Background Prosthetic joint infection is the one of the most difficult complication of total knee
arthroplasty. The incidence of prosthetic joint infection has remained fairly constant over the
past few decades, ranging between 0.7% and 2%, but with an increasing number of arthroplasties
being performed, the number of infected prosthesis will increase. Currently two stage revision is
considered as gold standard treatment for prosthetic knee joint infections. But this exposes
patient to the risk of two operations, requires a prolonged hospital stay and a prolonged period
of immobilization or limited mobilization of the affected joint and also place an enormous
financial burden on the health care sector. Thus single stage revision could be an alternative
option if found equally effective. So the purpose of this study is to evaluate the results of single
stage revision interns of infection control and functional outcome. Patients and methods We
present the results of consecutive series of 12 single-stage revision total knee replacements for
established chronic prosthetic knee joint infection performed since 2012. There were 9 males
and 2 females with mean age of 68 years. Right knee was affected in 6 patients, left in 4 patients
and 1 patient had bilateral involvement. The results were evaluated in terms of infection control,
pre and post operative Oxford knee scores and range of motion in operated knee joint. Results
All eleven patients were available for follow up; mean duration of follow up being 36 months.
Only one patient required revision surgery for recurrent infection, achieving infection control
rate of 91.6%. The Oxford knee scores improved significantly from the mean pre operative value
of 13 to mean post operative scores of 35; P value < 0.05. Conclusion We conclude that, single
stage revision is highly successful and safe in eradicating deep peri-prosthetic knee joint infection
in highly complex cohort of patients, traditionally not deemed suitable for a single stage revision.
