Comparison of the Unipolar Electrocautery and the Bipolar Sealer in Reducing Blood Loss in Total Knee Arthroplasty: A Prospective, Randomized, Noninferiority Study.

ABSTRACT:

Background

This was a noninferiority trial to evaluate blood loss during total knee arthroplasty (TKA) when using the unipolar electrocautery system compared to the saline coupled bipolar sealer system in primary TKA.

Methods

One hundred sixty-four patients were randomly assigned by a 1:1 ratio to either the unipolar electrocautery system (N = 82) or bipolar sealer system (N = 82). Inclusion criteria included patients scheduled for primary unilateral TKA, preoperative hemoglobin ≥11 mg/dL, preoperative platelet count ≥150,000, age >18 years, and patient willing to complete all study-related procedures. The primary efficacy outcome was estimated blood loss on morning of postoperative day. Secondary efficacy outcomes were comparison between the preoperative hemoglobin and post
