Joo YB, et al. - In this retrospective review involving 97 patients (mean age was 61 years), researchers identified risk factors affecting the recurrence of septic arthritis of the shoulder after arthroscopic surgery. The following parameters have been considered: age; gender; involved side; presentation of rotator cuff tear; volume of irrigation; bacterial organism involved; preoperative erythrocyte sedimentation rate, C-reactive protein level, and white blood cell count in blood and joint fluid; diabetes mellitus; and hypertension. Investigators found that most patients with native shoulders septic arthritis have been treated effectively with a single arthroscopic irrigation and débridement. The most important factor for preventing the need for additional surgical management can be the amount of irrigation.
