Gout After Total Knee Arthroplasty

Abstract

Crystalline arthropathies are well-known pathologies in a native knee; however, the literature is scarce with regards to crystalline arthropathies in a total knee arthroplasty (TKA). The presentation of crystalline arthropathy in a TKA can be similar to a periprosthetic joint infection (PJI), making it difficult to distinguish between the 2 diagnoses. We present 1 case highlighting the similarity between crystalline arthropathy and PJI. A 71-year-old man with a history of bilateral TKAs presented with bilateral painful knee effusions and was initially presumed to have PJIs; however, he was later diagnosed with gout and successfully treated medically. A complete review of the literature demonstrates that crystalline arthropathies after TKA are infrequently reported and can be difficult to decipher from PJIs, and there is a lack of standardized treatment.

Acute haematogenous periprosthetic joint infection due toStreptococcus sanguinisalong with coexistent crystalline arthropathy after total knee arthroplasty: a rare combination

“…CIA, which could be caused by gout after joint arthroplasty, is a rare but described phenomenon 8–10. CIA combined with a bacterial superinfection is even rarer with only four cases described in literature 8–10…”

“…Other options are non-steroidal anti-inflammatory drugs. Surgical treatment is not described as a viable option in cases of CIA 8–10…”
