Abstract: Although results of staged reimplantation for septic total knee arthroplasty (TKA) are well-known, the outcomes of a subsequent repeat infection are not well studied. We studied 34 patients (35 TKA), who were treated for reinfection after prior staged reimplantation for septic TKA.
Successful outcome was defined an infection-free prosthetic joint at the time of the last follow-up or death. At a mean follow-up of 59.2 (24-168) months, success was achieved in 24 (68.6%) of 35 knees. Among the failures were 5 amputations, 2 arthrodeses, 1 resection arthroplasty, and 3 continued antibiotic cement spacers. Failure was significantly (P = .02) related to growth of resistant microorganisms.
Success was achieved significantly more often (P = .002) with complete prosthetic removal and reimplantation rather than debridement and retention of component(s). Reinfection after prior reimplantation for septic TKA is challenging but success is possible, although less frequent as compared to first time infection after a primary TKA.
