Area of Science:

  • Orthopedic Surgery
  • Arthroplasty
  • Patient Safety

Background:

  • Simultaneous bilateral total knee arthroplasty (SBTKA) offers potential benefits but requires careful safety evaluation.
  • Assessing patient satisfaction is crucial for procedure adoption.

Purpose of the Study:

  • To analyze the safety of simultaneous bilateral total knee arthroplasty (SBTKA).
  • To investigate patient satisfaction with SBTKA compared to staged procedures.

Main Methods:

  • Prospective evaluation of 45 patients undergoing SBTKA.
  • Monitoring of intraoperative and postoperative measures, including surgery time, blood loss (hematocrit and hemoglobin levels), and transfusion rates.
  • Recording of perioperative complications and patient preference at 3 months.

Main Results:

  • Mean surgery time was 169 minutes.
  • Average decrease in hematocrit and hemoglobin was 28.2% and 27.0%, respectively.
  • 35.5% of patients received packed red blood cell transfusions; 4.4% experienced major complications, with no deaths or deep vein thrombosis cases.

Conclusions:

  • SBTKA can be considered safe in selected patients with a dedicated care protocol.
  • Patients unanimously approved of the simultaneous bilateral total knee arthroplasty procedure.
