Purpose: The purpose of this study is to evaluate the usefulness of a two-stage approach to primary knee arthroplasty with recurrent septic arthritis.
Materials and Methods: We studied 22 patients with recurrent septic arthritis, and we observed them for more than one year of follow-up survey from January 2005 to April 2012 at Yeungnam University Medical Center. The clinical assessment was performed following Knee Society knee score, Knee Society function score, and International Knee Documentation Committee Score (IKDC) subjective assessment. In addition, we analyzed the causative organisms, significant medical comorbidities (diabetes mellitus), period up to primary knee arthroplasty, and radiologic assessment
Results: The average range of postoperative knee motion showed a good result, with an average of 115°. Knee Society knee score improved from 23.5 to 81.0, and Knee Society function score also increased from 22.5 to 73.2. Subjective assessment by IKDC was divided into 15 normal patients and 7 nearly normal patients. No significant difference was observed between patients with causative organisms and those with diabetes mellitus. In the final follow-up survey, recurrence of infection was not reported.
Conclusion: A two-stage approach to primary knee arthroplasty with recurrent septic arthritis is a useful method, because it showed good clinical and radiologic results and favorable subjective assessment.
