reported rate for infection in revision total knee arthroplasties has been reported to be as high as 5.6%. Despite steps taken towards infection prevention such as proper administration of preoperative antibiotics, strict adherence to sterile methods, and meticulous sterile preparation of the surgical site; infection remains higher in the total knee revision arthroplasty patient population when compared to primary total knee arthroplasty. A dilute betadine lavage (0.35% to 1% povidone iodine) prior to surgical closure has been shown in general surgical procedures as well as orthopaedic spine surgeries to reduce the infection rate in their patients, but this has not been examined in total joint arthroplasty.
