Prosthetic joint infection is a devastating complication following total knee arthroplasty with an incidence of up to 1-2% and high mortality rates. A 2-stage revision arthroplasty is currently considered the gold standard treatment for prosthetic joint infections. Recent studies have shown early promising results with the use of a single-stage explantation and insertion of a prosthetic and/or articulating cement spacer as definitive treatment for prosthetic joint infections in patients who may not be fit to undergo a 2-stage revision arthroplasty. This study aims to evaluate the short-term outcomes in patients who underwent the above procedure.
A retrospective review of 5 patients who underwent the above procedure was performed.
All 5 patients remain infection-free up to the point of follow-up. 4 patients have no complaints of knee pain while 1 patient complains of mild pain with a VAS score of 3-4. 3 patients are able to ambulate with aids while 2 remain wheelchair bound.
This study shows good early outcomes for patients who underwent a 1-stage explantation of the primary total knee arthroplasty components and insertion of an articulating cement spacer as definitive treatment for prosthetic joint infection of the knee.
