Abstract

To compare complications following arthroscopy and arthrotomy for treatment of septic knee arthritis. Patients undergoing arthroscopy and arthrotomy for a diagnosis of septic knee arthritis were identified in National Surgical Quality Improvement Program and placed in a multivariate analysis to determine if type of surgery contributed to postoperative complications. Knee arthrotomy was associated with an increased risk for increased operative time [Parameter estimate 4.555 (95% CI:3.023-6.085); p < 0.0001], minor morbid events [OR 2.064 (95% CI: 1.447-2.943); p < 0.0001], and any morbidity [OR 2.285 (95% CI:1.527-3.419); p < 0.0001]. Knee arthrotomy was associated with a higher risk of complications.
