Compared with unilateral total knee arthroplasty, patients who underwent simultaneous bilateral total knee arthroplasty experienced an increased risk of overall complications, according to study results.

Using the 2010 to 2012 American College of Surgeons National Surgical Quality Improvement Program, researchers retrospectively identified 973 patients who underwent simultaneous bilateral total knee arthroplasty (TKA) and matched these patients with 3,516 unilateral TKA cases. Researchers recorded patient demographic characteristics, preoperative comorbidities, laboratory data and 30-day perioperative outcomes.

Results showed readmission rates, 30-day mortality and surgical complications, including periprosthetic infection, had no significant differences between matched cohorts. However, researchers found patients who underwent simultaneous bilateral TKA experienced increased overall complications, medical complications and reoperations. Simultaneous bilateral TKA was also associated with a significantly longer hospital stay, according to study results. – by Casey Tingle
