“…Various methods have been used in the initial treatment of periprosthetic knee infection, including irrigation and debridement [10,11,38], direct exchange arthroplasty [6,16], and two-stage revision TKA with subsequent reimplantation [15,18]. Incision and drainage has been an attractive option, with low cost and relatively low morbidity; however, the failure rate has been high, ranging between 61% and 82% [4,5,7,23,30,35,38,39,41,44]. There has also been evidence suggesting that patients who failed a previous incision and drainage procedure were more likely to have a higher rate of failure with a subsequent two-stage revision arthroplasty [46].…”
