- debridement w/o component removal:
- see debridement and washout of infected THR
- IV antibiotic therapy has limited success in treatment of infected TKR; managed with wound debridement, polyethyene exchange,
application of temporary antibiotic beads, and IV antibiotics;
- acute hematogenous infection:
- early acute hematogenous infection occurring around previously secure & well functioning prosthesis;
- Segawa et al: 5/7 hematogenous infection treated successfully with debridement, IV antibiotics, and prosthetic retention;
- Arthroscopic irrigation and debridement of infected total knee arthroplasty: report of two cases.
- Infection After Total Knee Arthroplasty. A Retrospective Study of the Treatment of Eighty-one Infections.
- post operative infection: (see calcium sulfate vance beads)
- post operative infection may be successfully treated w/ ATB and debridement, if delay of treatment is less than 3-4 weeks;
- in chronic infections, infectious process often extends to bone-cement interface, resulting in loosening and resistent infection;
- good outcomes:
- Estes, et al:
- initial débridement with prosthesis retention and placement of antibiotic-impregnated cement beads
- second débridement within 7 days, at which time the beads are removed and new modular parts inserted
- 2 / 20 patients had persistent infection
- no failures in the acute postoperative group (0 of 2) and two of 18 in the acute hematogenous group
- A Two-stage Retention Débridement Protocol for Acute Periprosthetic Joint Infections
- Tintle, et al:
- serial irrigation and debridements, polyethylene exchange when applicable, interval placement and exchange
of tobramycin/vancomycin polymethylmethacrylate beads and 6 weeks of IV antibiotics
- authors noted all infections were eradicated while retaining prosthetic components;
- Prosthesis retention, serial debridement, and antibiotic bead use for the treatment of infection following total joint arthroplasty.
- Is There Still a Role for Irrigation and Debridement With Liner Exchange in Acute Periprosthetic Total Knee Infection?
- intermediate outcomes:
- Success Rates of (I+D) and Prosthesis Retention for Treatment of Acute Deep Prosthetic Infections
- poor outcomes:
- Segawa, et al: 5 out of 10 deep infections which were diagnosed in the acute postoperative period were successfully
- Fehring, et al: 54 of 86 patients (63%) failed;
- Koyonos, et al: infection control was not achieved in 90/136 joints (65%) - staph was risk factor for failure;
- Gardner, et al (2011): 25 / 44 patients (57%) failed ODPE (open debridement and liner exchange);
- Choi, et al: 31% - higher rate of success with non-S. aureus infection and was higher with polyethylene exchange;
- Van Kleunen, et al: salvage was successful in 8/13 joints with deep infection; polymicrobial infections had poor results;
- Marculescu, et al: 2-year survival rate free of treatment failure was 60%
- Hsieh, et al: comparing gram positive post op joint infection, treating gram negative PJI with debridement was associated
with a lower 2-year cumulative probability of success (27% vs. 47%, p= 0.0016);
- Fehring, et al (2013): 63% failure rate;

Gram-negative Prosthetic Joint Infections: Risk Factors and Outcome of Treatment
- relative contra-indications:
- success w/ gm negative infections is dismal and success w/ resistant staph infections is fair to poor;
- management: (see antibiotics)
- with definite infection, procede with open debridement, liner removal, and insertion of antibiotic spacer;
- need for tissue biopsy cultures from the component membrane interface
- remember that in the case of biofilm, there may be minimal infection in joint fluid and capsule, and the main area of
infection will be over the component /bone-membrane interface;
- ref: A microbiological evaluation of 54 patients undergoing revision surgery due to prosthetic joint loosening.
- antibiotic spacer is shaped similar to size and thickness of poly liner (apply when still soft - careful to not trespass into
- rest of available space can be filled with cement
- consider postoperative articular antibiotic infusion
