Introduction:
Achromobacter xylosoxidans is an uncommon opportunistic organism, mainly causing infection in immune-compromised hosts. A. xylosoxidans is a non-fermenting Gram-negative bacillus. Being closely associated with Alcaligenes species was also called A. xylosoxidans.
Case Report:
A few cases of periprosthetic infection by A. xylosoxidans have been reported outside India. A periprosthetic infection with A. xylosoxidans following a total knee arthroplasty is reported in a female.
Conclusion:
A. xylosoxidans is a pathogen capable of causing prosthetic joint infection even in immunocompetent patients. Thorough debridement and appropriate antibiotic treatment is essential for the success of revision surgery.
