Patients who underwent revision hip arthroplasty experienced more perioperative complications and required more operative time, more blood transfusions and a longer hospital stay compared with patients who underwent revision knee arthroplasty, according to results.
Using the National Surgical Quality Improvement Program database, researchers identified 2,643 patients who underwent revision hip arthroplasty and 2,425 patients who underwent revision knee arthroplasty. Patient-specific factors and surgical variables were extracted for further analysis and researchers recorded the rate and type of postoperative complications and mortality within 30 days of surgery.
Results showed 30-day mortality rates of 1% for revision hip arthroplasty and 0.1% for revision knee arthroplasty. Revision hip arthroplasty patients also had a higher overall complication rate compared with revision knee arthroplasty (7.4% vs. 4.7%), according to results. Researchers found the rate of major (3% vs. 1.6%) and minor complications (5.1% vs. 3.4%) were higher among patients who underwent revision hip arthroplasty. The researchers also noted more blood transfusions (34.4% vs. 1.6%) and longer hospital stays (4.1 vs. 3.4 days) for revision hip arthroplasty compared to revision knee arthroplasty patients. According to results, the strongest modifiable independent predictor for major complications and prolonged hospital stay following revision hip and knee arthroplasties was a low preoperative hematocrit. – by Casey Tingle
