Candida prosthetic joint infection (PJI) is a rare complication of total knee arthroplasty (TKA). The literature regarding its diagnosis and management is scarce.
We present the case of a 79-year-old woman with history of TKA and femoral intramedullary nailing, who developed PJI caused by Candida lusitaniae. A two-stage exchange arthroplasty was performed. She underwent implant removal, debridement and placement of temporary antibiotic impregnated spacer. Postoperatively, the patient received treatment with micafungin for 24 weeks. Eleven months after the first stage, the spacer was removed and a new knee prosthesis was placed. Complete eradication of infection was demonstrated by negative culture of cement spacer, synovial fluid and periprosthetic tissue. Histology of surgical samples was unremarkable. Empiric treatment with micafungin was given for 6 weeks after placement of the new prosthesis. At 6-month follow-up, there was no evidence of recurrent infection.
To our knowledge, this is the first reported case of Candida lusitaniae PJI.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 August 2018.
All research outputs
#20,530,891
of 23,100,534 outputs
Outputs from Acta Clinica Belgica
#338
of 448 outputs
Outputs of similar age
#291,244
of 334,232 outputs
Outputs of similar age from Acta Clinica Belgica
#5
of 9 outputs
Altmetric has tracked 23,100,534 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 448 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 334,232 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
