Pseudomonas stutzeri knee arthritis in a child: case report and review.

We report a child with Pseudomonas stutzeri-associated right knee arthritis following knife puncture wound. Only four children with P. stutzeri-associated infections have been reported in the English literature in the last 40 years of whom one suffered from calcaneal osteomyelitis caused by this pathogen. In both cases, the suggested mechanism of the infection was local rather than bacterium invasion.
