Background:
Postoperative anemia is frequent after revision of total knee ar-
throplasty (TKA) with reported transfusion rates up to 83 %. Despite increased
efforts of reducing blood loss and enhancing fast recovery within the fast-track
setup, a considerable transfusion rate is still evident.
Purpose / Aim of Study:
The aim of this study was therefore to evaluate the
effect of a bipolar sealer on blood loss and transfusion in revision TKA.
Materials and Methods:
In this single-center prospective cohort study with
retrospective controls, 51 patients were enrolled in a fast-track setup for revi-
sion TKA without the use of a tourniquet. Twenty-five prospectively enrolled
patients received treatment with both a bipolar sealer and electrocautery,
whereas 26 patients had received treatment with a conventional electrocautery
only in the retrospective group.
Findings / Results:
No significant differences were found neither for calculated
blood loss, with 1397 (SD±452) ml in the bipolar sealer group versus 1452
(±530) mL in the control group (p = 0.66), nor for blood transfusion rates of
53% and 46% (p = 0.89), respectively. Four controls were readmitted within
90 days follow up.
Conclusions:
The use of a bipolar sealer in a TKA revision setting without the
use of tourniquet did not reduce blood loss or blood transfusion rates.
