Risk Factors and Microbiological Profile of Knee Periprosthetic Joint Infections with Sinus Tract

A sinus tract is an abnormal channel that communicates between the skin and the joint, and meets one of the major criteria that is diagnostic of periprosthetic joint infection (PJI). The purpose of this study was to compare the risk factors and the microorganism profile of PJI of the knee with an overlying sinus tract to PJI without a sinus tract.
