Researchers also assessed percentage changes from baseline to days 7, 3 and 1 prediagnosis, the day of PJI diagnosis and days 1, 3 and 7 postdiagnosis.<\/p>\n<p>According to Cushner, patients had a meaningful decline in step count, walking speed and range of motion before diagnosis of deep infection, while patients who were taking antibiotics had a significant decline in step count.<\/p>\n<p>\u201cOne of the things about arthroplasty infections is the earlier you catch it, the better it gets,\u201d Cushner told Healio. \u201cIf you catch it late, then everything has to come out and we can debate whether to do a one-stage or two-stage, but still it is a big operation. If you catch it early then the [debridement, antibiotics and implant retention (DAIR)] procedure is much more effective. These were markers to detect infection early that we picked up by examining a dataset.\u201d<\/p>\n<h2>For more information:<\/h2>\n<p>      <b>Fred D.
