abstract
Septic arthritis (SA) is typically managed with antibiotic therapy with or without surgery. Little is known about how patients without surgery differ from their operatively managed counterparts. We compared SA patients who received antibiotic treatment with and without surgery. We conducted a retrospective study of patients with monoarticular septic arthritis admitted to a single tertiary care centre between 1998 and 2015. All 441 monoarticular septic arthritis patients received antibiotics; 382 were also managed operatively and 59 nonoperatively. Nonoperative patients were older (64.4 vs 58.3 years old; p = 0.02) and less likely to have prior joint pathology (44.1% vs 67.5%; p < 0.001). Nonoperative patients presented more often with sepsis (37.3% vs 31.9; p = 0.02) and were more frequently admitted to the intensive care unit (23.7% vs 16.5%; p = 0.04). Nonoperative patients were less often discharged to a rehabilitation facility (37.9% vs 55.8%; p = 0.002) and less frequently readmitted to hospital within 60 days of initial discharge (15.3% vs 18.6%; p = 0.05). However, nonoperative patients were more likely to expire within 30 days after hospital discharge (11.9% vs 3.9%; p = 0.009). Nonoperative patients were sicker at presentation; despite deferral of surgery, they had a relatively high survival rate (88%). Among survivors whose data was available, there were no significant sequelae in post-discharge imaging. These findings support the nonsurgical approach as effective for patients with septic arthritis who are not critically ill at time of presentation.
