Simultaneous bilateral total knee arthroplasty offers comparable outcomes to unilateral procedures, with reduced hospital costs and length of stay. This approach also lowers complication risks like phlebitis and pulmonary emboli.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total knee arthroplasty (TKA) is a common procedure for knee osteoarthritis.
  • Simultaneous bilateral TKA (BTKA) and unilateral TKA are surgical options.
  • Comparing the outcomes of these procedures is crucial for patient care.

Purpose of the Study:

  • To statistically compare simultaneous bilateral total knee arthroplasty (BTKA) with unilateral total knee arthroplasty (TKA).
  • To evaluate differences in pain, radiolucency, complications, hospital stay, and costs.

Main Methods:

  • Retrospective review of 132 patients undergoing simultaneous BTKA (264 knees) and 77 patients undergoing unilateral TKA.
  • Both groups received posterior cruciate-retaining condylar prostheses.
  • Statistical analysis of pain, tibial and femoral radiolucency, complications, hospital stay, and costs.

Main Results:

  • No significant differences in pain or femoral radiolucency between simultaneous BTKA and unilateral TKA.
  • Significantly higher tibial radiolucency observed in the unilateral TKA group.
  • Simultaneous BTKA showed no increased risk of postoperative or follow-up complications.
  • Reduced hospital costs (20%) and length of stay (46%) in the simultaneous BTKA group.

Conclusions:

  • Simultaneous bilateral total knee arthroplasty is a safe and effective procedure.
  • BTKA does not increase complication risks and may decrease risks of phlebitis and pulmonary emboli.
  • BTKA offers significant economic and logistical benefits through reduced hospital stay and costs.
