Four\u2009weeks after the procedure, the rats were given an intervention with saline (NS), celecoxib (CE), diclofenac (DF), and tramadol (TM). The rats were executed after 6\u2009weeks of intervention, serum was used to evaluate the levels of inflammation and pain\u2010related factors (IL\u20101\u03b2, IL\u20106, TNF\u2010\u03b1, LPS, CGRP, and NGF), rat joints were used to assess local inflammation in the joints (MyD88) and the effect of the drug on the cartilage (Micro CT, Safranin O\u2013Fast Green stain), Von Frey fibrous filaments were used to assess the sensation of pain in rats, and the differences in feces for the gut microbiome and short\u2010chain fatty acids (SCFAs) were compared by 16S rRNA sequencing and gas chromatographic analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>Rats treated with CE, DF, and TM experienced significant relief from joint pain, but the analgesic effect of CE and DF was significantly weakened after the combined application of antibiotics, while the effect of TM on pain remained after the application of antibiotics.
