A Retrospective Analysis of Hemostatic Techniques in Primary Total Knee Arthroplasty: Traditional Electrocautery, Bipolar Sealer, and Argon Beam Coagulation.
In this retrospective cohort study of 280 primary total knee arthroplasties, clinical outcomes relevant to hemostasis were compared by electrocautery type: traditional electrocautery (TE), bipolar sealer (BS), and argon beam coagulation (ABC). Age, sex, and preoperative diagnosis were not significantly different among the TE, BS, and ABC cohorts. The 3 hemostasis systems were statistically equivalent with respect to estimated blood loss. Wound drainage during the first 48 hours after surgery was equivalent between the BS and ABC cohorts but less for the TE cohort. Transfusion requirements were not significantly different among the cohorts. The 3 hemostasis systems were statistically equivalent with respect to mean change in hemoglobin level during the early postoperative period (levels were measured on postoperative day 1 and on discharge). As BS and ABC are clinically equivalent to TE, their increased cost may not be justified.
