All patients with an acute arthritis who underwent a joint aspiration for diagnostic and management purposes were considered for inclusion.

Of the 172 joint aspirations, 90 were positive for crystals (52.33%). Investigated variables associated with increased risk for the presence of bacteria on synovial fluid included features of sepsis (<jats:italic>P<\/jats:italic> &lt; 0.001), joint\u2010restricted range of motion (<jats:italic>P<\/jats:italic> = 0.048), elevated C\u2010reactive protein (<jats:italic>P<\/jats:italic> &lt; 0.001) and elevated total leukocyte count on synovial fluid (<jats:italic>P<\/jats:italic> &lt; 0.001). Of the 24 joint aspirations that were positive for bacteria, 13 had associated positive blood cultures (54.17%). Of the 172 joint aspirations, antibiotics were administered in 96 cases (55.81%). Of these, antibiotics were administered prior to joint aspiration in 41 cases (42.71%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In our study, the most common cause of acute arthritis was crystal arthropathy. An accurate physical examination in conjunction with synovial fluid analysis is of particular importance in diagnosing septic arthritis. Blood cultures are not a reliable substitute for joint aspiration but should nevertheless be undertaken.<\/jats:p><\/jats:sec>","DOI":"10.1111\/imj.13969","type":"journal-article","created":{"date-parts":[[2018,5,14]],"date-time":"2018-05-14T08:05:23Z","timestamp":1526285123000},"page":"1087-1095","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Acute
