title: Short term outcomes of revision total knee arthroplasty.
abstract: Few studies have assessed postoperative complications in revision total knee arthroplasty (rTKA). The aim of this study was to assess which preoperative factors are associated with postoperative complications in rTKA. Using the National Surgical Quality Improvement (NSQIP) database, we identified patients undergoing rTKA from 2010 to 2012. Patient demographics, comorbidities, and complications within thirty days of surgery were analyzed. A total of 3421 patients underwent rTKA. After adjusted analysis, dialysis (P = 0.016) was associated with minor complications. Male gender (P = 0.03), older age (P = 0.029), ASA class >2 (P = 0.017), wound class >2 (P < 0.0001), emergency operation (P = 0.038), and pulmonary comorbidity (P = 0.047) were associated with major complications.
