Description
Summary:This study aims to analyze the safety of a simultaneous bilateral total knee arthroplasty (SBTKA) and to investigate patients' satisfaction with the procedure performed concomitantly.  In a prospective study, we evaluated 45 patients undergoing SBTKA performed by two surgical teams. The mean age of the patients was 66.9 years; 33 subjects were female (73.3%) and 12 (26.6%) were male. We followed a protocol of intra- and postoperatively measures to ensure the safety of this procedure. We evaluated the surgery time and blood loss by hematocrit (Ht) and hemoglobin (Hb) levels on the first postoperative day, the percentage of patients who received a transfusion of packed red blood cells, and the number of required units. We also recorded perioperative complications, and, at the end of 3 months, we asked patients about their preference between the simultaneous or staged procedure.  The mean surgery time was 169 minutes. In the postoperative period, there was an average decrease of 28.2% in Htc and 27.0% in Hgb. A total of 16 patients (35.5%) received a transfusion of packed red blood cells (mean, 1.75 units per patient requiring a transfusion). There were 12 minor complications (26.6%) and 2 major complications (4.4%); furthermore, no patient had a clinical diagnosis of deep vein thrombosis, and there were no deaths.  The SBTKA procedure may be considered safe if performed in selected patients and with a care protocol to prevent complications. This type of procedure was unanimously approved by patients.
